Digico SD8–24 Digital Mixing Control Surface

DiGiCo SD8-24: “Into overdrive and beyond…”

The SD8-24 is a particularly versatile console with the same Stealth Digital Processing and floating point Super FPGA technology seen in the SD7. It offers a truly superlative performance at a competitive price and comes in an even smaller footprint than the SD8, something which will appeal to engineers across the board.

The SD8-24 has all the same power and functionality as the 37-fader SD8, but in a smaller frame, comprising 24 main channel faders and a master fader.

At the heart of the 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 24 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 SD8-24 benefits from dedicated multi-function control knobs and electronic labelling.

Under The Hood

Like the SD8, the Digico SD8–24 boasts 60 processing channels at 48kHz/96kHz, all of which are Flexi Channels (configurable as either mono or stereo), which is the equivalent of 120 channels of full DSP processing.

Standard channel processing, whether inputs or outputs, includes Channel Delay, Single and Multi Channel Presets, Dual insert points, Hi- and Lo-pass filters @ 24dB/octave, four-band parametric EQ with band curve selection, DiGiCo’s DYN 1 (Compressor, De-esser or Multiband Compressor) and DYN 2 (Gate, Compressor or Ducker).

The console also benefits from 190 Dynamic EQ processors, all of which can be assigned to any of the input or output channels. These powerful processors offer dynamic processing on each of the four standard parametric bands, plus there are also 190 Multiband Compressors and 190 DiGiTuBes; and no matter how the console is set up, the user won’t lose any resources, as all the channels are equipped to provide the same high quality signal path and feature set.

The master section incorporates 24 gangable 32-band graphic EQs, 16 stereo effects (selectable from a palette of 33), and 24 control groups (VCAs); and using snapshots, engineers can switch between complete configurations in any live environment easier than ever before, be it at rehearsals, during system setup, or even at a show.

In addition, we’ve included 24 Flexi busses, all of which are assignable as mono/stereo groups or auxiliary busses; and in addition to these busses, for further configurability, we’ve provided a 16 x 12 output matrix, dual solo busses, and a Master buss. Essentially, users have the equivalent of 67 busses of DSP at their disposal.

Unlike all other digital console manufacturers, you don’t lose Aux or Group Busses when using the Matrix as they are in addition, including the Master buss.

I/O

The Digico SD8–24 has exactly the same local I/O as the SD8: eight mic inputs, eight outputs, eight mono AES I/O, and two MADI connections.

The console comes as standard with a MaDiRack which is an 8U fixed 48 input with eight analogue outputs, with the ability to increase these outputs to 24 with any combination of analogue AES/EBU or Aviom.

As with all DiGiCo consoles, it can also connect to any DiGiCo rack.

There is also a factory fit Optocore option which allows for connectivity to all DiGiCo racks and consoles in a redundant loop.

Get instant access to 32 fully integrated low-latency Waves stereo MultiRacks, each with up to eight plug-ins per rack, by fitting an optional DiGiCo SoundGrid module linked to external SoundGrid or DiGiGrid servers, giving a total of 128 additional I/O.
