Analog
IN/OUT
and

This unit is
provided with both analog and digital inputs
and
outputs,
and
you can
use
both of
tilt'm at the
same
time. The
input
block in the
SYSTEM:
Setup

lets
you
determine
whether
to
usc the anall'g, the digital,
or
both the
analog
and
the digital INPUT

Analog
INPUT
priority
This unit is
pro\'ided with both
PHONE
and
XLR
type
analog
INPUT
and
OUTPUT jacks.
Although
the
sign,,1
is
always
output
from both the
PI
lONE and
XLR
jacks, the
PHONE
jacks
are
gin:-n priority
for
the input signa
I.
When the PHONE
and
XLR
INPUT jacks
are
used at the
same
time, th,'
XLR
signal
is
autl>matically cut.
Emphasis
Somc older CDs have
"emph"sized"
high frequency
sounds.
When
outputting
an analog signal
from an
"('mpha~izl'ti"
digital source,
it
is necessary
to
"de-emphasize"
th~
high frequenc),
sounds
and bring them back to their original levels.

Bypass
and
Mute
The
bypass
function
outputs
the
sound
of
the signal originally
input
into
the
effector
without
adding
any
dfl'cts. Pressing the
bypass
button
turns the
bypass
function
on
and
off.
"Mute" is also ,wajJable as a form
of
bypass. When the BYPASS
button
is set to mute, the
sound
of the originally signal is cut in
"ddition
to
th"
sound
of
th<l
eff<lcts.
Th"rcfor", no
sound
comes
from thl' unit. You can set BYPASS
button
to
operate
,1S either
"Mute"
or
"llypass" in the
SYSTEM:
Setup
menu.
'Q'--------------"\
Muting
the
sound
is
more
than
just
turning
the
volume
to
"0." It is
designed
to
prevent
sound
from
returning
to
the
mixer
when
the
unit
is
connected
in a
send-
return
loop
with
a mixer. Ideally.
when
this
unit
is
connected
to
a mixer.
the
sound
of
the
input
signal
is
should
not
be
output
from
this
unit,
only
the
sound
of
the
effects
should
be
output
(see
"Cutting
the
Direct
Sound
(Dry
On/Off)"
on
page
25). In
this
situation,
however,
using
bypass
only
cuts
the
sound
of
the
effects.
and
the
sound
input
into
the
effector
goes
back
to
the
mixer,
producing
a
double
signal. Using
mute
prevents
the
sound
input
into
the
effector
from
returning
to
the
mixer
and
insures
that
only
the
sound
generated
from
the
original
source
(guitar,
keyboard,
etc.)
reaches
the
mixer.
In
other
words,
it
is
the
same
as
bypass.
