Product Description The 9100-31504-20 is a precision replacement fader assembly specifically engineered for the Digidesign ICON D-Control console system. As a high-performance, motorized component, it provides tactile control over Pro Tools mixer channels with professional-grade accuracy and smoothness. The fader is touch-sensitive, allowing for instant automation override and selection, and is built to withstand the heavy duty-cycles required in high-end recording and post-production studios. This specific revision is designed to maintain the consistent feel and ballistic response characteristic of the flagship ICON series.
Product Applications This fader module is used exclusively as a critical spare part for the maintenance and repair of ICON D-Control Main Units and Fader Expansion Packs. It is found in premier recording studios, broadcast facilities, and film scoring stages worldwide where D-Control surfaces remain the primary interface for Avid Pro Tools HD/Ultimate systems. It is essential for engineers who rely on physical tactile feedback for precise level balancing and automation writing.

Operational Precautions
- Calibration: After installation, perform the “Fader Test and Calibration” routine from the D-Control Utility menu to ensure the fader tracks correctly with the digital on-screen fader in Pro Tools.
- Cleaning: Use only compressed air and specialized fader lubricants (like DeoxIT FaderLube) if necessary; never use standard contact cleaners or WD-40, as these will destroy the conductive plastic tracks.
- ESD Safety: When replacing the fader, ensure the console is powered off and you are grounded; static discharge can damage the touch-sensitivity circuitry on the fader board.
- Ribbon Cable Handling: Ensure the ribbon cable is fully seated and the locking clips are engaged; a loose connection can lead to “chattering” fader movement or loss of touch sensitivity.
