Full XLR Pinout(XLR3, 4,5,6) – Types & Advantages

Last updated on April 5th, 2024 at 11:05 am

XLR is an electrical connector mainly used for cabling in audio and video applications . These connectors are also used in lighting control, low-voltage power supplies, etc. XLR connector was discovered by James H Cannon (the founder of Cannon Electric in Los Angeles). Hence they are also known as Cannon Connectors .

XLR connections fall under the dimension standard IEC 61076-2-103.

XLR connector was initially known as the X connector . Later, the latch (L) and a synthetic rubber compound (R) were added to this connector, the name became XLR connector.

The XLR connectors are circular. The most common XLR is the 3-pin connector , but there are other connector variants whose number of pins ranges from two to seven . All these variants have both male and female versions.

The pins of the XLR connector are arranged circularly as shown in the figure. Let us see the pinouts of the relevant types in XLR connectors.

Note: The article shows the pinout of the male version of the connectors. The pin arrangement in the female version is the exact mirror replicate of the male version.

XLR3 pinout

The number 3 here shows that it is a 3-pin XLR connector . It is the most common industry standard for balanced audio signals. We can see this XLR port in the majority of professional microphones. They are also used in electric wheelchairs and scooters. The pinout diagram of XLR3 is given below.

Note: A major advantage of the XLR connector can be understood according to this pinout. As we can see, pin 1 is the ground reference. Pin 2 and 3 are for the same signal with opposite polarity, i.e., Pin 2 carries the exact signal, and Pin 3 carries the signal in its opposite polarity. This method cancels out any electrical interference carried in the line.

XLR4 pinout

The XLR connector with 4 pins is mostly used in intercom headsets . Among the four pins, two pins carry the headphone signals and the other two pins carry the microphone signals. The other popular applications are in DC power connections and professional cameras used in the film industry.

XLR5 pinout

XLR5 is the standard connector for  DMX512 digital lighting control . It is used to carry dual-element audio signals like stereo signals. The XLR connector with 5 pins is almost similar to that of XLR4 except that it has an additional one pin for power.

XLR6 pinout

XLR6 comes in two types; “Switchcraft Type” and “Neutrik Type” . Switchcraft is a symmetrical connector and the other one is asymmetrical. The common uses of XLR6 are stage lighting control, intercom systems, professional stereo headsets with balanced microphones, etc.

Hot plugging

Hot plugging means inserting or removing a component from the system while the system is in use . In XLR3 connectors, the ground pin of male and female versions makes the first contact during insertion. Also, it disconnects the last during removal.

This ensures that no unnecessary noise enters the system while making the connection. Hence XLR connector gives better performance while using them in a live session.

Advantages of XLR connectors

• They’re capable of delivering the 48-volt phantom power that’s needed to power condenser microphones.
• Balanced wiring cancels out interference that’s being picked up along the way.
• They have a little latch on the connector to prevent accidental unplugging.

What is XLR male and female?

XLR connectors come in two genders, male and female, differentiated by their structure and function: XLR Male : This connector has three pins enclosed within a protective metal casing, commonly used in microphone cables as the output for audio signals. XLR Female : Featuring a socket with three holes to accept the pins of the male connector, this type is typically found on mixers, amplifiers, and other audio equipment, serving as the input for audio signals.

Is XLR better than Jack?

It depends on the specific needs and application. XLR connectors are often preferred for professional audio due to their balanced design, while Jack connectors are more common in consumer electronics and instruments.

What is 7-pin XLR used for?

A 7-pin XLR connector is commonly used for specialized audio applications requiring additional features like remote control, powering accessories, or multi-channel audio transmission.

XLR Connectors for Prosumer

Introduction.

XLR connectors, a mainstay in the professional audio industry, are increasingly finding their way into prosumer applications, such as podcasting, social media content creation and home recording studios. Despite their superior audio quality and noise immunity, understanding and using XLR connectors can present unique challenges. This article aims to explore these hurdles, providing an educational and nuanced understanding of the role of XLR connectors in prosumer applications.

Instantly recognizable, the XLR connector greets you with a happy, mildly surprised 3-pin happy face! In the 1950s, the connector and its variations satisfied a need for sturdy, robust point-to-point connection of balanced audio signals around studios and music venues. The cast metal shroud and optional locking mechanism means an accidental kick (or aggressive microphone gymnastics!) would not disrupt the audio feed.

