Architect and Engineering Specifications
The wireless microphone system shall feature a true-diversity receiver with 42 MHz of available tuning bandwidth with a total
of 1,680 frequencies accessible in 25 kHz steps. The wireless microphone receiver must feature one balanced XLR output with a
max. output of +18 dBu, and one unbalanced ¼” output with a max. output of +12 dBu. The wireless microphone receiver must
feature two BNC antenna inputs, one for each receiver module in the true diversity system. The wireless microphone receiver
must feature a backlit display that displays AF and RF levels, battery telemetry from the transmitter, operating frequency, and
diversity switching information. The wireless microphone receiver must feature an automatic frequency scanning function that
utilizes twenty (20) banks of pre-coordinated frequencies that are free of intermodulation interference. The wireless microphone
receiver must also feature a user bank in order to store user defined frequencies. The wireless microphone transmitter must
operate on two 1.5V AA battery cells. The wireless microphone transmitter must have access to 1,680 frequencies tuned in 25
kHz steps across a defined 42 MHz bandwidth. The wireless microphone transmitter must feature a backlit display that displays
frequency information, AF level, battery level. The wireless microphone transmitter must transmit a pilot-tone squelch. The wire-
less microphone transmitter must have a specified RF output power of 30mW. The wireless microphone receiver must accept 12V
DC power via BNC antenna inputs.
