The solenoid control system for each and any solenoid.
Solenoids shift slides and couplers in all kinds of organs. Some must move swiftly, some gradually. They're powered briefly, but occasionally all the time. Direct Connect can control them all from one single point.
Complete control minus confusion
In short, an organ's every solenoid has a control card. Each one is colour-coded according to its use, from ordinary on/off switching to luminous control. Every card then fits in a simple ready-made rack.
To change a circuit's use, just change a card. To adjust the strength and degree of a solenoid's pull, stay at the rack and do it there. The same with wiring: to confirm a stop action input or check the output circuits, just look at the tell-tale LEDs.
Voltages are 12 to 26-volt operation as standard..
