Hertz H8 DSP 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 car compartment.
DIGITAL INTERFACE PROCESSOR
ANALOG AND DIGITAL INPUTS
Analog inputs.
The H8 DSP 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.
OUTPUTS
Digital input and analog outputs.
The H8 DSP features 8 PRE OUT analog outputs each of them including: a 31 band equalizer, a 66 step electronic crossover, LinkwitzRiley or Butterworth filters with selectable 6 – 24 dB adjustable slopes and digital time delay functions.

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.

DRC HE
Digital Remote
Control
The optional 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).

By configuring the UCS four position dip switch, simply
receiving a signal from an external device, the selection of
the Aux digital input and of the PC setup MEM A and MEM B
is enabled. For example the car seat belt sensor can be used
to activate the processor MEM B setup, optimized for both
passenger and driver.
DIGITAL INTERFACE PROCESSOR
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 Standard mode guarantees straightforward and simplified system management achieving great results with little effort: a guided
set-up procedure, according to the parameters assigned to the outputs, assists the user in setting up the crossovers and equalization
enabling the tuning of any system in just a few “clicks”.
With the Expert mode, the software provides the ability to freely access all the parameters for a totally customized tuning experience.
The software features a Context-sensitive Help, that the user can activate, opening a dynamic help window including detailed description
of its main functions.
The PC software is available in English, Italian, German, Russian, Chinese, Japanese, Korean. The user can select the language and the
change will be applied to the drop-down menus as well as to the Context Help messages. The number of available languages will
increase: once updates are available, they will be downloadable from the bit Drive portal (bitDrive.it).

H8 DSP Software
DIGITAL INTERFACE PROCESSOR
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 (http://bitdrive.it) guiding
the user through all of the upgrade phases.
Additionally, the user can manually force the update and
proceed with a safe installation which can be retrieved even
in case the update fails due to external accidental causes.
Connecting the H8 DSP to the Audison bit Tune, you
can automatically calibrate the basic parameters of the
processor (time alignment, equalization, levels, etc.), ensuring
an excellent level of acoustic performance. This phase also
includes the diagnosis of common connection “errors”
(channel inversion/phase, no signal on one channel/ cable,
etc.) to set the specialist free from “routine” work and allow
him to focus on the art of “fine-tuning”.
SIGNAL PROCESSING
The H8 DSP features a 32 bit DSP and 24 bit A/D and D/A
converters ensuring top level performance, as well as a powerful
microcontroller to manage, supervise and connect the system to
the PC software. Following the conversion from analog to digital or
starting in the digital domain using the S/PDIF digital inputs, the
H8 DSP provides the ability to:
1. automatically reconstruct a linear full-bandwidth stereo signal;
2. de-equalize the frequency response, to “flatten” any equalization
applied by default by OEM sources. This operation can be initiated
through a simple push button switch found on the device, without
the need for a PC;
3. reconstruct the signal, in case the system requires a centre
channel or subwoofer when the corresponding signals are not
available as input channels;
The user can configure the system via PC software.
Each channel can:
1. be activated, de-activated or phase inverted;
2. be filtered with a Linkwitz or Butterworth crossover alignment,
with adjustable slopes (6- 24 dB/Oct.), from 20 to 20,000 Hz cutoff frequencies, in Hi-Pass, Lo-Pass and separately configurable
slopes and frequencies on each side of a Band-Pass filter;
4. be acoustically time aligned with the other channels with up
to 15 milliseconds delay, in 0.02 Ms steps, corresponding to a
510 cm virtual loudspeaker “movement”. The user can adjust the
initial delay settings by following a guided on-screen procedure
for a consistent reconstruction of the sound stage. A manual
adjustment function is available for the delay “fine-tuning”;
5. adjust its output level to further tune the system’s overall
response.

GLOSSARY
H8 DSP:
digital interface processor used to elevate the acoustic performance of any Car Audio system.
DRC HE:
the optional DRC HE allows the user to choose between two “tuning” configurations pre-sets
created and saved using the software; select the source from the master, auxiliary and optical
digital inputs ; adjust main system functions (volume, balance, fader and subwoofer volume).
DSP:
Digital Signal Processor, a special microprocessor, featuring a specific internal structure, destined
for the continuous processing of data streaming.
32 bit:
the term “32 bit” represents the number of significant digits used in a sample representation. The
“32 bit” format is employed in high-performance DSPs. Other formats used to save digital format
signals: 16 bit (CD), 24 bit (Hi-Res audio files “liquid music”, DVD, Blu-ray).
44,1 ÷ 96kHz:
sampling frequency of S/PDIF digital signal. 44,1kHz: CD; 48,0kHz: Hi-Res audio files (liquid music),
DAT; 96kHz: Hi-Res audio files, DVD.
PCM:
Pulse Code Modulation, digital representation of an analog signal, with the total lack of compression,
thus the complete representation of the sound information.
FLAC:
lossless algorithm recognized as a standard for encoding high resolution liquid music. It allows the
user to save up to 50% of the space without any loss of audio quality and is ideal to free store your
entire music collection without any compression.
compressed digital audio signals. Compared to the PCM format, they remarkably reduce the
memory occupation with consequent sound quality deterioration.
S/PDIF:
standard used for the digital audio transmission over coaxial cable or optical fiber.
TOSLINK:
fiber Optical cable connection for S/PDIF signals.
