Installation
Mounting the equalizer
The EQ1208 is designed to be
installed to the underside of your
vehicle dashboard or other similar
surface using the screws and brackets
provided. Install the unit securely,
according to the diagram below.
Before installing your new
equalizer, please become familiar with
all the information contained in this
manual.
Choose a mounting location where the
unit will not distract or otherwise
interfere with the driver’s ability to
control the vehicle.
Vehicle dashboard
Use only the installation parts and
hardware provided with the unit to
ensure proper installation. Using other
parts can cause malfunction and
possible damage to your
equalizer.
Avoid installing the unit in a location
which is subject to high temperatures,
direct sunlight, hot air from such
sources as heaters or exhaust lines,
or where it will be subject to contact
with dust, dirt, moisture or excessive
vibration.

Turning on the power
The EQ1208 has internal ON/OFF
circuitry which responds to turning ON
or OFF the head unit of your car audio
system. This requires that your head
unit have a remote turn-on lead
available on the rear panel (which most
head units have).
With this convenient remote turn-on/off
feature, you never have to worry about
turning off the power to the equalizer
when you shut off the audio system.
