The Audio-Technica System 9 VHF Wireless Unipak System with Omnidirectional Lavalier Microphone is designed for live sound reinforcement applications. The system consists of a wireless VHF receiver, a bodypack transmitter, and an omnidirectional lavalier microphone. The receiver utilizes two dipole antennas for extended range, and allows you to select your VHF transmission frequency from 169.505, 170.245, 171.045, or 171.905 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 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.
Four Selectable VHF Transmission Frequencies
Select from 169.505, 170.245, 171.045, 171.905 MHz
Dipole Antenna for Extended Range
The receiver utilizes two antennas to improve the range of the system
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
