PQM OPERATION

The PQM is a one band parametric equalizer Adjustments are made using
the three circuit board mounted potentiometers These controls are
simple to operate and provide a wide range of adjustment
F F R R E E Q Q U U E E N N C C Y Y C C O O N N T T R R O O L L is used to select
the center frequency for equalization
A clockwise rotation increases frequency
while a counterclockwise rotation decreases frequency
F F R R E E Q Q U U E E N N C C Y Y M M O O D D U U L L E E : : The supplied frequency
modules divide the audible frequency range into
three bands The range of the modules are: Hz
to Hz Hz to kHz and kHz to
Simply install one of the modules and its frequencies are selectable
via the

" " Q Q " " A A D D J J U U S S T T M M E E N N T T : : "Q" is the property of
an equalizer that determines the range of
frequencies affected on either side of the cen
ter frequency "Q" is equal to the center frequency divided by the
bandwidth As "Q" goes up bandwidth decreases The PQM's "Q"
adjustment ranges from a narrow bandwidth of
bandwidth of A clockwise rotation increases "Q" while a coun
terclockwise rotation decreases "Q"
B B O O O O S S T T / / C C U U T T : : This control is used to boost
or cut the level of the center frequency
Its adjustment ranges from d d B B o o f f c c u u t t at
full counterclockwise rotation to d d B B o o f f
b b o o o o s s t t at full clockwise rotation Flat response ( dB – no cut or
boost) occurs at mid rotation when the slot on the control is in
the horizontal position
