Introduction
SY03 is a VC low pass filter and VCA in one module. The VCA is
hard-wired in series after the filter output.
The filter is a transistor ladder 'Moog' type filter. Resonance can be
set to feedback.
Controls In Detail
SIG1 LEVEL
Audio input signal attenuator for the signal coming into the SIG12
socket.
CV1 LEVEL
CV input signal attenuator for the signal coming into the CV1 socket.
CUT OFF
Alters the filter cut-off frequency.
RESONANCE
Alters the filter feedback level.
VCA LEVEL
VCA CV level attenuator for the signal coming into the VCA CV socket.
When no jack plug is in that socket, the control is used to attenuate a full
CV level (+12v).
Sockets In Detail
SIG1 IN
Signal input to the filter, level affected by SIG1 control.
SIG2 IN
Second input to the filter. There is no level control.
CV1
Cut Off CV input, level affected by CV1 LEVEL.
CV2
Second CV input. There is no level control.
VCA CV
VCA CV level input, level affected by VCA LEVEL control. When no plug is in this socket, the VCA receives a full
(+12V) CV level, which can then be attenuated by the VCA LEVEL control.
SIG OUT
Signal out from the VCA (i.e. filter).
