ARCHITECT’S & ENGINEER’S

SPECIFICATION

The power amplifier shall be capable of stereo or mono bridged operation. In stereo mode, it shall deliver a minimum of 52 W into loads of 8 ohms each with both chan- nels operating, or 60 W into loads of 4 ohms each with both channels operating. In mono bridge mode, it shall deliver a minimum of 120 W into an 8 ohm load. It shall be passively cooled, and shall have internal short-circuit and thermal pro- tection circuitry. A protection LED indicator shall activate and the power amplifier shall shut down to protect against short circuits, overheating, severe overcurrent conditions 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 balanced 1/4″ tip-ring-sleeve connectors and outputs shall be on 1/4″ phone connectors and on push- spring terminals. The front panel shall have independent level controls for left and right channels, a master power switch and LED indicators for clip, idle and amplifier protection.

The power amplifier shall have a frequency response of less than 10 Hz to 100 kHz, signal-to-noise equal to or greater than 103 dB and THD less than 0.5%. Total power consumed at full audio power shall be 240 W (120 Vac) and 975 W (220 Vac). The dimensions shall allow for stan- dard 19″ EIA rack mounting. It shall be 1.75″ (44 mm; 1 rack space) high and 11.5″ (292 mm) deep. Weight shall be

15.6lb. (7 kg). The power amplifier shall carry a three-year warranty.

The power amplifier shall be a SAMSON SERVO 120.
