The AAT2 Base Station Transmitter features a signal-to-noise ratio of better than 58 dB for outstanding sound quality. A peak reading LED display allows at-a-glance audio level monitoring, and a fully balanced input XLR 3-pin connector that is selectable to line, mic, or 70.7 volt line, with attenuation control. The AAT2 operates on a crystal-controlled fixed frequency that can be selected from any one of 17 narrow-band frequencies in the 72-76 MHz FM band, providing enough power for use in a large facility.
This one is on 72.300 MHz
I have not tested it because I do not have a receiver but the meters work when I run audio through it. It looks like new and has the rack ears and power supply but is missing the antenna.
