INPUT, OUTPUT. These
jacks
are
for
a
line-level
input
and
ouput
and are
the
stan-
dard
2-circuit
("mono")
1/4"
phone
type, where
the tip
carries
the
signal
and the
sleeve
carries the ground.

KEY
IN. Use this
jack
if you
want
to
control the
463X
gating
action from
an
external
source,
allowing
you
to
alter
the dynamics
of
one
signal
with
another.
Same
plug type
as
above.
Key
In will
be discussed in
detail
in
the
Applications
Note.

Hi-2
trim. This
screwdriver
control
sets the
gain
of the
preamp
for
the
Hi-Z
input
only
(see
front panel).
The gain
is set at the
factory at +20
dB
(all
the
way right,
or
clockwise)
and
shouldn't
be
changed
unless
your
instrument's
output is
very hot.
All
the
way
left
(ccw)
is unity
(0
dB)
gain.

STEREO
STRAPPING
jack
and button.
Connect
this jack
to the same
jack on
another
463X
and you have
a
true
rms-detecting
stereo
noise gate.
Connect
it
to
a
1
63X
and
you
have the same
thing
—
a
stereo
pair
of
noise
gates
—
provided
this
first
unit
remains
the Master
.
But
if
you connect
it
to
a 163X and
press
the
button
in,
to Slave,
this
unit
becomes a
163X
and you
have
a
true stereo
pair of
163X
compressor
/limiters.
Neat, huh?
The
jack is a
1/4"
3-circuit ("stereo")
phone type
(tip/ring/sleeve);
use 3-circuit
plugs
and cables only, for
anything
else
won't
work.
Of
course,
be
sure to disconnect
everything
for
independent
operation.
Note
that
you must
leave
the
Master/Slave
button
out,
at
Master,
for
normal
463X
(non-stereo)
operation
as
well
as
for
stereo
operation
as
a
Master.
Pushing
it
in,
to Slave
(the
front-panel
LED
will
light),
deactivates
the
controls
and
forces the
unit
to obey
the
Master's
settings
when
a
second
463X
or a
163X is
properly
con-
nected
and
switched. (If
you push
the
button
in
when
no
Master
is
connected,
it's
a
bypass
switch
for
the gate
only; the
preamp
still worksT)
5 VOLTAGE
SWITCH.
This
must
be
properly
set
for
your
ac
voltage;
be
sure
to
check
before
plugging
in and
powering
up. For nominal
220-V
operation
an
adaptor
plug
on
the
ac cord
will
be required.
