HX3 mk2 board (spare part)

Spare part only, not recommended for new designs!

Older Version with 4 channel audio output, but no extension board connector. Suitable for current HX3.4 firmware 4.26.

This board offers the older sound engine with full B3 functionality. We would like to point out that the built-in Leslie simulation is older and cannot quite keep up with our current HX3.6 boards; if you have special requirements regarding the Leslie simulation, we recommend an external effects device such as the Neo Instruments Ventilator.

Please note: The Drawbar boards matching this hardware are no longer available. However, you can continue to use your own drawbar pots or those already present in an organ. The board can also be used as a pure MIDI expander connected to a master keyboard. A backpanel is included.

Please ask for options before ordering. Licence of defective board may be re-used; price will be discounted by 100 Euro if old board is sent to us.

Hammond B3 emulation module HX3, completely stand-alone, for control via MIDI or connected keybeds. Version with stereo rotary simulation installed. Requires only a power supply (e.g. plug-in power supply) to function, if controlled via MIDI. Alternatively connection of drawbars (sliders), pots, switches and buttons directly possible, keyboards via scan boards (see accessories).

HX3 mk2 module tested, current firmware installed, used (return from our upgrade action). With stereo Leslie simulation and second MIDI input (adjustable as output via jumper).

Connection of 18 drawbars (9 per manual) plus 3 drawbars bass 16', 8' and bass sustain (DC controlled inputs 0 to 3.3V), plus potentiometers Leslie Amp 122 Volume, Tone (also DC controlled). Input for swell control voltage or direct connection of a Yamaha FC-7 or similar possible (jack socket). For each function a pushbutton (not latching) with LED or a switch can be used (also mixed). Since all pushbuttons/switches switch to ground, the wiring is especially easy.

Please note: The drawbar boards matching this hardware are no longer available.
