To
obtain
less
bass
(retaining original
program material balance)
1.
Operate
the
BASS
COUPLING
control towards
"10" (wideband).
To make
"Air"
sound most
like
"Program"
1.
Operate
with the
BASS
COUPLING
close to
"10".
(Adjust the control to
make
the
BASS
and
COMPRESSION G/R
meters
track
as
closely as possible.)
2.
Operate
with
the
RELEASE TIME
at
"8"
in
LINear mode.
(This
may
cause
gain-riding to be too slow.)
3.
Use
approximately
lOdB
of gain
reduction
("0" on the
TOTAL MASTER G/R
meter) by adjusting the
INPUT
ATTENUATOR
as
necessary.
4.
Minimize
the
amount of clipping and
HF
limiting
by operating
HF
LIMITING
at
"10"
(full
hard),
and backing off the
CLIPPING
as far as
required to avoid
audible distortion on difficult
material
like
male
voice or piano.
To
obtain "open"
sound with no audible
compression
1.
Operate
the
RELEASE
TIME
control
at "8".
2.
Do
not
pre-compress program material
in
production.
To
obtain a "heavily-processed"
sound
1.
Operate
the
RELEASE
TIME
control
at
"0"
and the
BASS
COUPLING
control
at
"0". (You
may
have
to
back
off the
CLIPPING
and
HF
LIMITING
controls
to avoid objectionable
distortion.
Operator gain riding will also
become
more
critical.)
To
avoid "noise
pump-up"
1.
Operate with lOdB of gain reduction
("0"
on the
meter) with normal
levels
out
of
the console
or
switcher.
2.
Adjust the
GATE THRESHOLD
more
clockwise.
3.
Use
slower
RELEASE
TIME.
To
achieve
more
subtle gain riding
in
wide-dynamic range material
1.
Critically adjust the
GATE THRESHOLD
control so that
medium-
to
low-
level
passages
cause the
GATE
lamp
to flash
on
and
off,
thus slowing
down
the
release
time
as
the
program
gets softer.
To
avoid excessive sibilance (particularly
on
women's
voices)
1.
Use
an
Orban
Dynamic
Sibilance
Controller on
speech
inputs
only
.
(While
OPTIMOD-TV
will
not
distort sibilance,
its
excellent high frequency
power
handling
capability will result
in
its
passing
high-energy sibilance present at
its
input instead of limiting
it.)
