The Hertz H8 HSP DRC is a 4 channel and optical audio in with 8 channel output digital signal processor. Perfect for use in vehicles where sound quality is a must.

Hertz H8 DSP car audio processor is capable of interfacing with any analog and/or digital source, transforming ordinary “audio” into a high-performance integrated system. The simple and intuitive computer software ensures a wide array of adjustments to improve the acoustic response of a complex environment like the inside of a car.

It provides 7 signal inputs with a variety of connection options: four high-level inputs, also accepting low-level pre-amplified signals; a stereo auxiliary input and an optical digital input accepting signals at a sample rate up to 96/24 bit.

The optical digital input (selectable through the DRC HE remote control and from the “Optical / AUX select” terminal) nullifies interferences and signal deteriorations also by-passing the analog signals A/D conversion stages.

 Thanks to the configuration Wizard provided by the software during the set-up, the H8 DSP can automatically sum up multiple filtered channels (for instance, woofer plus tweeter), “flatten” the OEM source equalized response curve and reconstruct a centre, rear and/or subwoofer channel with a simple stereo input.

By reading the test track on the CD provided, the H8 DSP recreates a full-bandwidth signal, with a flat frequency response and released after processing for an outstanding sound quality.

Developed according to specific ergonomics criteria required by the Car Audio industry, the PC software facilitates direct access to all the available functions for the signal treatment, providing immediate results, as well as extreme operational accuracy. 

Setting the parameters of each input single channel, adjusting the delays according to the listening position, tuning the crossovers and equalizers for each output channel; these are just some of the operations that can be managed by the PC software based on Windows platform (XP, Vista, 7,8, 10) to be used in Standard or Expert mode. 

The provided DRC HE enables the main system control without the use of a PC. Thanks to this device, installed in an ergonomic position within the car dashboard, the user can: choose between two “tuning” configurations previously saved using the PC software; select the source from the master, auxiliary and optical digital inputs ; adjust main system functions (volume, balance, fader and subwoofer volume).
