Sanken COS-22-PT Dual Capsule 2-Channel Lavalier Microphone System with Pigtail

Sanken COS-22-PT Dual Capsule 2-Channel Lavalier Microphone System with Pigtail

The COS-22 two-channel lavalier microphone is the result of a joint engineering effort by Sanken and NHK to create a new generation of microphones designed to meet today’s highest audio standards while satisfying the concealment requirements of high-resolution film and video.

Ideal for voice or instruments in live broadcasting, location recording and studio applications, the COS-22 utilizes the world’s most advanced precision craftsmanship for the ultimate in sensitivity, natural sound and hidden capabilities. In addition, the COS-22 can be used as a noise cancellation directional microphone pair by reversing the phase of one channel before summing the two outputs.

The proprietary vertical diaphragm introduced by Sanken is an example of its innovative and unique product designs. Often simulated, Sanken products provide the optimum results and the highest quality available today.

Key Features

• Wide pick-up area “plant mic”
• Ultra-miniaturization plus high performance for concealment applications
• Complete redundancy from capsule to connections
• High output and low noise with extremely smooth omni-directional pattern control over a wide frequency range
• Exclusive PPS (Poly-phenylene-sulfide) diaphragm provides dramatically higher humidity and temperature stability, outperforming all other condenser lavaliers
• Vertical diaphragm placement protects against moisture
• Built-in 3-layer windscreen minimizes pops, sibilance and wind noise
• Holder clip provides critical distance between microphone and clothing for avoidance of mechanical/surface noise
