The SD-Rack is configured in a 56 input / 56 output arrangement, in blocks of eight, allowing you to populate the SD Rack with the I/O cards to suit your application.

These include analogue inputs and outputs, AES inputs and outputs, bidirectional AES input / output, AES-42, ADAT and Aviom. The cards themselves are hot-swappable, with the SD Rack automatically detecting the card that has been plugged in, and further I/O card options are already in the pipeline for future development.

The provision of built-in Gain Tracking 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 SD console, covering a signal level range of +/-40dB. Splitting is also provided on the SD Rack’s analogue and digital outputs, allowing you to split the input signals directly out to, for example, an analogue or digital monitor console. Splitting and sample rate conversion is even offered on the two dedicated MADI SPLIT outputs.
