Button Functions:
Power:
Turn ON: Press I/O button (red) for 1 second
Turn OFF: Hold I/O button down for 3-5 seconds.
Battery status: Press I/O button briefly whilst powered on (light ring shows power level 1 to 8).
Autotune:
Press TUNE briefly to start a rapid automatic tuning of both VCO's.
Press and hold for >1 seconds to initiate 'fine' auto-tuning (takes longer).
Press and hold for >10 seconds to initiate factory-reset tuning which retunes to pre-set values then tunes
again from there (takes longer).
To cancel before the end of a tuning sequence, press TUNE button again.
Volume:
32 steps, increase and decrease using white buttons. Light ring shows volume level during adjustment.
Jack sockets:
Headphone:
Plugging in headphones switches off internal speaker. Adjust volume with vol buttons.
Aux IN:
Plugging in external signal switches off both VCO's and sets VCA to maximum. This signal passes through
the filters of the instrument so some signals may appear distorted or altered when played through the line-
out. This feature is not suited to playing complete musical tracks through the instrument.
CV/TRIG IN:
Disables keyboard when CV jack plugged in.
CV 0-5v range, will respond to 9.9v.
Trig: 2-10v
When in use: Octave UP pad toggles quantizer ON/OFF, Octave DOWN changes start octave and start
voltage (0v or 1v) - 4 settings. PLEASE cycle through the options to achieve a reliable trigger.
Line output:
Main output, unaffected by volume control. This is a classic line-out and does NOT disable the internal
speaker. Turn volume down to zero to use without internal speaker.
External DC Jack:
2.1mm jack. Centre positive. Diode protected against reverse polarity,
9-15v @ 500ma.
Knobs:
All ten knobs are self explanatory and their function is listed on the diagram overleaf. The only exception is
knob 2 which it should be noted is a standard mix control for VCO1/2 whereby at the full left (anticlockwise)
extreme you will hear 100% VCO1 and 0% VCO2. At the mid-way (12:00) point you will hear a 50/50 mix of
VCO1 and VCO2. At full right (clockwise) you will hear 100% VCO2 and 0% VCO1. This allows the knob to
effectively act as a switch to use the instrument as two separate single oscillator synths and set VCO1 and 2
up with different sounds, eg: for a performance situation.
Please see overleaf for a diagram of the touch pads and knobs on the S2 and their functions:
PLEASE: Re-read these instructions carefully if you have any issues using your S2. This is a complex instrument with a very
compact user-interface which may be different to other synths you have used before. If you hit an apparent problem and need
some assistance, please contact Dubreq directly at: support@dubreq.com
