Audio-Technica ATW-902A Overview

The Audio-Technica ATW-902A System 9 VHF Wireless Handheld Microphone System is 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.

Selectable VHF Transmission Frequencies
Select four channels from 169 to 172 MHz
Dipole Antenna for Extended Range
The receiver utilizes two antennas to improve the range of the system
Squelch Control
The receiver features a squelch adjustment knob that controls the threshold for the radio signal that regulates audio output. If the radio signal from the microphone drops below the threshold, the squelch control mutes the audio output to prevent the transmission of radio interference and white noise from entering the speakers
