Allen & Heath dLive RackUltra FX Card
The RackUltra FX Card combines Allen & Heath's FPGA processing with an onboard ARM chip to open a dLive system up to another generation of onboard effects. It installs into the internal expansion slot on any existing dLive DM or CDM MixRack, and ships fitted as standard on new MixRacks, without borrowing from the platform's existing busses, channels, RackExtra FX slots, or Audio Networking I/O ports.
The card adds 8 RackUltra FX engines that run as sends or inserts alongside the console's existing 16 RackExtra FX units, each with its own dedicated stereo send and return so they don't eat into a standard mix bus configuration. Every FX engine also carries built-in 4-band PEQ and dynamics, compression, gating, expansion and ducking, with sidechain, on both its input and output.
