|Architect's and Engineer's Specifications
The power amplifier being of two channels, shall deliver 465W into 8 ohms with both channels operating, or 625W into 4 ohms with both channels operating. The amplifier shall be capable of bridge-mode operation thereby providing 1000W RMS output into 8 ohms and supplying a 70-volt distribution system without output matching transformers. The amplifier shall have a thermal shutdown system to protect the power devices from over-temperature operation. This thermal protection system shall be self-resetting. A protection LED indicator shall activate and the amplifier shall shut down to protect against short circuits and excessive high frequencies at the outputs, DC offset present at the outputs, or an internal power supply fault. The amplifier shall have slow start up and muted inputs of turn-on. The amplifier shall have a voltage gain of 32dB. Noise shall be at least 105dB below 53Vrms, A-Weighted, from 20Hz to 20kHz. Total harmonic distortion shall be less that 0.5% and inter modulation distortion shall be less than 0.1%. The front panel controls shall consist of independent level controls for left and right channels, a master power switch and a sequential operation switch. The dimensions shall allow for standard 19" EIA rack mounting. It shall be 3.5" high and 10.75" deep. The amplifier shall weigh 11 pounds. The power requirements shall be 120V, 60Hz, 1500W. The frequency response shall be +0, -3dB at 3Hz and 80kHz. The power amplifier shall be CARVER PT-1250.
