ARCHITECT’S & ENGINEER’S	SERVO 4060 SPECIFICATIONS
SPECIFICATION

The power amplifier, being of four channels, shall deliver a minimum of 60 watts into loads of 4 ohms, or 120 watts into loads of 8 ohms when in the bridged mode, or 120 watts + 60 watts + 60 watts (one side bridged). It shall be passively cooled, and shall have inter- nal short-circuit and thermal protection circuitry. A pro- tection LED indicator shall activate and the power amplifi- er shall disconnect the amp loads 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 1/4″ Tip-Ring-Sleeve balanced phone connec- tors and unbalanced RCA gold-plated connectors. Outputs shall be on insulated binding post connectors.The front panel shall have 4 independent level controls, each with a level indicator, a master power switch and amplifier pro- tection LED.

The power amplifier shall have a frequency response of 10 Hz to 85 kHz (-3 dB), signal-to-noise equal to or greater than 103 dB and THD less than 0.03%. Total power consumed at full audio power shall be 360 W (120 Vac/60 Hz) and 395 W (220 Vac/50 Hz)). The dimensions shall allow for standard 19″ EIA rack mounting or 17.5″ (444 mm) wide without rack ears. It shall be 3.25″ (82.5 mm; 2 rack spaces) high and 10.75″ (273 mm) deep. Weight shall be 25 lb. (11.3kg). The power amplifier shall carry a three-year warranty.

The power amplifier shall be a SAMSON SERVO 4060.
