Specifications
Architectural Specifications
The FM speaker/receiver shall be capable of receiving on 57 wide and narrow band channels. The
speaker/receiver shall be have 10 watts output power and have a frequency response of 50Hz to 15KHz, ±
3dB at 72MHz, or of 50Hz to 10kHz, ± 3dB at 216MHz. The signal to noise ratio shall be 80dB or greater.
The device shall have an adjustable squelch and three-band equalizer. The device will incorporate a backlit
LCD Display that indicates channel and RF signal strength, as well as be used for channel selection
programming. The unit shall be programmable to display only used channels. It shall also incorporate an
electronically lockable volume and channel controls. Controls should be found on the top and rear of the
unit. The device shall incorporate a power supply (120VAC, 60Hz, 43 Watts), with output DC 12V 2500
mA tip negative. It will alternately use an internal battery pack using eight AA alkaline or NiMH
Rechargeable batteries and include recharging components for said NiMH batteries. The speaker should
have a minimum SPL of 110dB (±3dB). An included bracket will be able to be used as a handle for carrying,
or be adjustable up to 360 degrees around the unit for mounting. The Listen LR-600 is specified.
