FILTER TYPE selection switch NOTCH position (see below).
FILTER TYPE rotary switch
This selects the modulation source that will affect the filter cut-off.
There are 4 types of filter;
LOW PASS
LPF filter - signals above the cut-off frequency are attenuated 12dB/octave.
BAND PASS
BPF filter - signals above and below the cut-off frequency are attenuated 12dB/
octave.
HIGH PASS
HPF filter - signals below the cut-off frequency are attenuated 12dB/octave.
NOTCH
Notch filter - signals at the cut-off frequency are attenuated 12dB/octave.
Filtering External Sound Sources
External sound sources, such as vocals, guitars, mixer sends, samplers, etc. can be
sent through the filter for extra treatment. Note, mic's and guitars may need pre-amp'ing;
use if the signal is too quiet.
Simply plug the sound source into the rear panel EXT1 socket.
Turn the mixer control Noise/EXT1 to EXT1, and up to a suitable level.
You may wish to return the VCO1 and VCO2 mixer controls to their centre positions
so the VCOs cannot be heard.
Turn the VCA mode switch to ON. This will leave the VCA open so a constant signal
can be heard.
Finally, play around with the filter and modulation settings as neccessary.
The VCO signals can also be introduced, and use the various VCA modes and enve-
lopes if you wish to contour the sound level and add additional effects.
