Mixer; Voltage Controlled Filter - Moog MEMORYMOOG 345 Owner's And Service Manual

7.0
MIXER
Four
level
controls for adjusting the
relative
volunnes of the
three oscillators
and
a
pink noise source
as
they
feed into
the
filter.
Note
that
beyond
a setting
of
4
or
5,
these controls
iy
cause the
signals to clip (distort).
This
gives a
little
more
punch
to a
sound where
desired.
It
also
turns the
triangle
waves
into sine
waves.
At
a
setting of
1
you
will
hear
some
intermodulation
distortion.
