AKG WMS4500 overview

  • 1Description

The WMS4500 HC577 L Fleshtone Head-Worn Wireless Microphone Set from AKG contains the PT4500 Pocket Transmitter, the SR4500 Receiver and the HC577 L Fleshtone Head-Worn Microphone. It is designed as a wireless set for live-sound and on-camera performance applications in which the vocalist needs a lightweight and low profile wireless microphone solution. When worn, the HC577 L places the mic in front of your mouth and it connects via its built-in 3-pin mini XLR cable to the PT4500 transmitter. The PT4500 transmits the signal to the SR4500 receiver which may be connected to your mixer and sound reinforcement system.

The HC577 L is a head-worn microphone specifically designed to be inconspicuous when used by performers on stage or on camera. The microphone uses a CK77 omnidirectional transducer and has a Teflon moisture shield that protects the microphone from moisture and perspiration. The two vertical diaphragms are mounted back to back and set out of phase to cancel out mechanical and cable noise. The dual-diaphragm capsule also has an additional gold-sputtered protective diaphragm that is designed to stop moisture and perspiration from damaging the transducer.

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 1,200. Using several WMS4500 systems in different frequency bands allows you to operate as many as 70 channels simultaneously. A 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 battery life readout feature, which monitors the battery life of the PT4500 transmitter, is especially useful in concert sound applications that call for continuous uninterrupted performance. 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. Furthermore the optional HUB4000 Q ethernet interface allows you to connect multiple SR4500 receivers for integration into the HiQnet audio networking system for remote monitoring and configuration from your Windows-based computer.
