The WMS4500 CK77 L Wireless Lavalier Microphone Set from AKG contains the PT4500 Pocket Transmitter, the SR4500 Receiver and the CK77 WR L Lavalier Microphone. It is designed as an all-purpose wireless set for stage, theater and broadcast applications.

The CK77 WR is a small, omnidirectional professional lavalier microphone. The patented dual-diaphragm capsule has been designed to protect the transducer from moisture and perspiration. The two vertical diaphragms are mounted back to back. This design helps to cancel out mechanical and cable noise by mixing the signals of both capsules out of phase. The screw-on module capsule is designed to allow for quick and easy service of the microphone.

The PT4500 is a pocket transmitter with an aluminum body. It has an RF output power of up to 50mW to maximize resistance to interference and dropouts. It also has a backlit display and a pilot tone system that sends transmitter status data to the receiver, including mute switch position and remaining battery life. The unit can operate for up to 15 hours on standard AA batteries, or up to 12 hours on the optional BP 4000 battery pack.

The SR4500 is a true diversity UHF receiver that is designed to provide maximum ease of use and a wide range of functions. It operates in a 30 MHz wide UHF band and each frequency preset provides up to 19 intermodulation-free channels. The maximum number of selectable frequencies is 1200. Using several frequency bands allows you to operate as many as 70 channels simultaneously. A large, backlit color display and a jog wheel are in place to make the SR4500 easy to use, and a programmable LED ring indicates important system parameters at a glance. The SR4500's transmitter battery life readout is designed for accuracy, which is especially useful in live sound applications. The SR4500 receives a pilot tone from the transmitter which contains status data including the remaining battery capacity. The pilot tone decoder also allows the detection and display of other important information including the current position of the transmitter's MUTE switch. The SR4500 also features Auto Setup and Environment Scan functions which automatically analyze the local RF environment, find usable frequency groups, and set frequencies. The optional HUB4000 Q integrates the SR4500 into the HiQnet audio networking system.
