SANKEN / COS-11D PT-WH (WHITE)

[Ultra-small microphone capsule only] model that only has a built-in impedance conversion circuit. It is compatible with both 2-wire and 3-wire systems, making it ideal for use in wireless transmitters and high-performance built-in microphones.

■Product features
・ Compact and high-performance lavalier microphone with a diameter of 4 mm
・ Diaphragm is laid out vertically. The maximum effective area of ​​the diaphragm is secured within the diameter of 4mm, providing rich sound quality.
realization
・Achieves a non-disturbing omnidirectional pattern over a wide band
- Eliminate radio noise contamination caused by digital transmitters
・The 'PPS' vibration membrane specification provides high stability against temperature and humidity.
- Vertical structure prevents foreign matter (sweat, saliva) from adhering to the vibrating membrane.
- Strong water-repellent coating repels small amounts of sweat and rain.
・Four colors: black, beige, gray, and white
・High tensile strength is ensured by the cable clamp incorporating new technology.
- Adopts a cable that is resistant to bending and has passed bending tests over 250,000 times.
