ARCHITECT’S & ENGINEER’S

SPECIFICATION

The power amplifier shall be capable of stereo, mono bridged or parallel (daisy chain) operation. In stereo mode, it shall deliver a minimum of 750 watts into loads of 4 ohms each with both channels operating. In mono bridge mode, it shall deliver a minimum of 1500 watts into an 8 ohm load. It shall be cooled by two temperature sensitive speed-con- trolled fans, and shall have internal short-circuit and thermal protection circuitry. A protection LED indicator shall acti- vate and the power amplifier shall shut down to protect against short circuits, overheating, severe overcurrent con- ditions or DC offset present at the outputs. The power amplifier shall have slow start-up and muted inputs on turn- on. Inputs shall be on XLR and locking balanced 1/4″ tip- ring-sleeve connectors. Outputs shall be on Banana jack and Speakon™ connectors. The front panel shall have indepen- dent level controls for left and right channels, a master power switch and LED indicators for power, clip, -20dB, -40dB and amplifier protection.

The power amplifier shall have a frequency response of 9 Hz to 42 kHz, signal-to-noise equal to or greater than 105 dB and THD less than 0.03%. The dimensions shall allow for standard 19″ EIA rack mounting. It shall be 5.25″ (133.35 mm; 3 rack spaces) high and 9.75″ (247 mm) deep. Weight shall be 48 lb. (21.8 kg). The power amplifier shall carry a three-year warranty.

The power amplifier shall be a SAMSON S1500.
