Sanken CMS-50 M-S Stereo Microphone

The Sanken CMS-50 puts an M-S stereo pair in one 137 mm body, with separate mid and side outputs so the width of the stereo image is set at the mixer or in post.

The mid capsule is cardioid and the side capsule is a figure-8, and both outputs come from one XLR-5M connector. Record both outputs to keep the width open until post, or decode them at the mixer: left is M plus S, and right is M minus S. Raising or lowering the S level widens or narrows the image, and with M and S at the same level the stereo angle is 127°.

Sanken built it for ambient recording at field sports, film shoots, and operas. At 130 g, it mounts on a camera or a boom pole. A high-pass filter switch changes its low-frequency response. Each channel draws 4 mA of 48 V phantom power.
