Samson Servo 550 - Manual

• Rack-mount stereo power amplifier (3-space).
• 275 watts per channel into 4 ohms (stereo).
• 550 watts into 8 ohms (mono-bridged).
• 20 Hz to 50 kHz frequency response.
• Electronically balanced 1/4" TRS inputs.
• 1/4" and binding post outputs.
• Turn-on muting to prevent speaker “thumps.”
• Servo protection circuitry continuously keeps DC
output during idling at or near 0 volts (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
lightweight anodized aluminum heat sink.

POWER
The Servo 550 excels in live performance use,
recording studios and permanent installations. Easy to
install, this 3-space rack-mount stereo power amplifier
(which can also be used in bridged mono mode) delivers
275 watts per channel into a 4 ohm load (in bridged
mono mode, 550 watts into 8 ohms), over a bandwidth
of 20 Hz to 50 kHz. It utilizes high-current output power
transistors and a unique bipolar circuit design that contin-
uously keeps DC output during idling at or near 0 volts.
The Servo 550 also features balanced 1/4" Tip-Ring-Sleeve
inputs and both 1/4
″
and binding post terminal outputs,
front-panel clip, idle and protection lights plus thermal
and overcurrent protection circuitry. The Servo 550 is con-
vection cooled for silent operation, eliminating fan noise
and the need for filter maintenance. Built rugged with a
solid steel chassis, the Servo 550 is designed for reliable per-
formance over the long haul.
