D2-926xx
Input audio may be received from the S/PDIF input for 2 audio
input channels, concurrent with and asynchronous from audio
that is also being presented to SAI inputs for other audio input
channels. Routing through the SRC synchronizes this audio from
multiple sources for synchronous audio processing within the
DAE audio processing paths.
SERIAL DIGITAL AUDIO OUTPUTS
Up to 4 SAI ports (up to 8 channels) are supported in the DAE-3
families.
• The DAE-3 supports 4 independent I²S output ports for a total
of 8 channels of audio.
• the DAE-3HT supports 1 I²S output port (2 channels) and that
port is configured to operate as either an input port or as an
output port.
Use and channel assignment to the SAI outputs is configured
using the Audio Canvas III software. Any of the DAE device’s 12
audio processing channels may be assigned to any of the
available SAI output channels. Audio Canvas III also assigns use
of the 4th SAI port as in input or output for the DAE-3HT.
