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.
