HX3 mk3/mk4 additional info

New HX3 mk3 Board is equipped with stereo Leslie® simulation, secondary MIDI input and configurable mono audio output jacks.

On factory default, menu item "Jack Config A" yields bass pedal on left (inner) audio jack, plain organ signal (like G-G on B3 AO28) on right (outer) audio jack. "Jack Config B" yields stereo Leslie® simulation on both jacks with added dry bass pedal signal. Both configurations may be changed to any combination with "AudioJ Conf A" and "AudioJ Conf B" menus (scroll down to access).

Both MIDI DIN jacks are wired by internal jumpers as MIDI inputs with merge. Please disregard lettering on back. You may use a MIDI master keyboard and a additional MIDI keyboard or MIDI drawbar controller. Original MIDI OUT configuration may be obtained by internal jumper setting. Also, MIDI phantom supply may be routed to left MIDI input by placing two additional jumpers.
