a315 digital stereo amplifier


provides 150 watts per channel at 8 ohms or 250 watts per channel at 4 ohms and features some of the latest technology from Wadia. Frequency Switching Transmission™ (FST) is an adaptive modulation design in the amplifier circuitry that assures full output power is delivered over the entire audio spectrum. Signal Surveyor™ monitors the output signal and stops amplification if unsafe levels of DC voltage are detected, thus protecting your speakers.

Overview

Both balanced and unbalanced inputs are available for connecting your other system components. Specially designed 5-way binding posts will securely hold your speaker wire. A trigger input and output makes it simple to control the power state of your entire system when the a315 is turned on/off.