Balanced audio, with its inherent robustness in the face of common mode interference, was the basis, with an associated GND pin, as well as the (separate) chassis GND which extended the shield of the cables used (but is isolated from the 3 conductors in the cable). The XLR quickly established itself as the connector of choice for long runs of point-to-point audio in professional applications.

Standard / traditional audio usage

There are four basic types of XLR connector:

• Chassis socket
• Chassis plug
• Inline socket (one end of a cable)
• Inline plug (the other end)

In order to make audio connection somewhat foolproof, the basic assumption is that if you see an XLR with pins pointing at you, there is a signal SOURCE on the other end; if you see an XLR “face” with receptacles, that will be an expectant input to a device or system.  Therefore, almost all cables have a socket on one end and a plug on the other (so are inherently directional). Similarly, for audio equipment interface panels, chassis XLR sockets are inputs; if a chassis XLR has pins pointing at you, that’s an audio output.  The directional cable trick also means that you can easily extend a run by connecting multiple shorter cables.  Great for Music venues or sound reinforcement where the equipment setup varies with venue!

The other item to be aware of is pin assignment:

• Pin 1 = GND
• Pin 2 = audio +
• Pin 3 = audio –

Note that in balanced audio installations, it can be frustratingly easy to invert the phase of the audio; hence the need for consistency on the cables & pinout for preserving absolute phase (+/-) of the audio signal throughout the signal path.

Mechanically, Pin 1 on the plugs is extended slightly so that the GND connection makes first contact on insertion, establishing a common potential between pieces of equipment, preventing potential damage of audio I/O circuitry upon connection.

XLR’s Expansion into Prosumer Applications

As the home recording industry blossoms, with higher quality audio capture & editing becoming much more affordable, the demand for professional-grade equipment interfacing is on the rise. This increase in the ability to capture a performance leads Prosumers wanting to use studio grade peripherals, such as DI boxes and microphones, which already are available as standard with XLR connectivity. Naturally, Prosumer Audio Interfaces started to offer XLR connections (mirroring the professional equipment), to realize the same benefits inherent to professional studios: superior audio quality and reliability. However, this migration isn’t without obstacles.

Adapting to a new Paradigm

Prosumer audio setups often encompass a blend of professional and consumer equipment, which can create compatibility issues. For instance, while many high-quality microphones utilize XLR connectors, not all recording devices or computers offer XLR inputs. Also, musicians want to be able to record instruments directly to mix with vocals – which requires a different connector on the Audio Interface. Rather than add multiple connectors, some Audio Interfaces use a combined XLR and TRS (1/4” jack) input socket – which keeps cost and front panel real estate down – but does create a set of electronic compatibility headaches for the front end circuitry!

XLR Microphones in Home Studios

Professional grade XLR microphones are becoming increasingly popular in home studios, typically offering superior audio quality compared to their USB counterparts. However, these microphones often require phantom power, typically supplied via an audio interface or mixer with XLR inputs, making use of the 3 pin XLR connectivity to remotely power an input capture device. This introduces a challenge for users who must navigate the complexities of audio interfaces, phantom power , and gain settings to properly use an XLR microphone.

The Need for Audio Interfaces

As touched on earlier, using microphones requires an audio interface or input device capable of supplying phantom power and performing the necessary conversion from analog to digital signals . Choosing and operating this equipment to optimize performance can be daunting for novices. Understanding gain staging, monitoring levels, overload behavior and clip avoidance requires a level of technical knowledge often unfamiliar to the prosumer market. The XLR connector is a welcome, easily understood “standard” with very little nuance to establish basic audio signal routing.

Practical Constraints

Having listed the numerous advantages of XLRs, practical constraints for Prosumer in-home use can temper adoption. XLR cables are generally thicker and less flexible than their USB counterparts, which can be cumbersome in a home studio environment. USB based mics are improving all the time, and – somewhat like the XLR – offer a universal connectivity. Plus, the cost of decent XLR cables and equipment can be a barrier to entry, despite the significant audio quality improvements they offer.

Overcoming these Challenges

Despite these challenges, the audio industry has made strides in simplifying the integration of XLR connectors into Prosumer applications. Comprehensive education resources, more affordable Audio Interfaces, and easy-to-use software are all playing a part in bridging the gap between professional and Prosumer audio. Furthermore, the undeniable quality improvement and range of choice of XLR microphones over standard USB options reinforces their value proposition.

