Samson Servo 120 overview

  • 1Description

The Samson Servo 120 Power Amplifier is a stereo power amplifier that can be used for all types of recording applications, live performance or permanent installs. The amplifier provides "reference-class" audio performance and reliability in a compact, single rack space package.

The Servo 120 utilizes high current output power transistors and features an efficient bipolar circuit design that continuously keeps DC output during idling at or near 0 volts. This keeps idle speakers at their zero point. Thermal and overcurrent protection circuitry is provided, and the amplifier is convection cooled for silent operation, eliminating fan noise and the need for filter maintenance.

The Servo 120 provides balanced 1/4" TRS and RCA coaxial inputs and push-spring terminal outputs. Also included is a front-panel protection light, a headphone output, a speaker on/off switch, and 3-color LED meters.

A stereo power amplifier for recording, live music, and installation applications
Operates in both stereo or bridged mono
50 Watts per channel into 8 Ohms
Stable bipolar circuit design continuously keeps DC output during idling at or near 0 volts, preventing unnecessary power applications to minimize heat overload
Toroidal transformer power supply for high current and low profile
High-current output power transistors
Protection relay circuitry (linked to the DC offset circuitry) that prevents "thumps" when powering on or off
Smart Servo circuitry protection against overheating and overcurrent
