Note:
The Internal and External Mixer are completely independent. The Internal Mixer controls
normal PC audio functions such as Windows sounds or CD Audio playback. It is represented by
the AC-97 Codec on the card. The External Mixer section is separately used by the audio
recording/mixing applications with support for up to 24bit/96kHz.
The Mic In, Line-In, Line-Out, Aux and CD-In are routed through the AC-97 Codec on the
AudioDSP24 and are controlled by the Internal Mixer.
S/PDIF I/O are connected to the XG DB I digital I/O board via the External Links function.
S/PDIF Master Clock rates are set in the Hardware Settings and can be synchronized via an
external S/PDIF source or internally on the Audio DSP 24. The default setting is 44.1kHz.
Up to 4 external ADC and DAC boxes can be routed through the Audio DSP24. The input and
outputs of these external boxes are connected to the External Mixer.
