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.

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?
Asked by: Nathan
Unfortunately, there are no dongle-style adapters to connect to the Sony cameras with Multi Interface Shoes.

The Sony a6000 does not have any audio jacks on board. Would this allow external audio to be recorded to that body?
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.
