The DSI-3 audio signal processor will allow you to precisely tune the acoustics of a vehicle’s audio system for maximum listening pleasure. With features like 6ch summable input, 12ch output, Bluetooth 5.0 audio streaming, and 31 band parametric EQ this DSP can easily handle the increased interfacing and tuning needs of today’s multi channel audio systems.

The DSI-3’s PC interface has an advanced tuning suite for easy system setup and the mobile user interface is compatible with Apple and Android for on the go tuning and control.
