Section 2— Control Panel Descriptions
(TOP/GAIN) is a two-purpose knob whose operation is dependent
on whether the BOX button or the MASK BUS or MASK STORE
button is pressed. If BOX is active, the (TOP/GAIN) knob controls
the top side of the box-style mask (see BOX button description). If
MASK BUS
is active, the (TOP/GAIN) knob controls the gain of the
Mask bus clipper.
(BOTTOM/CLIP) is a two-purpose knob whose operation is
dependent on whether the BOX button or the MASK BUS or MASK
STORE
button is pressed, just as with the (TOP/GAIN) knob. If BOX
is active, the (BOTTOM) knob controls the bottom of the box-style
mask (see BOX button description). If MASK BUS or MASK STORE
is active, this knob controls the Mask bus clipper.
The (LEFT) and (RIGHT) knobs control the left and right sides of
the box-style mask. They are inactive if BOX is not selected.
The MASK INVert button inverts the polarity of the signal used to
create the mask. A mask that normally allows a key inside of a
box, will allow a key outside the box when MASK INVert is on.
Mask Invert functions with all mask sources.
