Specifications
Front
Out
The Front Out mode processes the stereo input and
outputs it
to
a two-channel front speaker system. The
effect expands the source sound and makes it seem more
three-dimensional and spacious than conventional stereo
sound

ms
This control is used to adjust delay time: however, the
time difference set here has the sonic effect of altering
the character of the surround processed sound.
Sweep
Flanger
This is a special flanging effect that provides three
different types of modulation waveforms, selectable from
five different modes. With the three-phase LFO
operation and the automatic gradual application of the
effect, Sweep Flanger creates an effect in which the
resonant frequency is continuously swept up or down.

Rear
Out
The Rear Out mode applies the surround effects to a
stereo source for use with
a
pair of rear speakers in a
four-speaker system. In this setup, the source signal is
split, one set of stereo signals going to the
9120
for
processing (and then to the rear channels), and the other
set
going unprocessed
to
a separate amp/speaker system
for
the front channels.

LFO:
Stereo three-phase flanger
In another setup example similar to the one above, two
9120s could
be
used to create the optimum four-channel
surround system. One
9120
could be used in Front Out
mode to drive a pair of front speakers, while the other is
set
to
Rear
Out mode and drives a pair of rear speakers.
All modes feature three-phase
LFO
operation, not
M
only
the
Tri
LFO
mode.
