MOTU 2408MKIII-EXP-I/O

A core 2408mk3 system provides 24 inputs and outputs, but it also offers the most expansion ever offered in a single PCI card. Up to four interfaces can be connected to the PCI-424 for up to 96 channels of simultaneous input and output at sample rates up to 96kHz.

Think about the possibilities: you could connect 12 ADATs and 12 DA-88s to your computer, along with 32 channels of analog I/O, and simultaneously record and play as many tracks of audio as your computer allows. If you have a digital mixer, the 2408mk3 provides up to 96 channels of digital I/O at 44.1 or 48kHz, and 48 channels at 88.2 or 96kHz.
