3. THE REAR PANEL
All connections are found on the back panel of the Crumar Mojo Desktop. From left
to right, on the upper row we find:
– Swell Pedal input: this is a TRS Jack that receives an expression pedal with a
10K to 50K linear potentiometer. This is mainly used to modulate the “Swell”
(expression) pedal of the tonewheel organ.
– Foot Switch input: this is a TRS Jack that receives Crumar's dual foot switch
used for switching the Rotary Simulator effect speeds. Please refer to Crumar's
website for informations about the accessories.
– Two parallel MIDI inputs. These two MIDI inputs are internally merged, so you
can connect two traditional MIDI keyboards and have them send on two
different channels (usually 1 for upper and 2 for lower) so you can play the two
manuals of the tonewheel organ simultaneously without having to use an
external merging unit.
On the bottom row we have:
– A/C Adapter input. We recommend to use the adapter that comes with the
unit. Should you lose your adapter, since this is a standard connector, you can
replace it with a different adapter type that has a 2.1 DC jack with center
positive, and carries at least 2000 mA of current at 9V or 12V. If you're uncertain,
call your dealer or contact Crumar.
– Power button. Make sure this is pushed in to rock the world.
– Two SYSTEM USB ports. These are USB-host ports that can accept external
devices. In the case of the Mojo Desktop, they can accept Class-compliant USB-
MIDI devices such as master keyboards or other controllers, or USB flash drives
for importing/exporting Programs and Banks or for performing the Firmware
update.
– MIDI I/O USB: this is a Device type USB port, used mainly to connect the Mojo
Desktop to your computer for MIDI input and output connectivity.
– Audio outputs L & R: these are TRS Jacks that carry balanced audio signals.
– Headphones: connect your headphones here.
