The Sony XLR-K3M is a dual-channel digital XLR audio adapter that allows you to connect microphones and other audio sources to cameras equipped with a Multi Interface Shoe. Released alongside the a7R IV, which benefits from its built-in digital audio interface, the adapter is able to produce its best quality by delivering a digital audio stream directly to the camera through the Multi Interface Shoe. Other Sony cameras with the standard MI Shoe can still make use of the microphone as there is a selectable digital/analog output.

The XLR-K3M features two XLR-1/4" combo mic/line inputs with 48V phantom power, and a 3.5mm stereo input with plug-in power, all with individual level controls. Intuitive controls make the adapter easy to use right out of the box. An ECM-XM1 shotgun is included so you can immediately start recording your YouTube videos, Facebook Live streams, and interviews, at home, in the studio, or on the go.

Digital Sound with Low Noise

When connected via the Multi Interface Shoe of a compatible camera that features a built-in digital audio interface, the audio signal is directly transferred to the camera in digital form so that no degradation can occur. A simple switch also provides compatibility with a wide range of cameras using an analog interface.

Effective Controls for Clear Sound

Controls Include: Record level (Auto/Manual), record level link (Input 1-Input 2), attenuator, and low-cut filter (100/300 Hz).

Mechanical Noise Suppression

An advanced shock and vibration suppressing design effectively minimizes low-frequency and handling noise, which can degrade audio quality. The absence of connecting cables, when used with a compatible MI Shoe, also means that no noise can be transmitted to the microphone mechanically via cables and connectors.

Cable-Free Connection

Simply clip the microphone into the Multi Interface Shoe on a compatible camera for direct power and audio connections without the need for extra cables or batteries. Sony's Multi Interface Shoe offers intelligent connectivity and control for a variety of accessories, providing maximum flexibility and mobility.

Flexible Setup

An MI Shoe extension cable is supplied, giving you the flexibility to position the XLR-K3M to accommodate professional rigs and camera cages.

ECM-XM1 Shotgun Microphone

An ECM-XM1 supercardioid monaural microphone and a fur windscreen for wind-noise reduction are supplied.

Sony XLR-K3M Reviews

Outstanding piece of gear. Takes the a7siii into Fx6 territory.

I've used it with the shotgun mic that comes with it (and it's not bad). I've used it with the Rode wireless go. I've used it with the Sennheiser G3 wireless setup and with the MC46 using phantom. Interviews, weddings etc. Solid every time. If you opt for the 24 bit sound make sure you or your clients have pro level editing software or it may not fly too well. Love the cable that allows you to move the unit to a different part of your rig and out of the way of a top handle. The one drawback is it's a little clumsy feeling/looking. It does take a lot of space. Would be great if i could remove the mic mount to trim it up a little.

Excellent mic choice

Only drawback was waiting for 3 months to receive the mic due to backorder. However, it was worth the wait. This is the perfect microphone to pair with the A7S3. I've got 2 other mics and this one is the simplest to mount and use and I enjoy that it uses power from the camera. Makes everything so convenient. On top of it all, the sound quality is superb. Definitely recommend.

It's a great adapter that I'll get a ton of use out of. The only thing I didn't account for that really bugs me is that the extension cable that comes with it isn't compatible with my cage rig. the top handle gets in the way of the cable that can't be reoriented. Maybe my use case is rare, but I think it worth mentioning to anyone who uses a cage with a top handle.

Why?

It's only 16 bit unless you're using Adobe Premiere Creative Cloud because the 24 bit codec is not recognized by any others. Supposedly you can convert and use the 24 bit, but I didn't have any luck and am an ex-software engineer. When I brought the files from my a7siii into Creative Cloud Premiere, some of the audio from the same session was blank, as in none. So I would not trust this thing for anything. The 16 bit quality is low. The mic quality is low. The design is unnecessarily klunky and flimsy/amateur looking. No lights on the dials, and they're also shaded, so good luck seeing the microscopic numbering on the wobbly wheels. When you use the attachment to get the contraption off the camera, the cord is in the way of why you moved it. This might go directly digital, but theXLR is still analog, so I don't see any benefit of this over an external recorder. It's worse, and costs more.

Here is the thing. I LOVE having the XLR outputs for my Sony A7SIII. I contemplated between getting the FX3 instead, bit, as a hybrid, I just kept my A7SIII and opted for the XLR-K3M for audio solution. The PROS: - Better sound than Rhode+ - Ability to connect two 3 mics - can use wireless XLR without losing quality - come with adapter to extend where you could connect - decent price for its quality. Honestly, aside from the FX6's ND and other specs, I think this mic levels up the A7 cameras to a point near production ready. The CONS - If you use a top handle, it might be tricky to use the adapter (which presses against it) to connect the kit, so you lose hand space and it becomes somewhat unbalanced. I would recommend getting a side handle, so that you don't need to connect the extender. Overall, I am super happy with it. And it works great for interviews, and having back up audio. :)

So far, so good!

I used this for the first time last week on set. I paired the device with a Sennheiser 416 and it sounded great! The unit itself is light and plastic but it works well.

