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.
