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-
amping use if the signal is too quiet.
Simply plug the sound source into the front panel EXT4 socket.
Turn the mixer control Noise/EXT4 to EXT4, 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 necessary.
The VCO signals can also be introduced, and use the various VCA modes and
envelopes if you wish to contour the sound level and add additional effects.
Note; The rear panel input sockets are wired direct to the mixer input.
