WMS4500 CK77 L SET



The perfet WMS4500 set for all-round application on theater stages.
Ideal for recording, monitoring and broadcast.

CK77 WR L:

  • Dual-diaphragm transducer for suppression of cable noise
  • Resistant to moisture, perspiration and salt withstands sudorific stage performances
  • Interchangeable capsule module for quick and easy service
  • Omnidirectional polar pattern for unchanging sound quality in all directions

The CK77 WR is an extremely small, omnidirectional professional lavalier microphone. The patented dual-diaphragm capsule has been designed to protect the transducer from moisture and perspiration.

The CK77 WR uses two vertical diaphragms mounted back to back to cancel out mechanical and cable noise by mixing the signals of both capsules out of phase. Its ruggedness and superior sound quality make it an excellent tool for theater and broadcast applications. The screw-on module capsule allows quick and easy service of the microphone.

The set includes:

1 PT4500pocket transmitter
1 SR4500receiver
1 CK77 WR Llavalier microphone

1 belt clip, 2 AA size batteries, 2 antennas, 1 rack mounting kit, power supply

System components are also available separately.
