ADAT Track Routing, ASIO at 96 kHz

This diagram shows the signal paths in ASIO double speed mode (88.2 / 96 kHz). The devices
available under ASIO have been implemented according to the hardware. Signal routing is
identical for record and playback.

Device: The device name in the audio application

SR: Sample Rate

Device name code: Channel in ASIO host, ADAT interface, DIGI9652, card number
