Memphis VIV68DSP 6-In/8-Out Digital Sound Processor

The Memphis VIV68DSP is a 6-input, 8-output digital sound processor for building a more precisely tuned vehicle audio system. It accepts factory-style speaker-level signals as well as RCA, optical, and Bluetooth audio sources. Its processing tools help shape a system’s signal before it reaches external amplifiers.

This processor is intended for enthusiasts upgrading a factory or aftermarket system that needs more control than a head unit alone can provide. Signal sensing, input summing, and adjustable channel routing support integration into a range of system layouts. Eight low-level output channels provide flexibility for active front stages, rear speakers, and subwoofer channels.

The VIV68DSP gives each output channel an independent 31-band equalizer, crossover filtering, phase selection, and time alignment. This lets the installer balance tonal response, define speaker operating ranges, and align arrival times at the listening position. The result is a more deliberate, system-specific tuning approach rather than one global adjustment.

Its app-based control platform works with PC, iOS, and Android devices, while wireless connectivity supports control and audio streaming. Crossover selection includes Butterworth, Linkwitz-Riley, and Bessel filter characteristics, with adjustable frequency, slope, and output settings. Six preset memories make it practical to save tuned configurations for later recall.

The VIV68DSP fits between the source unit and external amplifiers in a multi-amplifier upgrade path. It can retain an OEM radio through its six-channel high-level input capability or work with aftermarket RCA and optical sources. A wired remote connection supports preset recall and level control, with channels 7 and 8 assigned by default for remote subwoofer-level control.

Key Features

• 6 Inputs, 8 Outputs: Supports flexible routing for complex amplified audio systems.
• 31-Band EQ Per Channel: Allows detailed tonal adjustment on every output.
• Independent Crossovers: Sets high-pass or low-pass filtering per channel.
• Time Alignment: Adjusts output delay for a more coherent listening position.
• Multiple Source Inputs: Accommodates high-level, RCA, optical, and Bluetooth sources.
• App-Based Tuning: Provides setup control from PC, iOS, or Android devices.

Design & Installation

The VIV68DSP uses a connection layout with six speaker-level inputs, six RCA inputs, an optical input, eight RCA outputs, power terminals, a remote-control connector, Bluetooth antenna connection, PC control port, and RGB LED output. Its output channels are individually configurable through the DSP software. Ground-isolation jumpers are provided and should only be adjusted with power switched off.

Install the processor between the source unit and external amplifiers, using the input type appropriate for the vehicle’s radio or audio source. It requires a DC 8.5V to 16.5V supply, ground, and either a 12V remote trigger or signal sensing at inputs 1 and 2; the manual specifies an in-line 3A fuse on the +12V line. For system tuning, disable amplifier crossover and bass-boost processing where possible so the DSP can manage equalization and crossover duties.
