COS-11s

Common name: Sanken COS-11s

Production Status: Discontinued / Vintage

The COS-11s is a miniature lavalier microphone ideal for broadcast, location recording and theatre use. It has a 2.1 mm rugged sweat resistance that stays pliable through extended use. It features a 95 dB dynamic range, high output, low noise and an extremely smooth omnidirectional pattern. The PPS (Polyphenylene Sulphide Plastic) diaphragm gives it humidity and temperature stability and the vertical diaphragm placement protects against sweat and spray. A three-layer windscreen minimises pops, sibilance and wind noise. Red marked version for higher sound levels (Max SPL 134dB and sensitivity 8mV/Pa). PT version for wireless use (no connector), BP version for battery power/phantom operation.