Upcoming Revolution for XLR Connectors

The use of XLR connectors in Prosumer applications, while presenting a unique set of advantages and challenges, enables a trend towards higher audio quality in home recording and podcasting. As understanding grows and technology advances, it’s clear that XLR connectors will continue to play a significant role in this evolving landscape. With informed equipment choices and a bit of technical know-how, users can effectively navigate these challenges to realize the full potential of their audio and vocal endeavors – with easily understood audio signal routing and connectivity!

However, it is possible to use two separate XLR connectors for a stereo signal, with one connector for the left channel and one for the right channel. This is common in professional audio setups, where individual XLR cables are used for each channel to maintain a high-quality signal.

Can XLR Be Stereo?

A 3-Pin XLR connector itself is not inherently stereo, as it is designed for balanced mono audio signals. However, you can use a pair of XLR connectors and cables to carry a stereo signal by dedicating one connector to the left channel and another to the right channel. In professional audio environments, this is a common practice to ensure high-quality signal transmission with minimal noise and interference.

Technically, it is possible to create a custom cable that uses a single XLR connector to carry both the left and right channels of a stereo signal by assigning different pins to each channel. However, this setup is non-standard, and you would lose the benefits of balanced audio, which is one of the primary reasons for using XLR connectors in the first place.

What Is The Difference Between 5-Pin And 3-Pin XLR?

The main difference between a 3-pin XLR and a 5-pin XLR connector is the number of pins and their respective applications:

• 3-pin XLR: This is the most common type of XLR connector and is primarily used for transmitting balanced mono audio signals. The three pins have specific functions:
• Pin 1: Ground (shield)
• Pin 2: Positive (hot) signal
• Pin 3: Negative (cold) signal

The balanced signal helps to minimize noise and interference in the audio signal. 3-pin XLR connectors are widely used in microphones, mixers, and other professional audio equipment.

• 5-pin XLR: This type of XLR connector has five pins and is primarily used for transmitting DMX512 data for lighting control, as well as stereo audio signals in some cases. In lighting control, the 5-pin XLR connector allows for a more complex data transmission between lighting fixtures and controllers. For stereo audio applications, the pin assignments are:
• Pin 2: Left channel positive (hot) signal
• Pin 3: Left channel negative (cold) signal
• Pin 4: Right channel positive (hot) signal
• Pin 5: Right channel negative (cold) signal

This configuration allows for the transmission of balanced stereo audio signals using a single 5-pin XLR connector, although it is less common than using two separate 3-pin XLR connectors for stereo signals.

The primary difference, therefore, is the number of pins and their specific applications in audio or lighting systems.

What Audio Devices Have 5-Pin XLR Connectors?

5-pin XLR connectors are relatively uncommon for audio devices compared to the standard 3-pin XLR connectors. However, there are some specific audio applications and devices where you may encounter 5-pin XLR connectors:

Stereo microphones : Some professional stereo microphones use a single 5-pin XLR connector to output both the left and right channels of a stereo signal. In this case, an adapter or breakout cable is often used to split the stereo signal into two separate 3-pin XLR connectors for connecting to a recording device or mixer.

Intercom systems : Professional wired intercom systems, such as those used in broadcast or live event production, sometimes utilize 5-pin XLR connectors. This is done to accommodate additional functionality, such as separate channels for communication and program audio.

Audio distribution : Some high-end audio distribution systems, like those used in large-scale installations, might use 5-pin XLR connectors to transmit balanced stereo audio signals over long distances, though this is less common.

Ambisonic microphones : Some ambisonic microphones, which capture 360-degree sound fields, may use a 5-pin XLR connector to output multiple audio channels. However, it’s worth noting that many ambisonic microphones use other multi-pin connectors, such as 12-pin or even higher, depending on the number of channels they output.

In general, 5-pin XLR connectors are relatively rare in audio devices, and most professional audio equipment uses the more common 3-pin XLR connectors for balanced mono signals.

XLR connectors play a pivotal role in the professional audio and lighting industry, delivering high-quality signal transmission while minimizing noise and interference. 

The 3-pin XLR connector, widely used for balanced mono audio signals, has become an indispensable component in various audio devices such as microphones, mixers, and more. 

Although less common, the 5-pin XLR connector serves specialized purposes, providing solutions primarily for lighting control applications.

By understanding the differences and unique uses of these connector types, professionals in the audio and lighting industries can ensure the best possible performance and the highest quality results in their projects.

