Sanken CMS9-MS

The Sanken CMS-9 is a lightweight M-S stereo condenser microphone ideal for all studio and feild recording applications. Its unique design features an internal "Mid-Side" sum and difference processing circuit which, by eliminating the need for an external matrix box, makes the mic extremely mobile and easy to handle The CMS-9 outputs fixed stereo signals which can be input directly to a field recorder or portable DAT machine equipped with L-R inputs and 48V phantom power. Its unique two-layer windscreen and solid construction assure quiet recording, even in difficult outdoor environments where wind and handling noises can be a problem. Like all Sanken microphones, the CMS-9 features a one-micron titanium diaphragm that is light, strong, corrosion-free and immune to temperature and humidity changes. It uses the same capsules as Sanken's CMS-7 MS Stereo Mic, and offers Sanken's original Push-Pull capsule design, which gives it a sensitivity 6dB higher than similar sized non-Push-Pull microphones, It has a dynamic range of 111dB ( maximum SPL=130dB at1% THD ), a nearly flat frequency response, and inaudible self-noise (19dB or less) for a clear stereo image with clean, uncolored sound.

The CMS-9 MS Stereo Microphone incorporates two capsules: a mid-mic with a unidirectional cardioid polar pattern, and a coincidently mounted side-mic with a figure-8 pattern. This arrangement, which accurately determines spatial localization, reproduces natural ambient stereo sound fields. Since the M-S technique permits the source's soundwaves to reach both capsules in-phase, it is completely mono compatible.
