Originally developed by Electronic Instrument Service, the EIS-147A provides a silent and extremely reliable alternative to the old style electromechanical relays originally supplied in Leslies utilizing 147A type amplifiers. Ideal for use in studio, church, and professional applications where quiet switching or ultimate reliability is essential.
These units are fully compatible with existing stock Leslie control circuits and therefore require no changes at the console for standard operation.
For standard 2 speed (fast / slow) operation, EIS equipped Leslies may be freely mixed with Leslies in the same family that still use an original electromechanical relay.
For those wishing for more than basic relay replacement, the EIS-147A relay has the capability to completely stop the rotors without additional wiring between the console and the Leslie. To utilize this feature, a suitable 3 position switch must be installed at the console.
• Easy installation
• Eliminates electrical and mechanical switching noise
• Capable of adding stop function to Leslie
• Microprocessor based design provides advanced features, while retaining simple operation
• Fully enclosed
