The AKD8D Optional Card allows you to customize your Horus or Hapi interface for any Analog to Digital application.
Separate input and output cards allow you to customize your Horus or HAPI interface to exactly what you need for each application. Choose from standard, 192kHz (AKD8D) capable or extended use DXD/DSD (AKD8DP) capable Inputs and outputs to make sure you capture every sound with the greatest accuracy. Whichever you choose, be secure in knowning that you are using some of the best AD and DA circuitry in the world.
AKD8D Module
These remotely controlled Mic/Line Input cards have set a new benchmark in analog circuitry design, and provide additionally a Line level post Mic-pre "Direct Out" output.
