A graphic equalizer is a high-fidelity audio control that dlows you
to graphically view and individuallycontrol a number of different
frequency bands in a stereophonic system.
A typical graphic equalizer consists of several audlo filters, each
centwed at: a specific frequency in the audio range-The B3
AVA-I 204 and AVA-1404 equalizers enable you to cut or s"a octst the
output level by up to 12dR as desired at the following frequencies:
ti0I.t~ . 150Hz 400Hz r 1 kHz
3kHz = 6kHz 15kHz
The AVA-1204 and AVA-1404 have internal ON/OFF circuitty which
responds to turning ON or OFF the head unit of your car audio
system. This requires that your head unit have a remoteturn-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.

The AVA- 1 204 and AVA-1404 do not have Volume Level controls,
Therefore,
all of your audlo system level controls are made at the
head unit or, in the case of the subwoofer output, at the amplifier
(or its remote control unit) dedicated to the subwoofer channel.
In the case of the amplified model AVA-1404, the amplifier in the
equalizer unit adds a very large power boost! So when you first turn
on the system, be sure your head unit volume control is set at the
minimum level. Then you can raise it slowly to see the effect the
new equalizer has on the overall system volume level.
