Servo 120 Features
The Samson Servo 120 Power Amplifier utilizes the latest technology in professional power amplifier
design. Here are some of its main features:
• Power to spare - Each channel delivers 60 watts of power into 4 ohms (or, in Bridge mode, 120 watts
into 8 ohms).
• Clean, crisp sound - Impressive audio specifications such as .01% THD, S/N of 105 dB, crosstalk of
75 dB, and frequency response of 3 Hz to 65 kHz guarantee ultra-clean sound quality in any live or
recording environment.
• Independent input level controls for each channel with 41-position detents.
• Five-segment LED meters for each channel continuously display power output levels and allow you
to correct for overloading (clipping) conditions.
• Front-panel Protection LED shows you at a glance overheating or faulty wiring conditions.
• Innovative front-panel Speaker on/off switch and dedicated headphone jack enables private cue
monitoring of the input signal.
• Both electronically balanced 1/4" TRS and unbalanced RCA-type input connector jacks are provided,
along with push-spring terminal output connectors.
• Convection cooling (no fan) makes for whisper-quiet operation even in critical listening environments
such as recording studios.
• 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 120 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 120 with a single power strip into which a mixer or
other audio devices are connected, without danger of damage to connected speakers.
• Toroidal transformer power supply.
• Rugged construction (an all-steel chassis with a titanium finish and a lightweight anodized aluminum
heat sink) makes the Servo 120 eminently roadworthy.
• Flexible design allows the Servo 120 to be used free-standing or, with the use of included rack ears,
mounted in any standard 19" rack (taking just a single rack space).
• Three-year warranty.
• Last but certainly not least, value. The Samson Servo 120 has been designed from the ground up to
deliver excellent yet affordable sound quality.
