    This unique 3-channel amplifier has two 65 watt RMS full-range front channels for mids and highs – plus a mono channel with up to 229 watts (2 ohms) for a subwoofer – allowing a complete audio system to be built using a single Stereophonic amplifier.

    Stereophonic offers exceptional dynamic range for the best possible sound reproduction from your RetroSound® audio system. The full-range channels have a high-pass crossover for use with full-range speakers. The mono channel has a low-pass crossover to fine tune the bass frequencies for use with a subwoofer.
