Receiver

The wireless receiver uses two dipole antennas to help provide extended operating range and reliable reception. Four selectable VHF frequencies allow you to choose the appropriate operating channel for your environment.

The front panel includes LED indicators for channel, RF signal, and AF peak, while the rear panel provides convenient controls and connections including volume and squelch controls, balanced XLR output, and unbalanced 1/4" output.

An integrated power cord hook helps secure the DC power connection and prevent accidental disconnection.

Bodypack Transmitter

The compact Unipak bodypack transmitter operates on two AA batteries and includes adjustable microphone and instrument input trim, channel-selection DIP switches, a Power/Mute button, and a Unipak input connector.

The included Audio-Technica PRO 8HEcW headworn microphone provides a hands-free microphone solution, making this system particularly well suited for presentations, teaching, public speaking, live performance, and other applications where the user needs both hands free.

Squelch Control

The receiver's adjustable squelch control sets the threshold for the incoming radio signal. If the wireless signal drops below the selected threshold, the receiver automatically mutes the audio output, helping reduce unwanted radio interference and background noise from reaching the connected sound system.
