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
>Independent input level controls for each channel with

>Unique bipolar circuit design that continuously keeps DC output during idling at or near 0 volts (thus keeping idle speakers at their zero point). This serves to minimize heat overload problems by effectively preventing the Servo 120a 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 120a with a single power strip into which a mixer or other audio devices are connected, without danger of damage to connected speakers.
