R L (UNBALANCED 10KΩ/0dBM) RIGHT GROUND MAX S/N USE CLASS 2 WIRING MINIMUM LOAD IMPEDANCE 4 Ω +RIGHT ∞ LEFT LEFT+ RIGHT LEFT INPUTS (BALANCED 10KΩ/0dBM) The Servo 260 power amplifier is designed for fixed installations, recording and live performance use. Easily installed, this compact, 2-space rack-mount stereo power amplifier delivers 130 watts per channel into a 4 ohm load, over a bandwidth of 20 Hz to 50 kHz. The 260 features high-current output power transistors with a bipolar design and servo circuitry that continuously keeps DC output during idling at or near 0 volts. It also features balanced 1/4" Tip-Ring-Sleeve inputs as well as push-spring terminal outputs, front-panel clip, idle and protection lights and thermal and overcurrent protection circuitry. The Servo 260 is convection cooled for silent operation, eliminating both fan noise and the need for filter maintenance. Housed in a rugged steel chassis, the Servo 260 uses high-quality component to ensure safe, reliable performance in all applications. Contact: • Rack-mount stereo power amplifier (2-space). • 130 watts per channel into 4 ohms (stereo). • 20 Hz to 50 kHz frequency response. • Balanced 1/4″ TRS and unbalanced RCA inputs and pushspring terminal outputs. • 1/4″ and push-spring terminal outputs. • Turn-on muting to prevent speaker “thumps.” • Servo protection circuitry continuously keeps DC output during idling at or near 0 V (thus keeping idle speakers at their 0 point). • Protection circuitry against overheating and overcurrent. • High-current output power transistors. • Unique bipolar circuit design. • Front-panel clip, idle and protection lights. • Independent left- and right-channel input controls with 41-position detents. • Convection cooled (No Fan). • All-steel chassis with new black matte titanium finish and anodized aluminum heat sink.

It shall be passively cooled, and shall have internal short-circuit and thermal protection 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 turnon. 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 20 Hz to 50 kHz, 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 490 W (115 Vac) and 490 W (230/240 Vac). The dimensions shall allow for standard 19″ EIA rack mounting. It shall be 3.5″ (88 mm; 2 rack spaces) high and 9.5″ (240 mm) deep. Weight shall be 17.6 lb. (8 kg). The power amplifier shall carry a three--year warranty. The power amplifier shall be a SAMSON SERVO 260.
