For the loud crowd

You can also set up the Stereophonic for 2-channel operation, powering a single high-performance speaker with 190 watts RMS each, while sending 229 watts to a sub. High- and low-pass filters, with steep 24 dB per octave slopes, let you fine-tune the signal to precisely match your particular speakers and subwoofer. The Stereophonic's subwoofer channel features a bass boost, so you can really pile it on if you want.

Features

Channel Configuration: The Stereo Phonic is a 3-channel amp; essentially a full range 2-channel amp and a mono subwoofer amp built into one chassis. The full range section is bridgeable, so the it can be configured as a 3-channel or 2-channel amplifier.

    • 4Ω: 65 watts RMS x 2-channels
    • 2Ω: 90 watts RMS x 2-channels
