Architects' and Engineers' Specifications
The receiver shall be a stationary diversity design with pilot tone, 1200 carrier frequencies that can be programmed within a 30 MHz wide subband and a rugged half-
rack case with backlit liquid crystal color display. The receiver shall provide indicators for audio and RF levels; diversity mode (A/B); transmitter battery status; name,
frequency, frequency group, and preset (country) name. The color of the backlighting shall change between green and red to indicate normal operation or display user-
selectable warning messages (low battery capacity, audio level, RF level, etc.). The receiver shall select intermodulation-free frequencies automatically from an
integrated frequency database arranged by local frequency allocations and provide an automatic function for finding dead spots. An infrared radiator shall transmit
setup parameter data to the transmitter. Rear panel BNC sockets shall allow either the supplied antennas or a complex antenna network to be connected to the
receiver. The squelch threshold shall be adjustable between –80 and –100 dBm. The receiver's audio bandwidth shall be 35 Hz to 20 kHz; S/N 120 dB(A); THD <0.3%
at 1 kHz. Audio outputs shall comprise a balanced 3-pin XLR output switchable to –30 dB or 0 dB and an unbalanced 1/4" TS jack. The receiver shall provide a
lockable DC input for the supplied 12 V DC power supply. The receiver shall measure 200 x 44 x 190 mm (W x D x H) and weigh 972 g. The receiver shall be the AKG
SR 470 or equivalent.
