Stereo Expander
The STEREO EXPANDER function is meant to create the
impression of a wider stereo image. The space image
is improved by doubling signals originally placed left
or right in the stereo image, inverting their phase and
summing them with the opposite channel. This results
in a better perception of the original signals while
the stereo image seems to reach out of the speakers’
plane. Mono signals placed in the center of the stereo
image are diminished during the process. We recommend settings
between 6 and 14. For high settings, and depending on the nature
of the source signal, you should always check the mono compat-
ibility of the signal with the help of a goniometer.
Output
The OUTPUT knob reduces or increases the output level.
The control ranges from -20 dB to +6 dB. The 0 dB mark
is set at the center position. Generally speaking, you will
need to reduce the level, considering that the Vitalizer
processing tends to increase it. If you set the input level
to 0 dB with the DRIVE control – which ought to be a good
starting point for filtering – there will undoubtedly be an
increase in level after the processing occurs.
IMPORTANT:
Use the OUTPUT control to exploit the dynamic range
available, but try to avoid distortion. The OVL (Overload) LED next
to the OUTPUT control can be very useful at that. The OVL LED
indicates overloading is occurring at the plug-in’s output, which
can result in distortion. You should always avoid the OVL LED from
turning on. If it does, use the OUTPUT control to reduce the output
level until it turns off.
