London (September 13, 2010)--DiGiCo has introduced the SD Rack, an I/O rack that offers multiple format sample rate conversion and allows up to 448 I/O, in any combination at 96kHz, spread across multiple racks.

While the SD Rack converters can operate at 192kHz, users can also select other sample rate options for specific outputs--for example, MADI at 48kHz for broadcast or recording feeds, or 96kHz—so that the SD Rack serves as a multi-sample rate signal splitter. This can allow use of DiGiCo’s microphone preamps to replace the standard microphone preamps of an analogue or other brand of digital console. At 96kHz, the measured delay from the stage rack A-D, through a full channel with processing via the bussing with processing, back to the stage rack D-A is around 1mS.

Also integrated with the MADI split is Gain Tracking, which allows another console or a broadcaster to take any of an SD Rack’s AES, analogue or MADI outputs at a stable level, irrespective of the microphone preamp settings on the SD7, covering a signal level range of +/-40dB. This can be turned on at any time, so the one pre amp for each physical input can have four independently controlled levels.

The SD Rack has a 56 input / 56 output arrangement, in blocks of eight, and can accommodate multiple digital formats, including analog mic line inputs and outputs; MADI; AES inputs and outputs, both with sample rate conversion; AES I/O card; Aviom second generation module; ADAT module, providing eight ins and outs; and AES 42 module.

All card formats are independently hot-swappable and auto-detecting using Micro Blaze technology. The Mic card user feedback is provided by multiple LEDs and any input can be split internally to any opposing output on the rack. Power supplies are also hot-swappable, with all main connections at the top of the rack. Also, there is a full RGB backlit display that can also be used to control and program the unit.
