pt1800 Architects’ and Engineers’ Specifications The power amplifier being of two channels, shall deliver 600 W into 8Ω per channel, 900 W into 4Ω per channel. The amplifier shall be capable of providing 650 W per channel into a 70 volt distribution system without the need for step-up transformers. The amplifier being of two completely independent power supplies per channel shall be capable of operating from separate AC branch circuits and to provide independent operation with the exception of the series (bridge-mono) mono and the parallel mono operation. The amplifier shall be capable of series bridge-mono operation thereby providing 1800 W RMS output into 8Ω. The amplifier shall have a thermal shutdown system to protect the power devices from overtemperature operation. This thermal protection system shall be selfresetting. The amplifier shall provide input limiting to protect the output devices against short circuits or against non-musical excessive high frequency signals. Each amplifier shall independently shut down to protect against DC offset present at the outputs, or an internal power supply fault. The amplifier shall have slow start-up and muted inputs on turn-on. The amplifier shall have a voltage gain of 32 dB. Noise shall be at least -100 dB below 900 W/4Ω, A-weighted, from 20Hz-20kHz. Total harmonic distortion shall be less than 0.5% and intermodulation distortion shall be less than 0.1%. The frequency response shall be less than ±0.5 dB, 20Hz-20kHz. The front panel controls shall consist of per channel: one level control, one master power switch and one sequence switch. The rear panel connectors

shall consist of per channel: 3 input barrier terminals, one 3-pin locking input connector, two sets of dual bind post output connectors, two barrier sequence terminals and one positive locking AC power cord. The amplifier shall provide input configuration switches to allow in-rack selection of dual mono, series mono, clip eliminator and 3-pin polarity configuration. A cooling fan with removable filter shall operate on two speeds that is determined by the heat sink temperature. The dimensions shall allow for standard 19” EIA rack mounting. It shall be 5.25” high and 12.75” deep. The amplifier shall weigh 46 pounds. The maximum input current requirements per channel for a 900 W output into 4Ω shall be 17 amps at 120V, 60Hz. The power amplifier shall be a CARVER Professional pt1800.
