Digital Effects Section
0PROGRAM dial
Selects the type of effect to be used. You can select from
16 different effect types, as follows.
APARAMETER knob
Adjusts the parameter (depth, speed, etc.) associated
with the selected effect type.
The mixer saves the last value used with each effect
type. When you change to a different effect type, the
mixer automatically restores the value that was previ-
ously used with that type (regardless of the current
position of the PARAMETER knob). But note that all
values return to their defaults at power-off.
BON switch
Switches use of the internal effector on or off. The inter-
nal effect is applied only if this switch is on. Note that
the lamp above the switch lights up orange to indicate
that the switch is on. As an alternative to the ON switch,
you can use a separately sold FC5 foot switch to toggle
the effector on and off.
The internal effector is automatically turned on when-
ever you switch on the mixer’s power.
CEFFECT OUT jack
This unbalanced phone output jack outputs the signal
from the EFFECT bus. You can use this jack to output
the signal to an external effector. You can then return the
signal by connecting the external effector to any of the
LINE jacks on channel pairs 5/6 to 11/12.
If you are returning a signal from an external effector
into a LINE jack on any channel pair 5/6 to 11/12,
please be sure to turn the EFFECT knob for that chan-
nel pair to “0”.
DFOOT SW jack
This phone input jack can connect to the (separately
sold) YAMAHA FC5 foot switch. With the foot switch
connected, you can use your foot to toggle the internal
effector ON and OFF.
