Overdrive
This switch enables/disables the Overdrive circuit of the EVOC 20 FB.
Note: To actually hear the Overdrive effect, you may need to boost the level of one or
both filter banks.
Level
The Level slider controls the level of the EVOC 20 FB’s output signal.
Stereo Mode
This pull-down menu determines the input/output mode of the EVOC 20 FB. Choices
are: m/s—mono input to stereo output and s/s—stereo input to stereo output.
• The Stereo Mode should be set to m/s if the signal going into the EVOC 20 FB is
monophonic, for example a mono audio track.
• Stereo/stereo (s/s) is the preferred setting for stereo input signals. In this case, the
stereo signal is processed by separate filter banks for the left and right channels.
When using the m/s Mode on stereo input signals, the stereo signal is first summed
to mono before it is passed on to the filter banks.
Stereo Width
Stereo Width distributes the output signals of the filter bands in the stereo field.
• In the left position, the output of all bands are centered.
• In the center position, the output of all bands ascends from left to right.
• In the right position, the bands are output evenly on the left and the right channel.
The stereo/stereo mode (s/s) uses one A/B filter bank per channel. The positioning of
the frequency bands correspond to that described above, but the bands of each filter
bank ascend in opposing directions, from left to right.
