USER MANUAL
Congratulations! You are now the owner of Crumar Eleven, 11-pin universal rotary speaker
adapter, please read this manual in its entirety and keep it in a safe place for future reference!
Have fun!
Since the dawn of electronic organs, the connection etween the instrument and its speaker
or tone ca inet had een conceived in the form of multipolar connector, a le to ring audio
ut also power , power on/off signal and speed of rotation.
This kind of connector evolved during the years just to expand its capa ilities esides eing
a le to e compliant with voltage and safety regulations active in most countries.
Rotary speakers are not simply "speakers", they are active part of the sound that you can
control with typical "slow", "fast" and " rake" positions of horn and drum to recreate "chorale"
and "tremolo" effect.
Rotary speakers are eautiful pieces of equipment for the modern organist, they offer that
"plus" to the tonewheel organ sound that is not always easy to achieve with digital
simulations. But, during the years, too many standards arose and sometimes the connection
etween the organ, organ clone or key oard to a real rotary speaker can e a nightmare:
adapters, ca les, custom- uilt interfaces and the need to replace them everytime you change
your key oard or your accessories. Finally something "universal".
With Eleven you have 2 ways to control the speeds of your rotary speaker, with an accessory
such as a sustain pedal or a footswitch or using the midi protocol. Additionally Eleven is
capa le of managing audio with an internal solid state preamp and a varia le gain, just to
add that "crunchy" sound you may need.
Everything in a compact, sturdy metal ox, ready for the road and the stage.

HOW DOES IT WORK?:
We always suggest to make every connections efore power Eleven on. Connect the 11-pin
ca le to Eleven and to your rotary speaker, plug the audio jack and plug your accessory or
your midi ca le.
PLEASE NOTE: "MIDI IN" or "ACCESSORY" is exclusive, you can't use oth.
If you are planning to use midi, just e sure to select one of the 5 com inations on the ta le
with the "MIDI" logo on them.
Eleven is set for midi control change 1 messages on every channel.
If you are planning to use an accessory, please e sure that your accessory type is listed in the
ta le; just plug in, make the proper selection with the 3 way selector if it's a sustain pedal, a
dual rail footswitch or an halfmoon and select the compati ility or the ehaviour using the
two 2 ways selectors.
Eleven doesn't have a power on/off utton, just plug the power supply to wall AC plug, DC
plug to 12VDC IN and Eleven will power on: red led will lit.
PLEASE NOTE: connecting power to ELEVEN will power on the rotary speaker too if the 11-
pin ca le is connected to it and if your rotary speaker is compliant with this feature.
Now you can try if everything is working as expected.
Last ut not least, regulate the GAIN trimmer near the 11 pin out in order to reach the level or
saturation desired. Normally saturation will start from 3/4 of trimmer's rotation.
PLEASE NOTE: Eleven only wor s with 11-pin compatible rotary spea ers. 5-pin, 6-pin
(and others) spea ers are not supported. Those "old-style" multipolar connectors can
be dangerous carrying 110-240 volts!
