Sanken Super Short M/S Shotgun Mic

Overview
The CMS-50 is a unique and lightweight stereo condenser shotgun microphone, weighing only 4.6oz and measuring 5.4′′ in length. It offers a versatile M-S (Mid-Side) configuration, allowing for adjustments to the stereo width from mono to stereo at the mixer or in post-production. With its two outputs, cardioid and figure of 8, it provides high-quality sound and can be used for various applications such as field sports, movies, and operas.

The CMS-50 is designed to be rugged and dependable, making it suitable for use in demanding environments. It also features advanced RFI rejection and a HPF switch for changing low frequency characteristics. With its compact size, it is ideal for boom pole operation on film shoots and can be easily mounted on cameras with short lenses. The M-S signals from the CMS-50 can be decoded to Left and Right using the optional MB-2D decoder or in the mixing console, allowing for adjustments to the stereophonic angle.

About the Sanken Super Short M/S Shotgun Mic
The unique CMS-50 is a 5.4′′ compact stereo condenser shotgun that weighs only 4.6oz. The mic is especially suited to users that require the versatility and smooth stereo that an M-S design provides. Tight or wide patterns and premium sound, it can be camera mounted without interfering with even a short lens, yet still provide the quality of audio demanded by today’s professionals.

It is an M-S (Mid-Side) configuration which makes it possible to adjust the stereo width from mono to stereo at the mixer or in post production. The shotgun includes two outputs, a cardioid and figure of 8, which can be fed into the mixer for width adjustments. If both outputs are recorded then width can be managed in post.

Like all Sanken shotguns it is rugged and dependable with a wide range of applications where sound clarity and noise rejection are critical requirements.

Decoding M-S Signals from CMS-50

The CMS-50 outputs M and S signals. These can be decoded to Left and Right using the optional MB-2D decoder or can be decoded in the mixing console…

To derive the left and right channel outputs from M-S coincident microphone sources use the following summing and difference:
L ch : Sum of M and S
R ch : Difference between M and S

By connecting the outputs to the mixer as shown, both M and S signals can be decoded as L ch. and R ch. The angle between L and R can also be varied by the adjustment of the S ch. fader volume. When levels of M and S are the same, the stereophonic angle is 127°.