XLR Connectors

Description | Applications | Pin Assignments | Assembly Instructions

Description

Robust connector available in 3 to 5 pole versions. 3 pole version normally used on professional audio equipment for balanced connections both at microphone and line level. Provides a mono connection, for stereo signals a pair of connections will be needed (as for phono). Sometimes used for speaker connections on professional high-powered rigs, however for safety Speakon connectors should be used since this wiring carries high voltages and currents. 3 and 5 pole versions are used in lighting control systems.

Typical Applications

Audio - Microphones, Mixers, Amplifiers, Effect units etc.

Loudspeakers, however Speakon connectors should be used instead for safety

Lighting - DMX512 lighting control protocol

Wheelchairs / Scooters - Charging connection

Pin Assignments

Balanced Audio (3 pole XLR):

Pin 1: Ground / Screen Pin 2: In phase / +ve / Hot Pin 3: Out of phase / -ve / Cold

Unbalanced Audio (3 pole XLR):

Pin 1: Ground / Screen Pin 2: Signal Pin 3: Ground / Screen (connect to pin 1)

DMX512 (5 pole XLR):

Pin 1: Ground Pin 2: Data -ve Pin 3: Data +ve

Pins 4 & 5 are normally unused, but this can vary. They can be used to carry a second DMX universe, or power. In particular, some Pulsar & Clay Paky equipment carries 25V on pin 5, with respect to ground on pin 1. This is against the DMX specification, and care should be taken when interconnecting equipment using fully-wired 5-pole connectors and 5-core cables.

Originally the extra pair of pins were intended for return data, but the RDM protocol used on some modern equipment sends data on the same pins as the DMX data, and does not require connection of pins 4 & 5 to function correctly.

DMX512 (3 pole XLR):

The body of the XLR connector should not be connected to the screen / ground

Equipment manufactured by Martin may have the -ve and +ve swapped. 3 pole XLR connectors are not part of the USITT DMX specification, but are often used instead of 5 pole versions, particularly on cheaper fixtures & devices to save costs. Some devices may have both 3 and 5 pole connectors for flexibility, alternatively adaptors can be made to convert between the two connector types.

Connector Assembly Instructions

Normally solder terminals. Remember to thread the cover onto the cable before soldering. Some connectors (Neutrik or similar) have a chuck-type strain relief, others have a metal cable clamp. Squeeze this shut with pliers AFTER soldering, or the heat may melt the cable sheath.

JRDG Company Special – XLR pin assignment

Generic info.

For XLR connections worldwide there are two variants. Either pin 2 or pin 3 is hot, ie carrying the plus/normal/positive/non-inverting signal and the other carrying the inverting signal. With balanced equipment it doesn’t matter which pin is normal and which is reversed, as long as you use them consequently. This is relevant to because it can lead to the use of equipment in opposite phase, not only when combining Rowland gear with other brands but also when combining older and newer Rowland products because they changed the scheme. Most obviously it is important for the power amps as they feed the speakers either in phase or inverted phase thus moving the speakerunits backwards when they should move forwards. For preamplifiers it is less crucial because they, like cables, simply pass on the signal coming from the source. For cables indeed the pin assignment doesn’t make a difference as they simply transfer all pins on one side to all pins on the other side.

Older Rowland products use pin 3 for the normal signal and pin 2 for the inverted signal while the latest Rowland products, starting with the ICE power-based amps have the more common pin 2 hot arrangement.

Care should also be taken when using (supplied) XLR to cinch adapters. Here too either pin 2 or pin 3 can be connected to the normal signal. Most other brands use pin 2 for hot but Rowland (Cardas) adapters, like the amplifiers, have made a switch some time ago, with the older adapters using pin 3 and the newer adapters using pin 2 for normal signal.

It is easy to compensate for this by using the “phase” button available on all Rowland gear and most other brand’s gear. But bear in mind that by selecting this option, the sound may change due to another circuit or relay being in use. Most of the time it is best to select the proper phase at the digital level, like in the CD player or DAC.

