The DiGiCo S-series (S21 and S31) was built to bring the DiGiCo name, sound and workflow to engineers who can’t stretch to a Quantum or SD flagship. With a bold multitouch interface and Stealth Digital Processing, it’s a different animal from the prosumer crowd. Here’s an honest round-up of what owners and engineers report.
Where these takes come from
A synthesis of recurring opinions across English-speaking communities (r/livesound, Gearspace, ProSoundWeb, Sound on Sound forums) and S-series owners. For the flagships, see our DiGiCo Quantum/SD guide.
What owners love
DiGiCo sound and quality at a lower price
The headline: the brand’s clarity and processing pedigree in a more attainable desk. Owners feel they’re getting « a real DiGiCo, » not a watered-down one.
The multitouch interface
The big, gesture-driven touchscreen draws praise for a modern, fast feel once you adapt — a genuinely different way to mix.
Compact and well-built
A small footprint with DiGiCo build quality, plus optical/stagebox expansion for serious systems.
What owners flag
1. The touch-centric workflow divides opinion
The most-discussed point: the S21 in particular leans heavily on the screen with few physical controls. Some love the gesture workflow; others find it slower than knobs-and-faders for fast live moves.
2. Price above the prosumer tier
It costs more than an X32/SQ — you’re paying for the DiGiCo name and engine.
3. Less power than the flagships
Channel count and processing sit below the Quantum/SD desks, as expected at the price.
4. I/O via stageboxes
Plan (and budget) for stageboxes to build out your input count.

Where the S-series fits
It’s the entry point into the DiGiCo ecosystem for engineers who want the brand, sound and UI without flagship money. If you prefer hands-on faders and value, the A&H Avantis is a strong alternative; see also our DiGiCo vs Avid comparison.
My honest take
The S-series is a genuine, affordable way into DiGiCo — the sound and that striking multitouch UI for far less than a flagship. The touch-first workflow is the one thing to try before you buy: it clicks for some and frustrates others. See our complete console guide.
Specs and a typical rig
Both S-series desks use DiGiCo’s Stealth Digital Processing: the S21 offers 48 input channels and 16 buses on a dual-touchscreen surface with relatively few physical controls, while the S31 keeps the same engine but adds a full bank of motor faders and rotaries for hands-on operators. Optical and MADI/stagebox options let either desk scale into a serious touring or install system well beyond its local I/O.
The one thing owners repeat is to trial the S21’s gesture-driven, screen-first workflow before committing — engineers who mix fast off physical controls sometimes prefer the S31’s extra faders, while others adapt quickly and love the multitouch immediacy. It’s less about capability than personal working style.
On price, the S-series sits above the X32/SQ prosumer tier but well under the Quantum and SD flagships — the intended « entry into DiGiCo » position. Owners frame the value as buying into the DiGiCo sound, UI and expansion ecosystem at a reachable price, with stageboxes budgeted separately as the input count grows — which owners recommend planning from the outset rather than discovering mid-build.
FAQ
Is the DiGiCo S21 a « real » DiGiCo?
Yes — it uses DiGiCo’s processing and sound philosophy in a more affordable package, not a stripped-down sub-brand.
How is the workflow?
Multitouch and gesture-driven, with few physical controls on the S21. Great for some; others prefer more knobs and faders for live work.
S21 or S31?
The S31 adds more faders and physical control; the S21 is more screen-centric. Choose by how hands-on you want to be.
Does it need stageboxes?
Typically yes, to expand input count — factor them into the budget.
