The ultra-compact S8 DSP is the perfect solution for integrating any OEM source into any audio upgrade project for cars, motorcycles, and boats! S8 DSP is a distilled essence of technology at the service of the highest audio quality in a corrosion-free case cast in metal and composite materials.
S8 DSP processes the audio signal with 96 kHz / 24-bit resolution and has obtained the Hi-Res certification from the JAS (Japan Audio Society), an acknowledgment that certifies the extreme level of audio performance achieved.
The powerful 32-bit DSP manages 6 high/low-level analog input channels, one digital coaxial input, and 8 output channels, offering maximum freedom of configuration to the specialist. The SPDIF coaxial input is ideal for digital connection with a Hi-Res player, a solution that allows for maximum listening quality. For each of the eight output channels we have a level control, the 15-pole 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.
