9.2. Change Safe Function Setting
The Change Safe function is a function to prevent the following parameters from being recalled when the
preset memory number is changed.
• Fader: Gain, channel ON/OFF, grouping number, group trim gain
• Matrix crosspoint: Gain, crosspoint ON/OFF
Assign the channel the fader belongs to and the matrix crosspoint to any one of 4 groups (a) to (d).
Then, the parameters of channel fader and matrix crosspoint assigned to the Change Safe group cannot be
recalled from the preset memory.
The Change Safe groups (a to d) are displayed in the Memory view, if set. (Refer to
p. 31 .)
Notes
• The Change Safe groups (see
p. 128 and p. 129 ) assigned to channels and matrix crosspoints are common
to all preset memories.
As long as the Change Safe group is set to the currently selected preset memory (see the next page), the
above-mentioned parameters of the channel (fader) and matrix crosspoints included in the group can neither
be stored nor discarded even if they are changed.
• If you set a preset memory where such 2 channels are grouped in the same grouping number as one
assigned to the Change Safe group and the other not, both channels' faders may indicate different values.
(See below.)
• When changing the fader's grouping number by external control protocol, also note the relation with the
Change Safe group setting to avoid the difference in fader values as explained above.

Recalls Preset memory 2.
Moving one of the faders makes both fader values
equal owing to the grouping function.
The fader value is maintained
by the Change Safe function.
The fader value and grouping
number are switched to those
saved in Preset memory 2.
