a102 digital stereo amplifier


provides 50 watts per channel at 8 ohms or 80 watts per channel at 4 ohms. With an electronic switching design, our new generation of amplifiers are able to deliver massive amounts of power directly to your speakers with very little energy wasted in heat dissipation. They do away with the necessity for large cooling fins or noisy fans often found in other high power amplifiers. The result is a greener, compact and energy efficient amplifier.
As with all Wadia digital amplifiers, the a102 produces exceptional sound quality and performance. It features Wadia’s new Signal Surveyor™ technology, which monitors the amplifier’s output signal and stops amplification if unsafe levels of DC voltage are .
