Architects and Engineers Specifications
The wireless system shall operate over a 30 MHz UHF frequency range
in one of 6 bands from 680 to 863 MHz, with a wide range of possible
frequency settings. The wireless microphone system shall incorporate
factory-optimized sets of both transmission and receiving frequency
modules that are programmed into both transmitters and receivers. Each
frequency set shall comprise a 30 MHz UHF band and offer up to 1,200
discrete operating frequencies within that band, with transmitter power
not exceeding 50 milliwatts. Both handheld and bodypack type trans-
mitters shall be provided. The bodypack transmitter shall accommodate
both microphone and line level inputs. The transmitters shall operate
with a companding system that is complemented by the receiver,
providing an A-weighted system dynamic range in excess of 120 dB.
The transmitters shall indicate input overload via an LED indicator and
on a backlit display battery lifetime shall be displayed in hours as well
as the transmitting frequency. Handheld transmitters shall have a
maximum diameter of 39 mm and a length, including antenna, no greater
that 239 mm. The wireless microphone system shall be the AKG
Acoustics Model WMS 4000.
