DiGiCo SD8: “Into overdrive and beyond…”

The SD8 is a particularly versatile console with the same Stealth Digital Processing and floating point Super FPGA technology seen in the flagship SD7. The SD8 offers a truly superlative performance at a competitive price, something which will appeal to engineers across the board.

Scratching the surface

There are two versions of the SD8: a 37-channel version, which boasts three banks of 12 motorised faders and one master fader; and the SD8-24, which has all the same power and functionality but in a smaller frame comprising 24 main channel faders and a master fader.

At the heart of each console’s worksurface is a 15-inch, high resolution TFT LCD touch screen with backlit display. Through this user-friendly interface, any bank of 12 faders can be instantly assigned as input or output channels, allowing all 36 main faders to control inputs if desired; equally, any bank of 12 can also be assigned to the touch screen for fine-tuning.

In addition, the SD8 benefits from dedicated multi-function control knobs and electronic labelling.
