Little more than half the length of the CS-1e, the Sanken CS-M1 moisture-resistant ultracompact shotgun microphone is designed for capturing dialogue, foley, and sound effects in sterling sound quality while always staying out of the shot. Compared to the CS-1e, the CS-M1 is advantageous when used on close-range sources that don't produce extended bass frequencies.

For independent and major film, television, and location recording gigs where you need a space-saving mic that remains a featherweight on boompoles or short-lens cameras, the CS-M1 is ideal. It's short interference tube and consistent off-axis tone also make it well suited for indoor use.

The microphone exhibits a supercardioid polar pattern at low and midrange frequencies, and transitions to a lobar pattern at high frequencies, allowing it to attenuate the 90° off-axis points by about 10 dB from 250 Hz to 2 kHz and by over 14 dB at 4 kHz.
