HERTZ S8 DSP sound processor



The ultra-compact S8 DSP sound processor is the ideal solution for building an audio system in a car, motorcycle or boat, even using OEM signal sources. The S8 DSP processes audio at 96 kHz / 24-bit resolution and is Hi-Res certified by JAS (Japan Audio Society).

The powerful 32-bit DSP processes signals from six analog high/low inputs, a digital coax input, and features eight output channels for maximum tuning flexibility. The SPDIF coaxial input is ideal for digital connection to a Hi-Res player for maximum listening quality. Each of the eight output channels has a level control, 15-band parametric equalizer, time delay and crossover. A 7-band parametric EQ for the input signal lets you correct for the signal from OEM sources.

The EQ range is +/-12dB in 0.1dB increments, with center frequency and Q-factor adjustments. Butterworth, Linkwitz-Riley, and Bessel filters are available in the crossover with a slope from 6 to 30 dB/oct, and the cutoff frequency is set between 20 Hz and 20 kHz. The line outputs are 4 V voltage at k.n.i. max 0.05%, signal-to-noise ratio 95 dBA.

For configuration and subsequent control an application on a smartphone with Bluetooth connection is used. (Configurator” and “DRC” modes). Requires Android version 7 or higher, iOS requires version 12 or higher. There are 4 presets in the settings, which use external switches to select. A separate control signal is provided for analog or digital input selection.

The power supply voltage is 7-20 V with a current of up to 1 A, automatic activation from the constant component of the high level signal, Remote signal input and output is provided. The processor measures 130 x 33.8 x 88.3 mm and weighs 0.66 kg.