Hot (+) pins per amplifier:

Model 102 – pin 2 Model 201 and 501 – pin 2 Current 300 series – pin 2 Older Model 302 – pin 3 Model 9 and 8 – pin 3 (rear switch switchable to pin 2) Model 10, 12 and 112 – pin 3 Model 2 and 6 – pin 3 Model 1 and 3 – pin 3 Model 5 and 7 – not confirmed but very likely pin 3

Hot (+) pins per integrated amplifier:

Continuum – pin 2 Concerto – not confirmed but most likely pin 2 Concentra I and II – pin 3

Hot (+) pins per pre amplifier:

Corus – pin 2 Capri – pin 2 Criterion – pin 2 Consonance – pin 3 Consummate – pin 3 Coherence II – pin 3 Synergy I, II and IIi – pin 3

Cinch – XLR Adapters

Above: old style Jeff Rowland pin3 hot adapters. These came with the model 6 power amps.

Above: new style Cardas pin2 hot adapters. These are pricy but sound much better than the no-name cheapo adapters.

I use both the older types that came with the classic Jeff Rowland components and the newer types available separately from Cardas, the newer ones are easily recognised from the outside by the black shrinkwrap and rhodium plating (silvery coloured as opposed to gold plated with the older ones). The older ones, supplied with the older amplifiere, are matched to the pin 3 assignment and thus connect pin 3 to the cinch tip and pin 2 and 1 to the cinch mass. The later ones are matched to the latest Rowland gear, thus connecting pin 2 to the cinch tip and 1 and 3 to mass. Beware: there may be intermediate versions around, like black shrinkwrap connectors that are nevertheless pin 3 hot but they would probably not be rhodium plated.

The usual way to connect a 3-pin XLR to a 1/4" TRS (AKA stereo jack plug) is to use the following pin allocation:

• XLR pin 1 to 1/4" plug sleeve
• XLR pin 2 to 1/4" plug tip
• XLR pin 3 to 1/4" plug ring

This wiring configuration gives you a balanced mono audio cable.

XLR connectors are rugged electrical connectors which are used mostly in professional audio and video electronics cabling applications.

Some examples of application areas of XLR connectors are:

• Sound and video mixers
• Microphones
• Studio equipment like amplifiers, professional CD players, mastering deck, etc.
• Active loudspeakers
• Lighting applications
• Industrial applications (Control circuits, etc.)

The international application standard IEC 60 268-12 defines wiring of XLR connectors. The following is a brief description of the 3 pole version. Pin 1 --> X ternal of cable (shield/ground) Pin 2 --> L ive (“Hot” /+ polarity) Pin 3 --> R eturn (“Cold” /- polarity)

Currently there are two configurations of conventional 6 pole XLRs. The NEUTRIK 6 pole XLR meets the industry standard according IEC 61076-2-103. Nevertheless NEUTRIK offers both types of 6 pin configurations. The standard NEUTRIK 6 pin has a black insert - the insert of the non-standard configuration is gray. The difference in the part #s is the additional “S”: NC6MX - standard 6 pole male XLR cable connector, nickel housing, silver contacts NC6MSX - same product with non-standard pin configuration

Yes, according to our tests they work properly for digital AES/EBU signals but we recommend our EMC and XCC series with a 360° ground contact to the chassis connector and a circumferential cable shield connection. These connectors are ideal for digital AES/EBU transmissions and optimized regarding EMI and RF-leakage.

The 2 piece D-Series connectors consist of an insert and a shell, this allows soldering the insert onto the PCB and locking it into the shell afterwards. In the middle of the insert your can see a hole with a slot. Use a '00' size flathead screwdriver (part # SD-1) to lock/unlock the insert in the housing.

Yes, you can remove the latch at the AA-, 3 pole A- and 3 pole B-Series.

Screws for chassis connectors with through holes depend on panel material and panel thickness. We suggest the following: Metal panel (Steel, Aluminum, Zinc) - Flat head thread forming screws, Pozidriv, DIN 7500 M, zinc plated, M3 x length (drilled hole ~ 3.1 mm) - Flat head metric machine screws, Pozidriv, DIN 965A, zinc plated, M3 x length (thread M3) Plastic Panels PT-flat head screws, WN 1413, zinc plated, KA30 x length (depends on material, ~ 2.4 mm) For various chassis mount versions we offer correspondig screws. (A-Screw-1-8, B-Screw-1-8, E-Screw-1-12)

It is possible to use any aluminum 1/8'' or 3.2 mm 90° countersunk blind rivet. We suggest drilling a hole diameter of 3.3mm for the panel. It is possible to use pneumatic, electrical or hand riveting tools.

