ADAU1442 channel assignment

Hi Christian,

Once you are inside the DSP core (where you can program and control the signal flow and processing via SigmaStudio), you are free to route signals as you choose, in mono or stereo, mixing or splitting signals as you wish. The only place where the signals must be routed together as stereo are in the following places:

The serial ports

The routing matrix

The ASRCs

If you have any more questions about this, let me know. It might be helpful to see a simple diagram of what you're trying to accomplish.

Hi Brett,

that's comfortable.

A further question: when i have already occupied 24 channels (by using of SDATA INs and SDATA Outs) and in addition i want to use the SPDIF IN and SPDIF OUT (in this case monaural as channel number 25, ), is this practicable (at the back of my mind the DSP is normally defined for 24 channels only) ?

Kind regards

Christian

That's possible. Technically, the DSP has 42 inputs:

The 24 serial audio channels, 16 inputs from the ASRCs, and 2 S/PDIF inputs.

There are also 42 outputs: 24 serial audio channels, 16 outputs to the ASRCs, and 2 S/PDIF outputs.

Note that most of the time, S/PDIF inputs are asynchronous, so you'll want to run them through the ASRCs.

That's nice.

Many thanks

Christian
