The ATW-R2100a is a True Diversity UHF wireless receiver operating in the UHF bands of 656.125-678.500MHz or 487.125-506.500MHz. The 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. A pre-coordinated integral channel plan allows for simultaneous operation of any of the 10 channels in a given location. The flexibility in programming both the receiver and transmitters eliminates confusing frequency groups and other frequency coordination problems. A two-position switch turns on/off 12V AC antenna power for use with powered antennas or accessories.

Its advanced Tone Lock adjustable squelch system fights interference. A high-sensitivity dual IF design using true diversity operation with silent automatic switching provides dropout-free performance. The front panel LCD receiver display provides continuous indication of transmitter RF signal strength, selection of internal dual (True Diversity) receiving sections (A&B), along with the audio modulation level of the received signal. Both balanced XLR-type and unbalanced 1/4" output connections with output gain adjustments are located on the rear panel. The XLR-type output includes a ground lift switch to prevent ground loops. Features not often found in other receivers include a metal receiver construction, detachable wave receiver antennas, AC or 12-18V DC operation, front panel power switch, and included rackmount kit.

      Comments about Audio-Technica ATW-R2100a 2000 Series Diversity Receiver:

      I ordered this receiver to use in our church. Our sanctuary isn't too big (seats about 175 people). The receiver was shipped in a timely manner, was easy to set up, and fits our needs in our congregation.
