The
Ratio
knob
controls
how much
the
signal
will
be compressed once
it's
well
above
the threshold,
in
the
straight-line
section of
the
OverEasy
curve.
The
ratio
is
the
change
in
input level divided
by
the
change
in
output
level, e.g.,
a
4:1
setting
means
that
for
a
4-dB
increase
in
input level
the output
will
increase
by
only
1
dB.
At
Infinity:!,
the output
will
remain
at
a constant
level
irrespective of input
dyna-
mics
(as
long
as
the
input
is
above
threshold)
—
in
other words,
full
limiting.
5
GAIN
REDUCTION
LEDs. These show
how much
the
signal
is
being attenuated
by
the Gate, the Compressor,
or both.
6
PEAKSTOP
LEVEL
knob. This
sets
the
maximum
peak-output
level.
The
control
is
calibrated to the
rms
value of
a
sine
wave
just
being
clipp^. The
LED
lights
when-
ever
this
clipping
—
soft at
the
start,
becoming
hard as necessary
for
absolute
protection
—
occurs.
See
the note
on page
9.
This
is
the
last
circuit
the
signal
goes
through, so
it
always
controls the
maxi-
mum
output regardless of
any
other control
—
including
Output
Gain.
7
SIDECHAIN
MONITOR
switch
and
LED.
Pushing
this
in
connects
the Sidechain
input directly to the
Audio
Out,
for
monitoring
the sidechain
signal
during setup.
Be
careful not to
push
this
button inadvertently
—
It
affects
what
you
(and
every-
body
else)
will
hear, or
what's going
to
a console/mixer
or
tape
recorder.
Note
that
PeakStop
is
in
the sidechain
signal
path
when
Sidechain Monitor
is
selected.
8
OUTPUT
GAIN.
This
knob
controls
the
overall gain of
the
166,
from
-20 to
+20
dB.
It is
independent
of
all
other controls although, as
mentioned,
it
does
come
before the
^akStop
circuit.
9
BYPASS
switch and
LED.
Pushing
this
in
provides
a hardwire bypass
for
the
166,
connecting
input
to output
(fully
balanced
if
so wired)
even
in
the
absence
of
ac
power.
10
STEREO COUPLE
switch
and
LED.
Pushing
this
in
turns the
166
from
a dual-mono
unit
with
two
identical,
independent
sets of controls into
a
stereo
unit.
Except
for
Sidechain
Monitor and
Bypass,
Channel
2's ccxitrols
are overriden by
Channel
I's in
the Stereo
Couple
mode. Note
that
the detection
circuitry senses
the true
rms
levels of
the
combined
signal,
so
it is
unaffected by phase
shifts
(or
other discre-
pancies)
between
the channels.
Among
other
benefits,
this
enables stereo
compres-
sion
without
loss
of
imaging
stability.

1
VOLTAGE
SWITCH.
This
must be
properly
set for
your
AC
voltage,
be
sure
to
check
before plugging
in
and powering
up.
For
220V
operation
you
will
need
a suitable
adaptor
plug.
