Analog IN/OUT and digitaliN/OUT
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 menu lets you determine whether to
usc the anall'g, the digital, or both the analog and the digital INPUT /OUTPUT jacks.
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. The (lnputl block in the SYSTEM: Setup menu lets

Even though you can decrease levels in the mixer block. the most important factor
in preserving sound quality is the input level. The following is a general guide line
for adjusting the input level, but your eyes and ears are ultimately the most useful
tools in determining and maintaining the appropriate input level.

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.

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.
