Our take
History & design
The SD7 topped DiGiCo's SD range at its 2008 launch. It brought the Stealth Digital Processing engine to large scale, using Super FPGA components backed by TigerSHARC DSPs in a dual-engine architecture for redundancy. It handles 253 input channels, 128 aux/sub-group buses, a 32 x 32 matrix, 36 control groups, 48 stereo effects and 32 32-band graphic EQs, identically at 48 or 96 kHz.
The work surface is arranged around three 15" touchscreens, each above a bank of 12 faders, plus 16 assignable faders in the centre, for a total of 52 motorized 100 mm faders. Local I/O (12 analogue inputs and outputs, 12 AES) is complemented by four redundant MADI ports per engine and an Optocore loop, allowing preamps to sit in remote SD-Racks over fibre: up to nearly 1,400 I/O connections on a single loop.
Designed for mission-critical reliability, the SD7 relies on redundancy at every stage: dual removable engine, hot-swappable PSUs, doubled MADI and Optocore. Compatible with the Waves ecosystem (SoundGrid) and with Dante via expansion cards, it fits into every touring infrastructure.
The brand's long-standing flagship, the SD7 was later carried forward and modernised by the Quantum range (Quantum7), which keeps the same ergonomics on an updated FPGA platform.
