Defender DC-147 Low Voltage Switch Interface


Modern safety upgrade for console organs.

SKU: N/A Categories: , ,


The Defender DC-147 is a modern safety upgrade to any console organ that is compatible with a 147-type Leslie®. Intentionally designed for easy installation, the DC-147 converts the potentially lethal AC voltage on the speed switch to a safe 12VDC.

Installation is as simple as rewiring the speed switch and inserting the DC-147 between the switch and the Leslie 147 connector. Defender takes over pin 2 of a 6-pin 147 connection and taps AC on pins 3 and 4. Every Defender ships with 1′ each of blue, yellow, and gray wire to add to your existing connection, if needed.

BookerLAB offers a few configurations for the Defender, with an option to include a 1-foot 1/4″ TRS jack accessory that can be easily rewired for either 2- or 3-speed usage. Defender can also be utilized in a console as a “connect kit”.
