System Features
The Samson Servo Amplifier utilizes the latest technology in professional power
amplifier design. Here are some of its main features:
• The Servo-550 model delivers 275 watts (into 4 ohms) of power per side.
The Servo-260 model delivers 130 watts (into 4 ohms) of power per side.
The Servo-170 model delivers 85 watts (into 4 ohms) of power per side.
• Optimized for usage in professional and project recording studios as well as
live performance, the Servo Amplifier boasts specifications (such as 0.03%
THD, S/N of 103 dB, crosstalk of 83 dB, and frequency response of 20 Hz to
50 kHz) that ensure ultra-clean sound quality in any environment.
• Unique bipolar circuit design that continuously keeps DC output during idling
at or near 0 volts (thus keeping idle speakers at their 0 point). This serves to
minimize heat overload problems by effectively preventing the Servo
Amplifier from applying power when unnecessary.
• Protection relay circuitry (linked to the DC offset circuitry) that prevents
“thumps” when powering on or off. This means that you can use the Servo
Amplifier with a single power strip into which a mixer or other audio devices
are connected, without danger of damage to connected speakers.
• The incorporation of high-current output power transistors that provide
power to spare.
• Front-panel Clip, Idle and Protection lights that show you at a glance the
status of the Servo Amplifier. To help you avoid overload before it occurs,
the Clip light goes on whenever the input signal rises to a distortion level
above .03% THD.
• Independent left and right Channel Input controls, with 41-position detents.
• The Servo-550 provides electronically balanced 1/4" input connector jacks,
while the Servo-260 and Servo-170 provide both balanced 1/4" input
connector jacks and unbalanced RCA input jacks. All three models feature
unbalanced 1/4" output jacks as well as binding post (in the Servo-550) or
push-spring (in the Servo-260 and Servo-170) output connectors.
• Rugged construction (an all-steel chassis with a lightweight anodized
aluminum heat sink) makes the Servo Amplifier eminently roadworthy.
• Flexible design allows the Servo Amplifier to be used free-standing or
mounted in any standard 19" rack (the Servo-260 and Servo-170 models
take only two rack spaces, while the Servo-550 requires just three).
