Avid S6
The modular hardware control surface used in professional film and television post-production mixing suites to control Pro Tools sessions for dialogue, music, and effects mixing — including Dolby Atmos.
What it is
About Avid S6
The Avid S6 is a professional hardware mixing control surface for post-production audio — used in the dub stages and mix suites where dialogue, music, and effects are combined into the final soundtrack for film, television, and streaming productions. It is not a standalone audio device: the S6 is a control surface that connects to Pro Tools (running on a separate workstation) and provides a physical interface — faders, encoders, touchscreens, and monitor controls — that allows a re-recording mixer to operate a Pro Tools session with the ergonomic fluency of a hardware mixing environment rather than a mouse. The S6 is designed specifically for Dolby Atmos immersive audio mixing, with integrated 3D panning controls and bed/object routing that would be extremely slow to operate with a mouse in a complex Atmos session. The S6 is modular: studio managers configure it from fader, process, and display modules to match their budget and room size. An M10-based system (smaller master module) starts at approximately $22,000 and controls up to two Pro Tools workstations simultaneously; an M40-based system starts at approximately $44,000 and scales to 64 faders, controlling up to eight workstations — appropriate for a large-format film dub stage mixing a full Atmos 7.1.4 or 9.1.6 stem session. In UK and US commercial and broadcast post-production, the S6 has largely replaced the ICON D-Control and D-Command systems it succeeded, and is the dominant control surface in new-build mix suites. Audio Engineers and re-recording mixers working at feature film level are expected to be fluent on the S6 as the standard tool of their environment.
What you can do with it
Capabilities
Recall a mix session on the Avid S6 — loading the Pro Tools session and confirming that the S6 surface maps all fader positions, EQ settings, and monitor level from the last session state, so the re-recording mixer can pick up exactly where the previous session ended without manually setting up fader assignments
Ride dialogue levels during a review pass using the fader bank — identifying the dialogue stems in the Pro Tools session, assigning them to the S6 fader bank, and manually riding the faders in real time as the picture plays to achieve the broadcast target loudness (-23 LUFS EBU R128) while preserving the dynamic range of the original performance
Pan an Atmos object using the S6's integrated 3D panning touchpad — selecting a sound effects stem designated as an object in the Pro Tools Atmos renderer, using the S6's joystick panner to move the object from the front left speaker position overhead and behind the listener across a 5-second sweep, and confirming the movement on the Dolby Atmos Renderer binaural monitoring fold-down
Set up a monitor path on the S6 for a final mix review — configuring the monitoring section to switch between the full 7.1.4 Atmos bed, a stereo fold-down, and a mono TV speaker simulation, so the re-recording mixer can check the mix across all delivery formats from the S6 monitor section without moving to the computer
Recall a Total Recall snapshot for a version delivery — saving the current full mix session state as a snapshot, switching to the M&E (Music and Effects) version of the session, confirming the S6 surface reflects the M&E stem configuration, and returning to the full mix snapshot to deliver the main programme version
How to learn it
Learning Resources
Avid S6 product documentation and video resources (avid.com/products/avid-s6/resources) — official Avid resources covering surface setup, Pro Tools integration, fader bank configuration, and Atmos monitoring; the authoritative starting point
Avid Learning (learn.avid.com) — Pro Tools post-production courses covering S6 integration in professional mixing workflows; required reading alongside surface-specific documentation
Assisting in a professional post-production dub stage — the fastest route to S6 fluency; observing how re-recording mixers configure sessions, manage recall, and use the Atmos panning hardware is not replicable from documentation alone
Sweetwater and Professional Audio Design product training sessions — authorised Avid resellers periodically run in-person and online S6 workflow training; valuable for understanding modular configuration options before specifying a suite build
Pro Tip
Understand Total Recall before your first session on an S6. Total Recall saves and restores every physical parameter of the S6 surface — fader positions, EQ, panning, monitoring configuration — so a session can be recalled from any saved state across multiple engineers and multiple days. On a film mix lasting four to six weeks, Total Recall is what allows a different engineer to jump in for a day without destroying the established mix state. The first thing a professional re-recording mixer does at the start of any session is confirm Total Recall is active and the last snapshot has loaded correctly.
