SA1

Stereo Power Amp

The Stereo Power Amp is a precision power amplifier capable of delivering up to 1.5 Watts per channel to a pair of speakers or 3.0 Watts to a single speaker in ganged output mode. The SA1 is a stereo device with excellent channel separation and low signal distortion and noise. It has a flat frequency response from 50 Hz to 200 kHz. The output gain can be set between 0 and -27 dB in 3 dB steps.
