HX3 Drawbar Expander 5
Jack Connections
HX3 Drawbar Expander connectors on back panel, left to right:
SWELL PEDAL
¼” stereo jack. Expression pedal input is compatible with Yamaha FC-7
and similar expression pedals (direct connection preferred for speed/accuracy, but may
also be remote controlled by MIDI control change, controller 11). Plug connection: Sleeve =
ground / potentiometer start, ring = potentiometer tap, tip = potentiometer end.
FOOT SWITCH
¼” stereo jack. Single or double footswitch controls simulated rotary speed
as well as external rotary cabinet speed: SLOW/FAST on plug tip, RUN/STOP on plug ring.
Please use latching foot switches; momentary (button type) switches are not supported. If
single footswitch is used, Rotary is always on RUN (no plug ring, input grounded by plug
sleeve).
MIDI IN 1
Accepts MIDI data from master keyboard 1 or bass pedal
MIDI IN 2
Accepts MIDI data from master keyboard 2 or bass pedal
9V DC
Use stabilized DC wall wart 9 to 12V with at least 500mA current output, inner/outer
plug diameter 2.1/5.5 mm on DC input jack. Polarity: Plus on inner tip.
ROTARY SIM L
Audio output left channel of internal rotary simulation
ROTARY SIM R
Audio output right channel of internal rotary simulation
BASS
Separate audio output for bass pedal sound
MAIN
Plain Organ output, as sent to external Leslie® speaker, without tube amp
simulation and rotary effect
USB
USB B-type connector for MIDI over USB, for updates and configuration by HX3.5
Editor application. USB and MIDI IN 2 cannot be used simultaneously.
MIDI OUT
Sends MIDI data of HX3 Drawbar
Expander’s own controllers
HEADPHONE
Stereo output of internal rotary simulation, headphone amplifier
ROTARY STATUS
3 LEDs indicate status of external Leslie ®, green = on, red = slow,
yellow = fast
EXTERNAL ROTARY
Standard 11-pin Leslie® speaker connector. Not suitable for 9-pin
Leslie® speakers with passive adaptor due to different polarity of switching voltages. We
recommend using a Leslie® preamp for 6-pin and 9-pin Leslie® speakers.
