Audio Technica ATW251 Wireless Unipack System

ATW-R250 receiver and ATW-T201 transmitter

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 body-pack 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, 1/4″ 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
