Audio-Technica ATW-901A/G System 9 VHF Wireless Unipak System with AT-GcW Guitar & Instrument Cable

The Audio-Technica ATW-901A/G System 9 VHF Wireless Unipak System is designed for live sound applications. It consists of a wireless VHF receiver, bodypack transmitter, and an AT-GcW guitar/instrument input cable. The receiver uses two dipole antennas for extended range, and allows you to select your VHF transmission frequency (169.505, 170.245, 171.045, or 171.905 MHz). The receiver features LED indicator lights for channel, RF, and AF peak. The back of the receiver features a volume control knob, squelch control knob, balanced XLR output, and an unbalanced 1/4" output. The receiver also includes a hook to prevent accidental pull-out of the DC power supply. The bodypack transmitter is powered by two AA batteries and includes variable microphone and instrument trim, channel selection DIP switches, a Power/Mute button, and a Unipak input connector.
