What are the card cages on the rear of the console and how do I use them?
The D8B card cages are a perfect example of the “open architecture” format of Mackie Digital Systems products. You can customize your D8B for specific applications by providing the appropriate cards for the card cages that give you the routing formats and effects processing you need. The Tape I/O card slots are for routing signals to your tape (or hard disk recorders) and returning those signals back into the console. Any of the Mackie Digital Systems Tape I/O cards can be installed into these slots. The ALT I/O card slot provides eight I/O capabilities in addition to the three Tape I/O card slots. The Effects card slots are used for internal parallel effects processing. Either the MFX or UFX card can be installed in these slots. The Sync card slot is for the D8B’s clocking mechanism. A standard sync card is installed in this slot at the time of purchase, but you can install the Clock I/O card in this slot.
