LR-600
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 15 KHz, ± 3dB at 72 MHz, or of 50 Hz to 10 kHz, ± 3dB at 216 MHz. 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.
