Product Description

The ATW-R3100b frequency-agile true diversity UHF wireless receiver sets a new standard for audio and RF performance. With a large operating range and superb noise specifications, the 3000 Series provides the audio quality and reliability necessary for the high quality sound systems of today.

Automatic frequency scanning eliminates the need for searching for clear channels and automatically selects the most appropriate frequency for the area in which the wireless is operating. 25 kHz frequency spacing enables the system to easily find an open frequency in crowded RF environments, while nine pre-coordinated frequency scan groups simplify selection of usable frequencies in a multi-channel wireless system. The flexibility in programming both the receiver and transmitter allows the customizing ability for this wireless system to meet virtually any application. Features not often found in other receivers include high-pass filter, meter hold function, adjustable squelch, selectable power/mute on transmitters, lock functions for operational safety, and control of input sensitivity.

Designed to operate from AC or 12–18V DC, the receiver incorporates rear-panel connections for balanced XLR and unbalanced 1/4" outputs with adjustable gain along detachable BNC 1/4" wave antennas are also included. Switchable 12V DC antenna power is available on the BNC-type connectors for powered antenna accessories. The receiver is half-width for a standard 1U 19" rack-mount and includes rack-mount adapters.
