Power Amplifier

Ideal for powering near-field monitors or installation sound, the new Servo 120a delivers "reference-class" audio performance and reliability in a compact package. This single-space rackmount stereo power amplifier delivers 60 watts per channel into 4 ohms, or 120 watts into 8 ohms in bridge mode. The intuitive front panel features controls and indicators including a power switch, independent left and right channel input level controls, 10-segment LED meters, a protection LED, and a convenient headphone jack and speaker on/off switch for private cue monitoring. Perfect for recording studios, sound reinforcement, stage monitoring, and home theater applications, the 120a's bipolar design and toroidal transformer power supply ensure reliability.
