EE PRACTICAL APPLICATIONS OF THE
PARAMETRIC EQUALIZER
The C-80's Parametric Equalizer offers extensive control over
tone quality. It can be used to adjust for room acoustics, speaker
placement, or personal preferences. A LOW band and a HIGH
band are provided, each with its own adjustable center
frequency, bandwidth, and level (boost/cut).

1) Compensating for Room Acoustics
i à spectrum analyzer or sound leve! meter is available, you will
be able to accurately flatten your listening room's acoustic.
response using the Parametric Equalizer controls. For example, if
a response dip in the high frequency range (often due to sound
absorption by carpet, drapes, stuffed furniture or even people) is :
detected, use the HIGH Parametric Equalizer band to create a
corresponding response peak of equal but opposite BANDWIDTH
and LEVEL.

T appropriate test instruments are not available, however, rough.
compensation can be done by ear. For instance, if the bass -
range sounds too "boomy", indicating a low frequency peak, try
setting the LOW range BANDWIDTH to WIDE and the LEVEL
control to maximum cut, then sweep the FREQUENCY control
through the bass range until you hear the boominess disappear.
then, finally, readjust the BANDWIDTH and LEVEL controis for
the most natural overall sound.

2) Eliminating Noise or Hum
it there is an annoying hum or noise during operation of your
system, it can be effectively eliminated using the Parametric
Equalizer. In the case of a high-frequency whine, for example, try
setting the HIGH range BANDWIDTH to the maximum NARROW
position and the LEVEL control to maximum
cut, then sweep the
FREQUENCY control through the high frequency range until you
hear the interfering frequency noise disappear. Then, fínally,
readjust the BANDWIDTH and LEVEL controls for the most
natural overall sound.
