$840 · Amplifier Carver PT-1800, 1100 Watts / CH

This power house amplifier has low usage and is in very good condition. The price is firm 600W power/ch at 8-ohm 900W power/ch at 4-ohm 1100W power/ch at 2-ohm Connections: Input: XLR, barrier strip Output: 5-way binding posts, 2 sets/channel The amplifier has two completely independent power supplies, one per channel and provides independent operation with the exception of the series (bridge-mono) mono and the parallel mono operation. The amplifier has a thermal shutdown system to protect from over-temperature operation and is self-resetting. The amplifier built-in input limiting to protect the output devices against short circuits or against non-musical excessive high frequency signals. Each channel can independently shut down to protect against DC offset present at the outputs. The amplifier has slow start up and muted inputs on turn-on preventing tripping breakers or having loud pop in the speakers. The amplifier has a voltage gain of 32dB. Noise shall be at least -100dB below 600 W/8 ohms, Total harmonic distortion is less then 0.5% and inter modulation distortion is then 0.1%. The front panel has one volume control per channel, one master and one sequence switch. The amplifier provides input configuration switches to allow in rack selection of dual mono, series mono, clip eliminator and 3-pin polarity configuration. A cooling fan operates on two speeds determined by the heat sink temperature. The amplifier weight 46 pounds. The input current requirements per channel for a 900W output in to 4 ohms is 17 amps at 120V, 60Hz. * Fully modular dual monaural design. * High efficiency (50% input to output). * Positive locking detachable dual AC line cords. * Compact - only 12.75" deep. * Rugged, quiet, 100 CFM thermally controlled cooling system. * Compression circuit * Remote sequential power on/off feature. * Clipping eliminator circuit.