Spotty connectivity and Boom Mic was bad out of the box

By Doug

When it works it is great. The audio quality is there and I'm using it for two feature films right now. It causes me stress though. I ordered it in February and it didn't arrive until June (2021) so I had to rent one for 40 days. The rental unit had a problem periodically being recognized by the camera (Sony As7iii). I'd have to turn everything off and back on...keep messing with the hot shoe mount by pulling it off and putting it back on...tightening it, etc., and eventually it would work. Once it was working, I learned to leave it on the camera and not break the camera down. That wasn't practical on the road, however. I found myself praying a lot every time I connected it with a film subject in front of me. I was traveling 100% and had one day off to come home and found the box of the one I ordered at home. I tried it out and it had that same connection issue initially, but eventually, I got it to recognize it. I tested it with my wireless lav system (Seinheiser) and everything worked and I mailed back my rental unit and took this newly purchased unit back on the road for the next 2 weeks. The problem for me was I never tested the boom mic it came with. The rental unit's boom mic was fine. However, the purchased unit's boom mic was bad out of the box which I learned on set. At first, I thought it was the camera not recognizing the unit again, but eventually, I figured out it was just a bad boom mic. The problem now is I can't get any rental companies to rent this unit to me...they are rented out, so I'm stuck with a bad-out-of-the-box unit here (boom mic) and renting another boom mic to attach to it to make the whole thing work. The fact that I'm going through this effort and not going back to my days of recording on a separate device and synching in post is a testament to how good the sound in this unit really is when it works...not to mention how amazing it is have synched up audio always. I like it, and hopefully, future software upgrades help with the buggy connection issues. I'll just be using another boom mic because I'll have to keep this bad unit past the 30 days return cycle. I have no choice. Even with those negatives, I'm very happy to have this unit and recommend it if you want to capture pro audio directly into the camera. That part is amazing, and the ability to adjust the audio at the point of input is really a dream for both channels. I've been recording two separate people for more interview styles and actors with two people using two separate lavs and pulling both into the camera.

I read through all the Qs and still feel I'm getting conflicting answers, so I'll ask my specific question here. Can I input TWO mics into the XLR channels, and then a stereo mic into the 3.5mm input, and record all of them at the same time (with the 24bit 4 channel option in the a7s iii)??? Thank you!!
Asked by: Alexander
Yes, you can connect microphones to all three inputs on the XLR-K3M and record them simultaneously onto four channels of audio with the a7S III. Here are instructions based on information provided by Sony which apply to the a7S III and any of the Sony cameras that support 4-channel audio recording: To record the input audio from the INPUT1 jack(XLR) to the CH1 channel on the attached camera; the input audio from the INPUT2 jack (XLR) to the CH2 channel; and the input audio from the INPUT3 jack (3.5mm) to the CH3 and CH4 channels, set the switch to “IN1·IN2.” To record the input audio from the INPUT3 (3.5mm) jack to the CH1 and CH2 channels on the attached camera; the input audio from the INPUT1 jack (XLR) to the CH3 channel; and the input audio from the INPUT2 jack (XLR) to the CH4 channel, set the switch to “IN3.”

Just to set this straight: can you record four channels (XLR 1, XLR 2 & 3.5 mm stereo) with the A7S III?
Asked by: Ignacio
No, the XLR-K3M is a two-channel adapter kit designed for Sony cameras that use their Multi Interface Shoe. The kit includes the XLR-A3M two-channel mixer/adapter and ECM-XM1 shotgun microphone. Only two microphones can be connected to the XLR-A3M - one on each of the XLR-1/4" combo jack inputs or one single stereo mic connected to the stereo 3.5mm mini jack input.

Does Sony offer anything similar to this, but simply a multi-interface shoe connection to xlr adapter? I would like to see a simple multi-interface shoe adapter to 1, 2, or 3 XLR inputs, and instead of being a box, it's a dongle cable. Does Sony have any plans for something like this?

Unfortunately, there are no dongle-style adapters to connect to the Sony cameras with Multi Interface Shoes.

Asked by: Ian
https://support.d-imaging.sony.co.jp/www/cscs/accessories/compatibility.php?area=gb&lang=en&mdl=XLR-K3M&cat=3 According to this page, the XLR-K3M is compatible, in analog mode, with several cameras in the A6000 line, but the A6000 itself is not listed as compatible. It may lack even the analog signaling interface in its multi-interface smart shoe, or perhaps it does work but Sony didn’t test cameras that old when it came out with the K3M.

Can you use an XLR Y cable to get a backup signal ...

Can you use an XLR Y cable to get a backup signal at lower db? I.e. connect one cable to the mic (supplying phantom power) and the other two cables to Input #1 and #2. Set Input #1 at say 20db and Input #2 at 10db, thus giving you a backup second signal 10db lower. Clearly I don't want to blow my unit.
Asked by: Paul
We would not recommend this set up due to two reasons. 1) Since phantom power may not travel properly through a y cable, you would have to power the mic before the splitter , utilizing a separate phantom power supply. 2) By splitting a mic level signal with a y cable, the level going to each input will already be reduced. Any further reduction in level could further noise into the signal. If you want a backup recording, we would suggest using a separate audio recorder such as the Tascam DR40x which would offer a separate safety track recording.
