The D-20 amplifier offers greater output power than the D-10. Its modern Class AB bipolar design delivering the cleanest sound available coupled with ultra-high standards of reliability. Capable of handling 2 ohm loads, the D-20 control and protection circuitry continuously checks for fault conditions including shorted outputs, DC on outputs, excessive temperature, and component failure. If such an event occurs the outputs are disconnected, saving expensive driver repair bills. The D-20’s sophisticated side chain limiters prevent distortion and speaker damage but are out-of-circuit until the onset of clipping. The control circuitry provides full protection against inrush current limiting with delayed turn-on. Low noise variable-speed fans are utilized to minimize mechanical noise, making the D Series an ideal choice for theaters, auditoriums.
