A.
THRESHOLD
control:
The
Threshold
control
sets
the
level
at
Which
the
gate
will
open and
allow
the
signal
iat
the in-
put
to pass
through
to the
output.
The
363X
has
an
80dB
threshold
range
which
will
allow
it
to
be used
with
a
variety
of
low
level
and
line
de-
vices.
Turn
the
THRESHOLD
control
com-
pletely
clockwise.
Set the
HOLD
control
to the
OFF
position
and
set the
RELEASE
control
around
lOOOdB/S.
Apply
the signal
to be
gated
to
the
input
of
the 363X
and
adjust
the
1
THRESHOLD
control
counter-clockwise
until
the
signal
can
be heard
at the
output.
The
THRESHOLD
control
should
be set
so the
gate
opens
every
time the
signal
is
applied.
If the
dy-
namics
of
the instrument
being
gated
changes
dramatically
in
the
context of
the
perfonnance,
it may
be
necessary
to
re-adjust
the
THRESH-
OLD
to allow
the softer
signals
to
open
the
gate.
B.
OPEN
LED
;
The green
LED
labelled
"OPEN"
illuminates
when
the signal has
crossed
over
the
set
thresh-
old
level
and quickly
extinguishes
when
the
sig-
nal
falls
under
the
threshold.
This LED
can
also
serve
as a signal
present
indicator
when
trouble-shooting
through
your
system.
C.
HOLD
control
I
The
Hold
control
is
used
to
reduce
false
trigger-
ing
and
to allow
for
a certain
amount
of
decay
time
inherent
to
some
types
of
musical
instru-
ments.
The
hold
circuit
begins
its
timing
proc-
ess
once
the
signal
falls
under
the
threshold
.
The
363X
provides
up
to a
maximum
of
3
sec-
onds
of hold
time.
An
example
of
when
the
hold
function
would
be
utilized
would
be
to
al-
low
a
piano
of
guitar
to fade
naturally
without
truncating
the
signal.
Or
another
use
would
be
to
capture
the
reverb
as it
is
trailing
off
after
the
initial
snare
drum
hit. In
order
to
capture
the
entire
envelope
naturally,
it
will
be
necessary
to
use
the
Release
function
in
conjunction
with
the
Hold
function.
However,
using
a
long
hold
time
with
a
short
release
time
can
create
some
interesting
special
effects.
D.
Hold
LED
When
the
Hold
function
is
used,
the
yellow
LED
labelled
"HOLD"
illuminates
when
the
signal
falls
below
the
threshold
and
remains
il-
luminated
until
the
hold
circuitry
has
com-
pletely
timed
out.
