Important Safety Instructions
Terminals marked with
this symbol carry electrical current of sufficient magnitude to constitute
risk of electric shock. Use only high-quality professional speaker cables with
¼” TS or twist-locking plugs pre-installed. All other installation or
modification should be performed only by qualified personnel.
This symbol, wherever it
appears, alerts you to the presence of uninsulated dangerous voltage inside
the enclosure – voltage that may be sufficient to constitute a risk of shock.
This symbol, wherever it
appears, alerts you to important operating and maintenance instructions in the
accompanying literature. Please read the manual.
Caution
To reduce the risk of electric shock, do not remove the top cover (or the rear
section). No user serviceable parts inside. Refer servicing to qualified
personnel.

Getting Started
CONNECTION
To connect the System 15 to your system, please consult the connection
guides in specific patches.
HARDWARE SETUP
Make all the connections in your system. Keep the System 15 power turned off
when making any connections. Ensure your sound system is turned down. Turn on
the System 15 before turning on any power amplifiers and turn it off last.
This will help prevent any turn on or turn off “pops or thumps” in your
speakers.
WARM UP TIME
We recommend leaving 30 minutes or more time for the System 15 to warm up
before recording or live performance. (Longer if it has been brought in from
the cold.) This will allow the precision circuits time to reach their normal
operating temperature and tuned performance.

This patch allows a delayed vibrato effect to fade in when a note is held. The external keyboard controls the pitch and triggering of notes via the CM1A MIDI Interface. As this can be switched between v-trigger and s-trigger then s trigger should be selected and the 961 Interface need not be used. Pitch CV is fed to one of the 921As, which daisy chain to the 921B VCOs. The selected waveform from each oscillator is fed to the CP3A-M mixer; which then feeds the 904A LPF. S-triggers are fed to a multiple, and then to the 911s’ s-trigger inputs The output of the 904A LPF is fed to one of the 902 VCAs, which feeds out to your mixer, amplifier or DAW. This VCA is controlled by the first 911 EG. The second 911 EG controls the second 902 VCA. The second 902 VCA signal input is fed from the 921 LFO. Its output is fed to one of the CP35 multiples, whose outputs feed the DC Modulation inputs of the 921B VCOs The second 911 should have a long attack time and full sustain. So long as the first 911 has a long sustain time, when a note is held a vibrato effect will fade in slowly. When notes are played legato there is little or no vibrato
Space Rock
This patch creates two of the classic ‘space rock’ sounds, and allows them to be mixed together.

Control settings are very important for this patch.
Regeneration on the 904A must be set to 9 or 10 to force the filter to self
oscillate
The 921A should have Octave selected and the frequency control set to -6
The 921Bs should be set to ‘Lo’ – these oscillators provide the sweep to the
filters
The 921 should be set to ‘Sub’ – this is the main modulation for the self
oscillating filter, and manual alteration of the Frequency control helps to
produce the classic sound.
The pink noise feeding the 904B produces a swept wind effect, that can be
altered with the Fixed Control Voltage Altering the Fixed Control Voltage of
the 904A also produces interesting effects
The CP3A-M balances the two signals, as an alternative feed the outputs of the
two filters direct to two mixer or amplifier channels. Both sounds benefit
from a lot of echo!
Expressive Lead #2
A simple, two oscillator lead sound with a hard front end and timbral development which is also suitable for melodic sequencing

The detuned 921B VCOs give a fat sound, whose timbre changes constantly at the
speed of the 921 sine wave – the 921 should be in Sub mode, speed can be
adjusted to suit.
The sound comes from the 904A LPF, whose Fixed Control Voltage and
Regeneration can be set to whatever suits your aim, plus modulation from the
second 911 EG.
EG settings can be adjusted to suit for the main part of the sound, although
medium to high levels on T2 (decay), T3 (release) and E sus(tain) are
recommended.
The second EG should have a medium length T1 (attack), medium T2 (decay) and
minimal T3 (release) and E sus(tain)

This sound uses two 921B VCOs, with different waveforms, and sounds best if
one is slightly detuned. They both feed the 904A LPF, and their relative
levels can be adjusted with the CP3A-M mixer as required. The 904A’s output is
fed to a 902 VCA, whose amplitude is controlled by the 1st 911 EG
To obtain the percussive edge the 911’s settings should be T1 (attack) 2ms, T2
(decay) 200ms, T3 (release) 200ms, E sus(tain) 4 seconds
The 904A is modulated by a slow sine wave from the 921 LFO and by the 2nd 911
EG, which should have settings around T1 (attack) 1 second, T2 (decay)
50ms,T3 (release) 4 seconds, E sus(tain) 9
