AKG WMS4500 overview

  • 1Description

The BD8: 570.1 to 600.5 MHz, of the AKG WMS4500 CK77 Instrument Set is a reference multichannel wireless microphone system providing high channel quantity, reliability, and easy setup. The CK77 WR-L’s ruggedness and high sound quality make it a handy tool for theater and broadcast applications. The CK77 Set includes a SR4500 Wireless Stationery Receiver with a frequency of BD8: 570.1 to 600.5 MHz, 50mW transmission power that provides maximum ease of use with an automatic setup function and scan of the radio frequency environment; a PT4500 Bodypack Transmitter with enhanced wireless audio quality for instrumental and vocal use; a CK77 WR-L Lavalier Microphone designed to protect the transducer from moisture and perspiration; a belt clip; a 19“rack mount kit; LR6 batteries; and whip antennas.

The package is a reliable workhorse in huge installations and on tour. An optional network remote control allows frequency co-ordination and monitoring of multi-channel systems via PC software System Architect, Apple iPhone/iPad/iPod or via Soundcraft Vi consoles.

The SR4500 Wireless Stationery Receiver provides maximum ease of use with an automatic setup function and scan of the radio frequency environment. The rehearsal mode supports the engineer during sound check with information on the systems signal quality. The programmable status monitor shows all relevant system information on an illuminated multicolor LED ring. Its precise battery life readout in hours is a valuable advantage in wireless applications.

The PT4500 Transmitter is an analog reference wireless body-pack transmitter with superior wireless audio quality for instrumental and vocal use. The pilot tone prevents unexpected system startup noise, continuously sending transmitter data, including mute switch position and remaining battery life, to the receiver. An optional RMS4000 external mute switch (sold separately) allows the user to mute the transmitter remotely. The transmitter offers a battery life of 15 hours with 2 standard AA-size alkaline batteries. With the integrated charging contacts, the optional BP4000 battery-pack (sold separately) can be charged inside the transmitter.

The CK77 WR is a small, omnidirectional professional lavalier microphone. The dual-diaphragm capsule has been designed to protect the transducer from moisture and perspiration. The CK77 WR uses 2 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 a handy tool for theater and broadcast applications. The screw-on module capsule allows quick and easy service of the microphone.
