S8 DSP

Digital Interface Processor

Hertz S8 DSP is the perfect solution for integrating any OEM system to your car, motorcycle, and boat! A distilled essence of technology at the service of the highest audio quality in a corrosion-free case cast in metal and composite materials

The S8 DSP process has obtained the HI-Res certification from the Japan Audio Society - which acknowledges the extreme level of audio performance achieved.

The 32-bit DSP offers maximum freedom of configuration to the specialist through the 6 high/low-level analog input channels, one digital coaxial input, and 8 output channels. The SPDIF coaxial input is best for digital connection with Hi-Res player, a solution that allows for maximum listening quality. For every one of the eight output channels we have a level of control, the 15-pol parametric equalizer, time delays, and crossover filter available. The 7-band parametric equalizer of the input signal allows obtaining a flat response from OEM sources, which often have an exaggerated emphasis on the low frequency.
