The Sanken CS-1 is a short rifle microphone intended for film and TV but likely to find uses elsewhere too. The microphone is exceptionally short and light while retaining high directivity that is remarkably consistent – greater than 20dB front-to-back ratio across almost the entire frequency response. The CS-1 is small enough to fit onto ENG cameras but can also act as a high-quality boom microphone. The capsule is a Sanken original using a square diaphragm DC biased condenser design which can sustain SPLs as high as 137dB with only 1% distortion.