XLR PIN Assignment/Reverse Polarity Question

• Add to quote

I know this sounds like a silly question but I'm going to ask it anyhow: First the setup: Pre-Pro using Pin 2 as hot on the XLR Pin assignment on the outputs (Marantz AV7704) Amp using Pin 3 as hot XLR Pin assignment on the inputs (Emotiva XPA Gen3) Speakers are now out of phase due to the reverse polarity of PIN's 2 and 3 in the XLR connectors between the Pre/Pro and the AMP I was going to buy "XLR (F) - XLR (M) COUPLER--POLARITY CROSSWIRED. PHASE REVERSE" but was told the better option is to just reverse the speaker wire + and - at the amp end. So the question:..... Will reversing the speaker wire at the amp end have ANY side effects or negative impacts on the AMP/Speakers/Sound or anything in the chain?  

As is often pointed out in the various Marantz pre/pro Owner's threads ... Marantz is using the U.S. and industry standard for XLR connections with pin 2 the + (hot) connection. The Owner's manual is in error. Audyssey often finds speakers to be found "out of phase" for numerous reasons (eg. room acoustics) even when the wiring is correct. Simply select "Ignore" and continue with the EQ.  

The Manual shows 2 is hot and the back of the chassis shows the same too. But I think Emotiva has the Hot on pin 3 no?  

This issue has me confused also. Is it a concern the Marantz & Emotiva use different pin assignments or not?  

Yes. But their answer to me was the above. Swap the + and - of the speaker wire at the amp end. So I asked the question. " Will reversing the speaker wire at the amp end have ANY side effects or negative impacts on the AMP/Speakers/Sound or anything in the chain?"  

SOWK said: I know this sounds like a silly question but I'm going to ask it anyhow: First the setup: Pre-Pro using European XLR Pin assignment on the outputs (Marantz AV7704) Amp using the USA XLR Pin assignment on the inputs (Emotiva XPA Gen3) Speakers are now out of phase due to the reverse polarity of PIN's 2 and 3 in the XLR connectors between the US and European standards.

bigguyca said: Marantz has pin 2 hot which is the standard, EIA Standard RS-297-A. Emotiva has pin 3 hot, which is not standard, and is very rarely seen. Don't bring countries and continents into all this, you are just confusing the issue for no reason. Refer to the Technical usage information section, Three-pin audio use , on this Wikipedia page: https://en.wikipedia.org/wiki/XLR_connector Click to expand...

So now that it is official... Emotiva is strange. Can someone answer the question " Will reversing the speaker wire at the amp end have ANY side effects or negative impacts on the AMP/Speakers/Sound or anything in the chain?" I know logic says NO... but just in case I would like a professionals answer if possible.  

No. Longer answer: In practice it will not matter. There are those who claim to hear absolute polarity, but (a) not all source material maintains absolute polarity, (b) sound is an AC signal so you won't hear it anyway, and (c) your AVR or pre/pro will automatically compensate for it whether you swap wires or not. Swap if it makes you feel better but the end result will be the same. Aside: There used to be differences among continents and regions but for some time now (many years) everyone has followed the same convention with respect to XLR pin-out. FWIWFM - Don  

Just out of curiosity I asked Emotiva to confirm how they wire the connectors on their amps, and this is the response I received a few minutes ago from their tech support: "All Gen 3 amps are pin 3 hot, pin 2 cold (out of phase). If using with Marantz XLR outputs, flip the negative and positive speaker wire leads at the amp (hook them up backward). " So that is why when I ran Audyssey with a Marantz amp I have it was reported that all of my speakers were out of phase. Interesting. EDIT: After getting the above response, I asked if there was some reason for the doing it this way. Their answer was: "It was too technical for me to understand. I asked engineering one day and he told me the technical reason why it lowers the floor noise to do it this way, and he lost me. This has been several months ago and I don't recall the specifics. But it does help with the floor noise to flip the incoming phase. " Regards  

Well, yes, if Emotiva has it backwards, then if you want to be correct, you wire the speaker backwards. Basically when the signal goes one way, the speaker cone gets sucked in, and when it goes the other way, it gets pushed out. The thing that really matters is the phase is correct for all speakers - so when the signal all goes the same way, the speaker cones move the same way (in or out). Very few people can detect absolute phase, but it's easy to detect wrong relative phase. As it is, using the Emotiva flips the phase of the speakers connected to it. Nothing wrong with that, electrically it makes zilch of a difference if you connected the hot to the cold and vice versa. But if you connect the speakers properly, then those speakers will be opposite in phase (180 degrees out). You will have to reverse the phase of all the speakers not hooked to the Emotiva so they all have he same phasing. Of course, the simplest solution is have enough Emotiva amps that flip the phase for every speaker, so it doesn't matter anymore. To flip the phase, either flip a phasing switch, swap the + and - connections to the speakers, or swap it at the input. Speakers aren't inherently polarized, the + and - are there so if you hook them all + to + and - to -, they will be phased correctly. But if something is flipping them 180 degrees, then swap it. Note that phase detection is hard using the measurement mike, as room acoustics play a strong role. The best way to test is a phasing test disc that plays sound in and out of phase and make sure in phase sounds directional, while out of phase sounds indeterminate and fuzzy.  

