Sony XLR-K3M Overview

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.

After trying various mics from other companies that miss lead my purchasing decision, B&H photo, video and audio, guided me to this Sony XLR-K3M which does not have a problem with phantom power! it gets great quality sound even in the ultra-loud environments I use it in. B&H is my one stop shop forever!

Great Audio, Awkward Design For Rig Users

By Yiran
Rated 4 out of 5
Date: 2025-11-27

It’s Very Obvious That This Product Is Made For Video Users — Which Means You Must Think About Your Rig Setup… Or The Lack Of One. If You Don’t Have A Rig And Don’t Use Any Hot-shoe Accessories, Then Honestly This Thing Is Perfectly Fine — Aside From Feeling A Bit Plasticky. But If You Do Mount Accessories On The Hot Shoe… You’d Better Hope You Have A Rig. And If You Do Have A Rig, And You’re Used To Putting The Monitor Or A Top Handle On Top, Well… I’ll Just Say This: Very Few Top-handle + Rig Combinations Will Leave Enough Room For This Extension Cable (of Course, Not Going To Work With The Interface Itself). With My SmallRig Setup, I Had To Solve The Problem In A Very “creative” Way. (To Be Fair, After Extending The Screw, It Turned Out Solid — Though The Center Of Gravity Definitely Went Up.) Audio Quality Is Good, And I Like The Two Different Low-pass Filters. As For The Dial… I’m Honestly Not Sure What To Say. I Really Wish It Had Some Tactile Feedback, Or At Least A Slight Stop At The Center Position. There Are Only Three Gain Levels Available, And You Can’t Control Them In-camera. At This Point, I Might Just Consider Switching To XLR Control Instead.

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.”
