    This powerful 5-channel amplifier has four 65 watt RMS full-range channels for mids and highs – plus a mono channel with up to 330 watts (2 ohms) for a subwoofer – allowing a complete audio system to be built using a single Technophonic amplifier.

Technophonic comes with a wired remote gain control module that allows you to adjust the bass output on the fly.

    Technophonic offers exceptional dynamic range for the best possible sound reproduction from your RetroSound audio system.
