HOOKUPS
Inputs
and
Outputs
The
line-level
inputs
and
outputs
are
single-ended
(unbalanced)
and
should
be
con
nected
to
other
such
equipment
with
single-conductor
shielded
cable,
as
shown
here.

This
will
work
fine for
balanced
inputs,
too,
but
if
the
463X
input
is
connected
to
source
equipment
with balanced
outputs,
the
next
hookup
should
be
used.
Most
balanced
sources
will
work
without
the
dotted
connection
between
the
ring
(-)
output
and
the
sleeve
(the
ground
--
this
is true for
"active-balanced"
and
"ground-referenced"
outputs).
This
float-
ing
condition
unbalances
a
balanced
source,
which
is
usually
okay.
However,
some
sources
require
the
dotted
connection,
e.g.,
"transformer-isolated"
balanced
outputs.
We
recommend
making
the
connection
only
if
necessary
for
your
installation,
because
some
active
balanced
and
ground-referenced
outputs
may
be damaged
by
doing
so.
Consult
the
owner's
manual.

To

provided
by
the
balanced

the

may
be used

The
connection
between
the
shield
and
the
sleeve
at
the
463X
end
of
the
cable
should
be
made
only
if
hum

in

installation.
The
Key
input
jack
provides
a
direct
connection
to
the
463X's
"brains"
—
its
level-sensing
circuitry,
or
rms
detector
—
without
disturbing
the
normal
audio
path.
This
feature
lets
you
control
the
gating
from
an
external
signal
source,
or
lets
you
add
processing
(e.g.,
equalization)
to
the
control
path
only.
This
jack
overrides
the
detector's
normal
connection
to
the
main
input
signal
(see
the
block
diagram,
p.
9).
Plugs
and
cabling
are the
same
as
in
the
two
illustrations
above.
The
Hi-Z
(instrument)
input
is
single-ended
(unbalanced)
also
and
should
be
connected
to
instrument
outputs
with
single-conductor
shielded
cable
as
shown
at
the
top
of
this
page
for
line-level
jacks.
