Designed to fit Avid's S4 series consoles, the Avid Control Strip Module (CSM) is one of the three core modules included in all S4 base configurations.
 
Giving you control of track levels, plugins, and other parameters through eight channel faders, the CSM makes mixing more like, well, mixing. With motorized faders, 32 top-lit knobs (four per channel), solo, and assign buttons, you'll enjoy the intuitive feel of a timeless old school mix desk. But make no mistake, this is state of the art, and you can outfit your console with up to 3 CSMs to support a 24-fader configuration.
 
The S4 series is a semi-modular digital console designed to give smaller facilities a budget-friendly way to bring the power of Avid's industry-standard S6 mixing system to their projects.
 
The S4 system starts with your choice of base systems consisting of up to 3 channel strip modules (24 faders max), a master touch module, a master automation module, and a frame.
