The Hertz S8 DSP audio processor processes audio signals at a resolution of 96 kHz and 24 bit and is Hi-Res certified by JAS (Japan Audio Society). Its die-cast metal and composite construction is corrosion-resistant, while six high- or low-level analog inputs and a coaxial SPDIF digital input allow audio sources to be connected. The eight RCA analog outputs are controlled by a 32-bit DSP processor.

Settings are adjusted via a Bluetooth app on a smartphone, tablet, or computer. The app includes volume and subwoofer level controls, as well as options to select or load configuration files. Automatic turn-on and turn-off via the speaker inputs is also supported.