lovingdvd said: Hi all - just coming across this, and really can't believe what I'm reading. Maybe it does not make a difference in the end, but it would sure have been nice to know, especially had I added a non-Emotiva amp to the mix. Can we get a good explanation for why they are doing this? Can we really say for certain that as long as all speakers are out of phase, the end result is identical? I did blow a couple tweeters for playing my KEFs too loud a few months ago , but I assume this reverse polarity did not exasperate the issue? Are there any other amplifier manufacturers that intentionally reverse polarity as well? I've had a 15 channel all KEF Atmos setup powered by three XPA-5 Gen 3 amps for about 1.5 years. Whenever I would run Audyssey (quite a bit lately in particular, now that I upgraded to the Marantz 8805) it would complain that all the speakers were out of phase. I was 100% certain that the wiring was not crossed at the rack or at the speakers, and read in many places that sometimes Audyssey gets the phase wrong, and if we are sure it's right, just ignore the warning, which I always did. So I had just assumed that Audyssey was incorrectly detecting the speakers as out of phase due to some characteristic of the KEF or my room treatments etc. Now I learn that Emotiva is intentionally reversing the polarity. What could be a possible GOOD reason for them doing this? Also can this in any way damage my speakers or shorten their lifespan? I suppose technically this also means my subwoofers are running out of phase in relation to all the other speakers, since nothing is set to run out of phase. Not sure if that matters, since REW FR sweeps show excellent post-calibration results. Is this REALLY something I can just completely ignore and forget I even knew about, assuming all my speakers are powered by their amps (except the subs), with ZERO implications? If there is any possible implications, is it perfectly safe for the speakers for me to reverse the polarity of the speaker wires at the rack? That would be by far the easiest way for me to reverse it. Although in doing so, it may throw off my excellent subwoofer (x4) calibration, which is ideal as it is, in which case I then may have to reverse its polarity as well. So if you guys can tell me with absolute certainty just to ignore it with zero implications (as long as I remember this if adding speakers in the future not powered by Emotiva) then that's what I'll do. Thanks! Click to expand...

Does anybody know if the Emotiva Gen2 amps are designed the same as the Gen3 with regard to the XLR pins? To me, this is quite alarming.

Cables & terminations

The typical termination standard between Linn products are:

Audio Transformer

Linn DS/DSM/Hub Output configuration: Fixxed level, there is NO volume control even in Post Eq mode. Linn DS/DSM/Hub Input configuration: 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz : 16bit and 24bit streams

Exakt Cables

ALL FOUR pairs of the cables are used in the Exakt-Link cable. This is NOT an ethernet transport cable but an Exakt transport cable. These pairs are used to transmit the audio data, power triggers and a master timing control to ensure that the audio from all channels are in perfect sync.

The Exakt-link has been designed to operate with the CAT-5 cable electrical specifications for signal timings. There have been NO changes to this design for any other CAT cable standards. (updated 2019)

• CAT 5/5e UTP/FTP
• CAT 6/6a UTP/FTP

Cat-7 and Cat-8 cables may not work well with an Exakt system. For a trouble-free, reliable, high performance installation, we recommend use of Cat 5 or Cat 6.

Typical Ethernet 100Base-T length restrictions guide :

EXAKT-LINK CANNOT be used with:

• Ethernet Network Routers,
• Ethernet Network Switches,
• Ethernet Isolators,
• Ethernet conditioners,
• HomePlugs/Ethernet-over-Mains devices
• WLAN bridges etc

Exakt-Link can ONLY be a CAT5/6 cable from Exakt socket to Exakt socket

EXAKT LINK terminations

• The cables are paired up using OUT > IN style connections.
• Any Linn product with these sockets can be linked together. This means you can link a Klimax DS/2 to a Majik ExaktBox-I and have a fully working Exakt system
