STEG DSP68-II

The STEG DSP68-II is a powerful 8-channel digital sound processor designed for precise sound optimization and maximum flexibility in the integration of modern car audio systems. With six input channels, eight separately configurable outputs, and high-quality Burr-Brown signal conversion, the DSP offers extensive options for customizing the sound system.

Thanks to its six RCA inputs and six high-level inputs, the processor can be used with both aftermarket radios and factory-installed audio systems. It also features an optical S/PDIF input and a coaxial digital input.

The powerful DSP software allows for easy adjustment of crossovers, time alignment, equalization, and signal routing. The built-in matrix mixer enables flexible distribution and summing of input signals. Up to five different sound profiles can be saved and recalled as needed.

Thanks to its compact design, automatic power-on function via high-level signals, and start-stop compatibility, the STEG DSP68-II is ideal for demanding OEM integrations and high-end car audio retrofits. An optional remote control and a separately available Bluetooth module expand the control options.
