Names of Things and What They Do
(MUTE, ANTI-FEEDBACK)
Connecting a foot switch pedal (optional BOSS FS-5L, FS-5U,
or FS-6) using a connection cable (the optional PCS-31) makes
it possible to use a latch-type foot switch (the FS-5L or FS-6)
to switch muting on and off, or to use a momentary-type foot
switch (the FS-5U or FS-6) to control the anti-feedback
feature.
* For information on the settings for the FS-6, refer to the
owner's manual for the FS-6.
fig.050
When a 1/4" phone (mono) plug is used to connect only one
foot switch, only the Mute on/off function is enabled. In such
cases, you should use a latch-type foot switch pedal (such as
the BOSS FS-5L)
* The MUTE button should be set to off when a foot switch is
connected for muting.
You cannot switch the muting off by pressing the foot switch
when the MUTE button is on (when the MUTE indicator is
lit).
* When using an FS-5U (momentary type) to switch muting on
and off, the muting is switched on only while the switch is held
down.
For anti-feedback, a foot switch will function as follows:
• When the FREQUENCY knob is positioned in the range
from L to H, the switch turns the anti-feedback function
on and off.
• When the FREQUENCY knob is positioned at AUTO, the
switch functions as the START switch for the automatic
detection. Holding the foot switch down for one second
or longer returns the automatic detection function to
standby mode.
(CHORUS, DELAY/REVERB)
Using a special connection cable (the optional PCS-31) to
connect two foot switches (the optional BOSS FS-5U), you
can use one FS-5U to switch the chorus on and off, and use
the other FS-5U to switch the delay or reverb on and off.
fig.060
When a 1/4" phone (mono) plug is used to connect only one
foot switch, only the chorus on/off function is enabled.
* The chorus on/off function works on both channels.
* You cannot switch the chorus on and off by pressing the foot
switch when the CHORUS button is off.
