The DD Audio DSI-3 is a powerful 12-channel DSP audio signal processor for car audio systems. The device can be adjusted via Bluetooth with iOS, Android, and PC applications (USB-B). Bluetooth 5.0 also enables audio streaming.
The DSI-3 is a significantly improved version of its predecessor, the DSI-2: the processor is 6x faster, the number of output channels is doubled, and the EQ has been expanded to a 31-band parametric equalizer.
Signal In and Out
The signal can be input at either speaker level or line level (RCA/optical). The trigger input is selectable: 12V remote, speaker-level signal, or RCA level. The summation of incoming signals allows for the construction of a full audio range signal even if the signal is taken after crossovers — a very useful feature in original car audio systems.
Accessory
A remote control is available separately for volume and preset changes: DD Audio DSI-3R remote control.
