Display PDU Home Screen

The Opus-Two Stand-Alone Products allow existing organs that are not equipped with the Opus-Two ICS to have access to some of the features offered in the Integrated Control System (ICS).

The Pedal Divide Unit (PDU for short) includes a dedicated VFD display and all necessary software/hardware to make the function work with ANY control system.  The unit can be built to support positive-common and negative-common stop controls or key controls, and has a built in reversible engine should a piston (or momentary button) be used to turn the function on or off.   Pedal Divide Position is typically stored in a set of stops in the existing combination.  Only 8 stop spaces are needed in the general memory to store all the features of the PDU on general pistons (feature on/off and pedal divide position).  No special interface boards need to be provided by the C/A manufacturer – Opus-Two connects to the existing sense and coil wiring.  If the existing combination action is not capable of controlling 8 additional stops (for whatever reason), the PDU has a built-in combination action capable of storing divide points across a nearly-unlimited number of pistons in a nearly-unlimited number of memory levels.

Detailed installation instructions are included to assist the organ builder with product installation.  The cards come panel-mounted and pre-wired: simply wire the keying and supply power.  The display unit and control buttons connect back to the card panel with our simple 3 wire connection.

The most recent revisions to this unit have significantly cut cost and have made the unit available for even more customers.

Technical Information:

The relay manufacturer must change the relay to allow two different sets of pedal keys.  The first set drives keying to the stops in the pedal division.  The second set of keying drives the “to pedal” couplers.  This is most commonly accomplished by other relay vendors by defining the “to Pedal” couplers as “to Solo” (or some other unused keyboard) and then treating the coupler/pedal keys as a “Solo” keyboard.

If an external C/A is used, an additional 8 stops must be added to the hardware/software as if you were adding 8 stop action magnets.  You can, in fact, simply tell the manufacturer that you are adding 8 additional drawknobs or stop tablets.  Opus-Two reads and writes to those outputs to “fool” the combination action into thinking that real tabs are attached.

Range: If manually setting the divide point, the divide point can be set to any pedal from C#1 – F#3.  To set the pedal divide point manually, simply hold the first note you wish to be in the upper split and press the “Pd Div Set” button.  The divide point is then set, and will save to any general pistons.  Auto-Tracking (typically used for improvisations) will work for D#1-E3.  To activate the auto-tracking feature, press the “Auto Tracking” button.  The display will update to indicate auto-tracking in progress.

To Freeze the Pedal Divide Point at its current location (preventing auto-changes or changes from pistons), press the “Freeze” button.  The display will update to indicate the divide point is frozen.
