Power ON/OFF Switch
Press to turn power ON, press again to turn power OFF.
When the power is turned ON, the last program and
parameter selected will be automatically recalled.
Input Level Controls
These concentric controls vary the input level of the
analog inputs from approximately -90 dB to +l0 dB when
the rear-panel input level switch is set to +4 dB, and
between approximately -110 dB and -14 dB when the
input level switch is set to -20 dB. The inner control
adjusts the left channel and the outer control adjusts the
right channel.
PARAM Key
Accesses the main effect parameters for each program.
Each time the PARAM key is pressed the next parameter
in the selected program's "parameter set" is called. It is
also possible to scroll backward through the parameter set
by using the SCROLL BACK key (7). Once the desired
parameter has been selected its value or setting can be
changed using the parameter
PARAM key is also used for cursor control (forward
cursor movement) in some utility functions.

LEVEL Key
Accesses the output level and balance parameters for
each program. Once the LEVEL key has been pressed,
both the LEVEL key and SCROLL BACK (7) key can be
used to select parameters. Once the desired parameter has

SCROLL BACK Key
When any set of parameters is selected – PARAM,
LEVEL, EQ, or INT PARAM – the SCROLL BACK
key can be used to scroll backward through the available
parameters while the PARAM (3), LEVEL (4), EQ (5) or
INT PARAMETER (6) key scrolls forward, according to
the parameter set selected. The preceding parameter in
the current set is selected each time the SCROLL BACK
key is pressed. The SCROLL BACK key is also used for
cursor control (backward cursor movement) in some
utility functions.
EXT CTRL ASSIGN Key
This key makes it possible to assign any parameters
(PARAM, LEVEL, EQ or INT PARAM) to external
controllers connected to the front-panel EXT CTRL/
FOOT VOL 1 and 2 jacks (21). These controllers can
then be used to control the assigned parameter in real
time. Yamaha FC7 Foot Controllers are recommended.
