OPERATION
The V-9975 is used to boost or attenuate specific
frequencies to improve voice intelligibility or
attenuate frequencies to help reduce feedback. The
unit can also be used to modify the frequency
response of speakers.
A "POWER" indicating LED, 7 slide controls (1 for
each of the bands), and an "EQ" bypass switch are
located on the front of the unit. The frequencies
boost/cut (1 to 12 dB), are modified with each filter's
slide control. The manual "EQ" bypass switch allows
comparison of before equalization, and after effect, in
the area being equalized. All frequency adjustments
are bypassed when the "EQ IN/OUT" switch is in the
"OUT" position.
INSTALLATION
Connections are accomplished utilizing (3) phono
jacks (2 input, 1 output) and/or (9) screw terminals.
Only qualified service personnel should install the
V-9975. See Figures 1 and 2 for actual connections.
After all connections are made and slide controls
adjusted to the desired positions, close security cover
and tighten locking screws. All connections should
be made and double checked before DC power is
supplied to the unit.
