Sockets
IN1, IN2
These are both audio inputs to the filters. Input 1 goes via the Input level pot.
HPF CV1, CV2
These are external CV inputs to control the HPF cut-off frequency. Input 1 goes via the HPF CV pot.
LPF CV1, CV2
These are external CV inputs to control the LPF cut-off frequency. Input 1 goes via the LPF CV pot.
VCA CV1, CV2
These are external CV inputs to control the VCA level.
Audio Out
This is the audio output from the SY02.
Calibration
There are 2 trimmer pots on the main board marked HPF Q and LPF Q. These are used to adjust the intensity of the
resonance feed back. With these trimmers set at maximum (fully anti-clockwise), it is possible to really self-oscillate the
filters (when the resonance pot on the front panel is also at a high/maximum setting. Note however that if the resonance
self-oscillates at too higer level, distortion may result (although this is not always a bad thing. Set the Q trimmers to a
setting that gives you the amount of resonance you want balanced with an acceptable level of distortion. This is done
before SY02s are sent out.
