AKG WMS4500 HC577 Wireless Headset Microphone System

The AKG WMS4500 HC577 Wireless Headset Microphone System is ready for all situations requiring absolute freedom of movement, like presentations or live stage shows.

Features

: - Adjustable headband and left/right selectable boom for maximum comfort and flexibility
- Dual-diaphragm transducer for suppression of cable noise
- Resistant to moisture, perspiration and salts withstands sudorific stage performances
- Interchangeable capsule module for quick and easy service
- Omnidirectional polar pattern for unchanging sound quality in all directions

The HC577 L is an extremely small reference head-worn microphone, designed for on-stage use. The microphone uses a CK77 omnidirectional transducer that has been an industry standard for lavaliere capsules for years and ensures superior audio performance.
A patented body design protects the microphone from moisture and perspiration. The capsule uses the signal of two vertical diaphragms mounted back to back, mixed out of phase to cancel out mechanical and cable noise.

The set includes:
- 1 PT4500 pocket transmitter
- 1 SR4500 receiver
- 1 HC577 L fleshtone head-worn microphone

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

WMS 4500

The wireless receiver shall operate over a 30 MHz UHF frequency range in one of 8 bands from 500 MHz to 863 MHz, with a wide range of possible frequency settings. The wireless microphone system shall incorporate factory-optimized sets of both sending and… read more receiving frequency modules that are built into both transmitters and receivers. Each frequency set shall comprise a 30 MHz UHF band and offer up to 1,200 discrete operating frequencies within that band. The receiver shall operate on the true diversity principle, and the switching circuit shall be inaudible. Total harmonic distortion at 1 kHz for rated deviation shall be no greater than 0.3%. The receiver shall provide for a manual squelch adjustment as well as an automatic squelch option (tone code squelch) for optimum system operation. Audio output shall include a balanced XLR connector as well as an unbalanced 6.3 mm / 1/4-inch jack connectors. The output from the 3-pin XLR-type connector shall be adjustable in 3 steps (-30, 0, +6 dB). A RJ11 data port for connecting HUB 4000 Q communicating with Harman System Architect PC software. A logic out connector shall be provided. The receiver shall be controlled by a jog wheel and shall provide a backlit color display as well as a programmable LED ring (red/green) showing the overall system status.
