The DSI-3 audio signal processor is significantly improved over the previous DSI-2 with multiple upgrades based on direct customer feedback. Improvements were made in processing power, input channels, output channels, wireless connectivity, installation capabilities, OEM integration, and EQ capability. 

Although the feature upgrades were substantial, the size remained small with an increase of only 1.5″ in the chassis length.

The DD Audio DSI-3 is a DSP that can be controlled via iOS devices or through a computer.

Signal inputs of both high and low level. 

• The remote system is automatically selected-high, auto-low, or cable. This is an excellent choice for use with OEM head units. Or in any system where a user-friendly DSP is required.

Inputs have summing capability. 

• Some OEM systems do not have full-range signals on one pair of wires, so signal summing helps you get a full-range signal.

It can also be configured via a computer (USB-B cable) or via iOS devices using Bluetooth (the DSI-3 has built-in Bluetooth).
