Audio Technica ATW-251/H92-T8 Wireless VHF Head-Worn Microphone System (170.905MHz)

The Audio-Technica ATW-251/H92-T8 (170.905MHz) includes: a ATW-R250 receiver, ATW-T201 transmitter, and a PRO 92cW headworn black microphone.

Audio-Technica's Freeway 200 Series Wireless Systems are designed to provide reliable performance, easy setup and clear, natural sound quality. Each 200 Series professional VHF wireless system includes a receiver and either a bodypack transmitter or a handheld microphone/transmitter on a specific crystal-controlled frequency. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.

Features

• Easy operation and clear, natural sound quality
• Reliable performance and durable construction
• Advanced dipole antenna system for extended operating range
• Power, RF, and AF Peak indicators
• Volume control, ¼” output jack and space-saving power supply
• Rugged unidirectional dynamic element on handheld microphone/transmitter
• Variable microphone trim control and easily accessible On/Standby/Off switch on transmitters
• Professional locking connector on UniPak® body-pack transmitter
• Available in 7 system configurations

The ATW-R250 receiver is a compact wireless receiver for the 200 series Freeway system. The surface mounted unit features 8 selectable VHF frequencies, and diversity switching antennas. The combination of VHF, diversity operation results in fewer drop outs and noise. The rear provides both balanced and unbalanced output connections for further flexibility. It comes with a unique space saving power supply, perfect when multiple AC power supplies are employed as part of a system. The ATW-R250 also offers squelch and volume controls, 1/4 output jack, along with AF Peak, RF and Power indicator lights.

The ATW-T201 Body Pack Transmitter is a VHF bodypack transmitter for the Freeway 200 series wireless microphone system also. The transmitter accommodates compatible lavalier and head-worn microphones as well as instrument cables. Additional features include switchable RF power settings for increasing range whenever necessary.

The PRO 92cW wireless omnidirectional condenser headworn microphone offers a natural, smooth frequency response optimized for vocal articulation. The mic features a small condenser capsule; a lightweight, contoured earpiece; and a flexible boom that is easily repositioned for a comfortable fit. Terminated to fit Audio-Technica wireless systems, the PRO 92cW is a great headworn mic.
