WADIA a315 Series Power Amplifier Trade-In
The Wadia a315 digital stereo amplifier provides 150 watts per channel at 8 ohms or 250 watts per channel at 4 ohms. It shares the same sleek, modern industrial design as the 321 decoding computer, making it a perfect amp to use with the 321. Both will blend nicely with virtually any room styling.
The a315 features some of the latest technology from Wadia. Frequency Switching Transmission™ (FST), an adaptive modulation design, reduces distortion at any power level over the entire audio spectrum. Using a feedback technique, it makes real time micro-adjustments to the switching carrier frequency to improve linearity, thereby significantly reducing audio distortion. The higher the amplifier’s power output, the greater observed reduction in distortion. Signal Surveyor™ monitors the output signal and stops amplification if unsafe levels of DC voltage are detected, thus protecting your speakers.
