PM-1400 Architects and Engineers Specifications The power amplifier being of two channels, shall deliver 475W into 8? per channel with both channels operating, and 700W into 4 ? per channel with both channels operating. The amplifier shall be capable of bridged-mono operation thereby providing 1400W RMS output into 8 ?. The amplifier shall be capable of parallel-mono operation for low impedance operation, thereby providing 900W RMS output into 4 ?. Each channel shall be equipped with compression circuitry that electronically senses the onset of clipping and engages a specially-designed circuit which virtually eliminates the possibility of driving the amplifier into distortion. A switch shall be provided to defeat The Clipping Eliminator circuit from both the channels. Internal components shall be fan cooled. The fan shall operate at 2 speeds, the speed being determined by internal operating temperatures. 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 illuminate and electronically activated relays shall disconnect the speaker outputs to protect against over temperature, short circuits, DC offset present at the outputs or an internal power supply fault. The amplifier shall provide delayed activation of the speaker output relays at turn-off. The amplifier shall have a voltage gain of 36.7dB (0.0775V RMS sensitivity), with a removable jumper on each channel to change the gain to 20.7B (1.5V RMS sensitivity). Noise shall be at least 100 dB below 700W/4 ? A-Weighted. Total harmonic distortion shall be less that 0.1% at 1.5V sensitivity, 0.2% at 0.775V sensitivity. The front panel controls shall consist of a master power switch and a fuse-holder containing a replicable 15A slo-blo fuse. Front panel indicators shall include a Ready LED which shall illuminate red when a protection circuit is activated, five yellow Signal present LEDs and a red Clip/Protect LED for ea
