How an equalizer is used
The EQ1208 graphic equalizer
is a high-fidelity signal processor/preamplifier that allows you to
graphically view and individually control
a number of different frequency bands
in a stereophonic system.
It is intended for use in a car audio
system which includes amplifiers in
the signal path AFTER the equalizer,
and provides Front, Rear and Subwoofer LOW LEVEL outputs via RCA connectors.
This graphic equalizer consists of
several audio filters, each centered
at a specific frequency in the audio
range.The EQ1208 enables you to
cut or boost the output level by up
to 18dB as desired at the following
frequencies:
40Hz• 150Hz • 1k Hz • 20kHz
The EQ1208 also features a subwoofer channel with an independent
crossover control. The crossover can
be set from 30Hz to 250Hz. Any signal below the frequency setting will
be sent to the subwoofer outputs,
allowing you to optimize the sound
to suit your particular subwoofer setup. Use of the subwoofer channel is
optional.

Installation
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.
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.
Figure 1 Mounting the equalizer
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.
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.
