Hertz Remote Control DRC HE
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).
Developed According to Specific Ergonomics
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.
Physical Specifications

Powered by bit Drive technology
The H8 DSP firmware, based upon Flash memory, can be updated at any time without having to disassemble the device from the system: the software checks on the available updates from the bit Drive portal (https://bitdrive.it) guiding the user through all of the upgrade phases.
USS technology
Thanks to the built-in USS technology (Universal Speakers Simulator), H8 DSP can also be correctly connected to head units with “speaker load detection” function that monitors the presence of a low-impedance load to enable the audio outputs.

Time Alignment
- Guided procedure for the speaker distance data entry with an automated calculation (distance to time) for each channel accurate time delays.
- “Fine-tuning” can also be manually applied (0.02 ms fine set).
Remote Control
- Master Volume, Subwoofer Volume, Balance and Fader controls, Input selection, Memory selection.
Memory

This is a great piece of gear. I have found the Audison/Hertz line of equipment to be top shelf equipment. The ease of use and intuitive software make this DSP a valuable tool in the toolbox. Line inputs and 8 Channels out gives a lot of options. Being able to do time correction, line levels, and full active solution in one box is very powerful. The installation instructions leave a bit to be desired. The DRC installation has no instructions. I had to look on a like Audison product to find out I was plugging it in backwards (It goes in one way much easier than the other. The other actually makes it work). There are also different products available for the Audison which is not available for the Hertz equipment even though its almost the exact same product. Like a plug with RCA ports already wired in if you have RCA cables. Would I trade this for anything else, no way! This box is very powerful and for the price provides all the features necessary for this build.
