Audio-Technica ATW-902A System 9 VHF Wireless Handheld Microphone System
This system is a four-channel frequency-agile wireless system designed to provide rock-solid performance along with easy setup and clear, natural sound quality.
Designed for live sound reinforcement applications. The system consists of a wireless VHF receiver and a wireless VHF handheld microphone transmitter.
The receiver utilizes two dipole antennas for extended range, and allows you to select your VHF transmission frequency from 169 to 172 MHz.
The receiver includes LED indicator lights for channel, RF, and AF peak. The back of the receiver includes a volume control knob, a squelch control knob, a balanced XLR audio output, and an unbalanced 1/4" audio output. The receiver also includes a power cord hook to prevent accidental pull-out of the DC power supply.
The handheld microphone transmitter is powered by two AA batteries and includes a battery status LED indicator, channel selection DIP switches, and a power/mute button.
