6 Connections Dave Smith Instruments
Connections
AC Power Inlet— Accepts 13.5VDC at 1400mA from the supplied external
power supply. The tip of the plug is positive (body is ground).
USB— For bidirectional MIDI communication with a computer. The Prophet 12
is a Class Compliant USB device and does not require additional drivers when
used with Mac OS or Windows. The Prophet 12 transmits and receives data via
USB, but does not transmit audio.
Note: MIDI In and USB should not be used at the same time, as overlap-
ping messages from different sources may cause the Prophet 12 to respond
unpredictably. MIDI Out and USB can be used at the same time and transmit
the same data.
See Using USB on page 47 for more information.
Sustain— Accepts a momentary, normally open or normally closed footswitch
to control sustain or to turn the arpeggiator on and off. See “Sustain Footswitch”
under Global Settings on page 10 for more information.
Pedal 1 and Pedal 2— Accept a standard expression pedal that has a variable
resistor on a TRS (tip-ring-sleeve) ¼″ phone plug. For more information, see
“Pedal 1 Function” and “Pedal 2 Function” in Global Settings on page 10.
MIDI In, Out, and Thru— Standard 5-pin MIDI DIN connectors.
