OPERATING INSTRUCTIONS
3.1
SETUP PROCEDURE
This
portion
of the
manual gives
a
step-by-step procedure
for
setting
of all
controls on
the
Model
562.
1.
Set the
Feedback Suppressor's Bypass
to "In"
position.
2.
Set the
Setup/Operate switch
to
"Setup" position.
3.
Set the Gain control
to
mid position.
4.
Set the Depth control fully
counterclockwise.
5.
Set the
Frequency control fully counterclockwise.
6.
Set the
Frequency Range switches
to "XI"
position.
7.
Slowly increase
the
microphone
level (using the mixer's
level control) until the first feedback frequency
becomes detectable
and has
stabilized.
8.
Turn
the
first Depth control fully clockwise (maximum
depth) and tune the associated Frequency knob until the
feedback disappears.
If
the
feedback cannot
be tuned
out,
set the Range switch
to "X10"
and turn the
Frequency knob until
the
feedback disappears.
With maximum Depth
the
feedback frequency may
be at the
skirt
of the filter; for
a
more accurate tuning, reduce
the
Depth setting and retune
the
Frequency,
if
necessary,
to
eliminate
the feedback.
9.
Increase the microphone level
so the
next feedback
frequency will appear,
and repeat the
procedure
of
step
8.
Similarly, continue
to
increase the
microphone level
and
eliminate
the third,
fourth
and fifth feedback frequencies.
10.
The Suppressor In/Out switch can
be
set to "Out" to
assess the effect
of the
Feedback Suppression settings.
CAUTION:
After setup,
be sure to
de-activate
the
clipper by returning
the
Setup/Operate switch
to the
Operate position.
Otherwise severe signal distortion
will result.
11.
Use the Endcut filters to restrict the
bandwidth
of the
processed program material
as
desired.
