SAFETY INSTRUCTIONS
Before using Quadrantid Swarm, please follow the instructions for use of the instrument as this will warrant proper operation
of the instrument. Due to the fact that these instructions touch on product liability, we recommend you reading them care-
fully. Any claim for defect will be rejected if one or more of the topics have not been observed. Ignoring the instructions can
eventually void warranty.
• RISK OF ELECTRIC SHOCK! DO NOT OPEN OR MODIFY Quadrantid Swarm.
• REFER SERVICING TO QUALIFIED SERVICE PERSONNEL ONLY.
• TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-
SERVICEABLE PARTS INSIDE.
• e instrument may only be operated at the voltage noted on the power input on the rear panel. Before plugging in Qua-
drantid Swarm, always check for the correct voltage. Before using Quadrantid Swarm in a foreign country,check whether the
mains voltage is compatible with the unit.
• When Quadrantid Swarm is not in use, disconnect the power supply from the power outlet. is will save energy (and keep
your electric bill within reason).
• Never attempt to repair Quadrantid Swarm on your own. Never open the casing. For technical support, please get in touch
with Eowave.
• e instrument is not to be operated outdoors (never ever!) but in dry, closed rooms only. Never use the instrument in a
moist or wet environment or near ammable materials.
• No liquids or conductive materials must get into the instrument. If this happens to be the case, the instrument is to be
disconnected from mains power immediately and examined, cleaned, and eventually repaired by a qualied person (that
would be us).
• Never expose the instrument to temperatures above +50 °C or below -10 °C. Before powering up, the instrument should
have a temperature of at least +10 °C. Do not place the instrument in direct sun light. Do not install the instrument near heat
sources such as radiators, open re places, or thermo-nuclear testing sites (or power plants that would employ people like
Homer Simpson).
• Keep the top of the instrument clear in order to warrant proper ventilation, otherwise the instrument may overheat and
malfunction.
• Never place heavy objects such as beer crates, trucks, or mothers-in-law on the instrument.
• Before moving place with Quadrantid Swarm, make sure the unit is disconnected from other devices (external controllers,
mixers etc.). If not, watch for cables and other pit-falls. Funny lms can be uploaded to the internet.
• Transport the instrument carefully, never let it drop or be rude to it. Make sure that, during transport and while in use, the
instrument is properly supported (no pizza cartons or king-size buckets of chicken-wings) and cannot fall or slip from your
(possibly greasy) ngers – people might get injured and, even worse, sue you for this.
• Never use the instrument in the immediate proximity of interfering electronic devices (e.g. computers and monitors, power
supplies, speakers, ux compensators, or hadron colliders) since this might cause Quadrantid
Swarm to behave erratically – and may result in corrupted memory data as well.
• Before cleaning Quadrantid Swarm, make sure the unit has been unplugged.Use a soft, dry cloth only to clean Quadrantid
Swarm. Never use any liquids, abrasive cleaners or cleaners containing solvents such as alcohol, terpentine, or other spirits
(such as Scotch Single Malts in cask strength).
• e instrument is to be shipped in the original packaging only. Any instruments shipped to us for return, exchange, repairs
covered under warranty, update or examination must be in their original packaging! Any other deliveries will be rejected.
erefore, you should keep the original packaging and this user documentation – if only as a doorstop.
• e instrument may only be used for the purpose described in this operating manual. Due to safety reasons, the instrument
is never to be used for purposes other than musical (e. g. disintegrating neighbours, bending the space-time continuum,
impressing girls etc.).
• When using the instrument in Germany, ACHTUNG: the appropriate VDE standards are to be obeyed. e following
standards are of special and utmost importance: DIN VDE 0100 (Teil 300/11.85, Teil 410/11.83, Teil 481/10.87), DIN VDE
0532 (Teil 1/03.82), DIN VDE 0550 (Teil 1/12.69), DIN VDE 0551 (05.72), DIN VDE 0551e (06.75), DIN
VDE 0700 (Teil 1/02.81, Teil 207/10.82), DIN VDE 0711 (Teil 500/10.89), DIN VDE 0860 (05.89), DIN VDE
0869 (01.85). VDE papers can be obtained from the VDE-Verlag GmbH, Berlin. German readers will know
where to turn to, all others do not really need to bother.

Paraphonic synthesiser
We designed the QS for immediate use without having to worry about complex patching, so pre-patching
is used to make connections in logical places. Some of these are highlighted using arrows, particularly the
modulation sources and connections, the audio routing hasn’t been highlighted to keep the design clean but
as expected runsfrom mixer, to lter, to reverb then to VCA.
e VCO section is Digital, while the lters, the VCA and the spring reverb are analog.VCOe QS oers 8
dierent VCO models and an additional percussive soundthe VCO has 3 parameters, Freq, Spread Character.
e Percussive sound has one parameter, perc which determines the length of the percussion decayFreq :
controls the base pitch of the VCOs. It can be modulated by the CV in input associated to it’s attenuator :
