DiGiCo S21 Digital Mixing Console Overview

48 Flexi Input Channels

The S21 provides up to 48 Flexi Input Channels, giving engineers the flexibility needed for complex live productions. The large channel capacity allows the console to handle multiple microphones, instruments, playback sources, and other audio inputs without requiring an unnecessarily large control surface.

16 Flexi Busses + LR + 4 Matrix

The console includes 16 Flexi Busses together with LR and four Matrix outputs. This flexible bussing architecture makes the S21 suitable for front-of-house mixing, monitor applications, broadcast workflows, corporate events, theater productions, and houses of worship.

21 Touch-Activated Moving Faders

The S21 features 21 touch-activated moving faders, arranged as two banks of 10 faders plus a dedicated master fader. Motorized faders provide tactile control over channels and buses while allowing engineers to quickly recall different sections of a mix.

Dual 10.1-Inch Multi-Touch Displays

Two 10.1-inch multi-touch screens provide an intuitive interface for controlling the console. The dual-screen design makes it easier to access channel parameters, routing, processing, metering, and other mixing functions while maintaining a compact physical footprint.

96kHz Processing

The DiGiCo S21 uses internal 96kHz processing and a 40-bit floating-point audio engine. This provides the digital processing platform required for professional live sound and other demanding audio applications.

DMI Expansion

Two DMI card slots provide additional connectivity options and allow the console to be configured according to the requirements of different audio systems. Depending on the installed cards and system configuration, users can integrate technologies such as Dante, MADI, Waves, and other compatible digital audio solutions.

This makes the Used DiGiCo S21 Digital Mixer particularly attractive to buyers who need a flexible console that can adapt to an existing digital audio infrastructure.

Onboard Inputs and Outputs

The S21 includes two onboard mic/line inputs and two line outputs using XLR connections. These connections provide convenient local I/O while the console’s expansion capabilities allow users to build larger systems using compatible DiGiCo D-Rack, MADI, DMI, and stagebox solutions.

For larger productions, the S21 can therefore become the central control surface of a more extensive digital mixing system.

USB Recording and Playback

The DiGiCo S21 also supports USB recording and playback for two-track applications. This can be useful for recording a stereo mix, playing back reference material, or incorporating recorded audio into a production workflow.

Snapshot Automation and Spill Groups

Snapshot automation allows engineers to save and recall different console configurations during a production. This is particularly useful for theater, live events, houses of worship, and other applications where the mix needs to change quickly between scenes or sections.

Spill groups also provide an efficient way to organize and access related channels, helping engineers manage complex mixes from the S21’s compact control surface.

DiGiCo D-Rack and Expansion Compatibility

One of the major advantages of the S21 is its ability to work with compatible DiGiCo expansion equipment. The console can be integrated with DiGiCo D-Rack, MADI, DMI interfaces, and compatible stageboxes to create a larger digital audio system.

For buyers who require additional stage inputs and outputs, pairing the console with an appropriate D-Rack or digital I/O solution can create a powerful professional mixing rig.

If you are purchasing this console as part of a larger production system, we recommend confirming the required DMI card, stagebox, and connectivity configuration before completing the purchase.
