Overview
The DiGiCo SD-Nano Rack is the smallest SD-Series stage rack: a 2U box with two SD card slots for up to 16 inputs and 16 outputs with digital cards, or 16 analogue ins, 16 outs or 8 in and 8 out. It is an optical only rack with no MADI ports, and this version ships unloaded with the Optocore multimode interface on ST fibre connectors.
Because it uses the same Stealth FPGA platform and card format as the SD-Rack, it slots into an existing Optocore loop alongside bigger racks, with up to 14 racks per loop or 28 on a dual loop. It runs from 44.1 to 192 kHz, supports Gain Tracking and has two internal redundant PSUs.
Highlights
- 2U, 2 card slots, up to 16 in and 16 out
- Optocore fibre on ST connectors, 1G or 2G
- Optical only rack (no MADI)
- 44.1 to 192 kHz operation
- Two internal redundant PSUs
- Gain Tracking support
Compatibility
Works with: DiGiCo SD9, SD11, SD12 and Quantum 225, 326 and 338 consoles fitted with factory Optocore, on a loop using ST connectors (or adapters). It has no MADI port, so it cannot connect to an S21 or S31 directly.
Takes the SD-Rack family I/O cards listed below. Matching DMI Optocore cards: MODDMIOPST (multimode) or MODDMIOPSTS (singlemode, needs the singlemode upgrade on the rack).
- Analogue: 32-bit Mic Pre (MODSDRADC32B), Mic/Line ADC (MODSDRADC), 32-bit DAC (MODSDRDAC32B), DAC (MODSDRDAC)
- AES: I/O BNC (MODSDRAESB), input (MODSDRAESI), I/O (MODSDRAESIO), output (MODSDRAESO), AES42 (MODSDRAES42)
- Digital: ADAT (MODSDRADAT), Dante (MODSDRDANTE), HD-SDI (MODSDREMDE)
- Blanking plate (MODSDRBLANK)

Forefront Tip
ST suits venues with installed multimode fibre between stage and FOH. A Nano with two MODSDRDAC32B cards is a neat 16 output amp room feed on a single fibre pair.
