The Quantum 338 sits in the middle of DiGiCo’s Quantum range, above the SD12 and Quantum 225 and below the larger Quantum 7 and the current flagship Quantum 852. It brings Quantum-generation processing — Mustard channel strips, Spice Rack, Nodal Processing — to a console that still fits many FOH positions. This review is based on DiGiCo’s published specifications.
Key specifications
| Specification | DiGiCo Quantum 338 |
|---|---|
| Input channels | 128 (48/96 kHz) |
| Busses | Up to 64 aux / group busses, LR/LCR/LCRS/5.1 master |
| Matrix | Up to 24 × 24, fully processed |
| Faders | 38 × 100 mm touch-sensitive motorised (three banks of 12 + 2 assignable) |
| Screens | 3 × 17″ high-brightness touchscreens, plus 70 TFT channel displays |

| Size / weight | 1595 × 805 × 482 mm, 70 kg |
Strengths
Processing depth. Mustard channel strips, Spice Rack plug-in-style FPGA processing and Nodal Processing come as standard, alongside large pools of dynamic EQ and DiGiTuBes. Engineers can shape and route far more than on the SD range.
Surface and visibility. Three bright 17″ screens and 70 channel displays make it easy to see what each fader is doing, even outdoors.
Recording and networking. Built-in USB MADI recording, multiple MADI interfaces, AES and dual DMI slots cover multitrack recording and integration with Dante or other networks through cards.
Limits
- Size and weight: 1.6 m wide and 70 kg (198 kg in its flightcase) — plan the FOH position and logistics.
- Not the top of the range: for the largest productions DiGiCo offers the Quantum 7 and Quantum 852.
- Price: a significant investment once stage racks and cards are added; request current quotes.
Quantum 338 vs SD12
The SD12 offers 72 channels, 36 busses, a 12 × 8 matrix, 26 faders and two screens in a 42 kg frame; the Quantum 338 offers 128 channels, 64 busses, a 24 × 24 matrix, 38 faders and three screens at 70 kg, plus Quantum processing. If the SD12’s channel and bus counts are enough and space is tight, it remains the pragmatic choice — see our DiGiCo SD12 review.
