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