VIV68DSP

The VIV68DSP is a six input, eight output digital signal processor for systems that need real tuning rather than a head unit tone control. It works with virtually any source, including a factory radio, thanks to high level inputs, signal sensing turn-on, and channel summing that rebuilds a full range signal from a factory-processed one.

Each of the eight outputs gets its own 31 band equalizer, time delay, and crossover with 12 or 24 dB per octave slopes. That is enough control to align a three-way front stage with a subwoofer, pull down a peak caused by a door panel, and time align drivers so the stage sits centered instead of in the passenger door. A Toslink optical input accepts a digital source directly, and wireless streaming plays audio into the processor without a cable.

Tuning happens in the app on PC, iOS, or Android, so adjustments get made from the seat where you actually hear them. The included remote handles preset recall and level control, letting you switch between settings tuned for daily listening, demos, or a full car.

The numbers back it up: 110 dB active range, 100 dB signal to noise, and 0.02% THD across a 10Hz to 20kHz response. For any build where the vehicle dictates speaker placement, this processor is what makes the result sound intentional.
