Stereo Expander
The Stereo Expander works on the principle of mixing so called
“off center signals”. The process involves electronically deter-
mining which parts of the stereo canvas are left and right. These
L-R contents are then doubled and mixed in reverse phase to
the opposite channel. The effect becomes one of producing an
effect of an enlarged, grander stereo panorama.
Such stereo expansion can have an even more significant appli-
cation in either mixes—especially subgroup mixes—with chorus
or backups such as guitars, synths, and in widened overhead
miking.
Stereo Expander/Expander On
The Stereo Expander is toggled in and out of the chain by a hard
bypass relay control switch (an illuminated orange status LED
indicating that the expander is active).
Stereo Expander/Stereo Width
The Stereo Width control determines the amount of phase-
inverted signals added. As you might guess, in addition to its
widening the stereo image, the expander will also increase a
signal’s overall level. In such cases, you can correct levels with
the output control.
