Fine Tuning: Signal Processing - Hifonics ODIN 2K Product Manual

A ticking or whine that changes with engine RPM:
16
1. This problem could be caused by radiation pickup of RCA cables too near to a fuel pump or a distributor,
for instance. Relocate cables to resolve this issue.
2. Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory
wiring for ground.
3. Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a
supply from the in-dash wiring/fusebox.
A constant whine:
This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing
oscillations in the system.
1. Check all connections, especially for good grounds.
2. Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.
3. RCA cables are notorious for their problematic nature, so check that these are good, in particular the
shield connections.

Every audio system can benefit from being fine-tuned. After the amplifiers, speakers and subwoofers have
been dialed in, the next step is fine tuning with external signal processing. Amplifiers have limited signal
processing designed for the specific speakers and subwoofers that are connected to those amplifiers. For the
ultimate control of equalization in a vehicle, consider some of these Hifonics signal processors to continue
improving the sound of your system.

Most car audio enthusiasts are very happy to install a system, set it and forget it. However, there are a few
of us listeners – you know who you are – who are never satisfied. Especially if you have a wide variety of
musical styles you enjoy. You have noticed how a piece of music from one record company or one artist can
sound completely different than the next. One might need a quick adjustment to the bass, while another might
need to have the high end frequencies toned down to keep from ripping your face off. That requires control.
Hifonics Signal Processors put control at your fingertips. Wherever you and/or your installer can install the
remote controls included with several of these products, you will be able to make quick adjustments or
tweaks, to the system to reflect the great and not so great recordings you play through your system.

Shaping the sound is a critical process in the fine tuning of a high performance system. Creating a
boost at certain frequencies or dip where frequencies might be too strong is going to require real control
of equalization.
Here is a quick rundown of Hifonics processors. For more information, check out the website.
HDbr - Hifonics Digital bass restoration
The HDBR contains a BASS DRIVER circuit that accurately
recreates and injects Low Frequency information back into
the signal path. What that means in everyday terms is that
the HDBR will give more bass impact to your best high
quality digital media or your lowest quality recordings or
worst radio station reception.
The HDBR has a unique equalization circuit that contours the restored bass according to your desires using
the variable shaping controls.
We have also included a dash mount remote control with a Bass Maxximizer Indicator that becomes brighter
as you maximize the restoration or dimmer as you back off on enhancements allowing you to be in constant
control of the restoration level.
