Hi,

I'm using TAS5766MRMTEVM with PPCMB and PurePath Console 3.

Is there a way to use two different stereo signals (analog Inputs 1 and 2 of the PPCMB) and route them separate to

sterero out 1 and 2 of the TAS5766MRMTEVM?

Thanks for your help,

Marc

Hi Marc,
As far as I know, this is not feasible. Let us confirm this on the bench and update you later.

Hi Shawn,

thanks for having a look at my issue.
Any other way to run two stereo signals would also help me.

Best regards,
Marc

Hi Shawn,
I got quite the same issue here with USB-Output. I was also trying to route the USB audio signal to the four different outputs with no success.
I think that the main problem here is that the motherboard is recognized only as a 2-channel device by the computer.

PS: Could you also find out, what the jumpers AOUT1, 2, 3 and 4 do if i short them?

Thanks in advance,
Felix

Hi Marc,

As shawn explained, it is not feasible. Two TAS5766M on the EVM share the same I2S.
Please refer to UG of TAS5766MRMTEVM: www.ti.com/.../slou387.pdf for more details.

At present, I am sorry that existing hareware (EVM + mother board) cannot satisfy you requirements.

Regards,
Alix Wan.

Hi Alix,

one last question...

I tought about a simple workaround for routing 4 channels. I simply plan to use two PPCMB's each combined with an TAS5766MRMTEVM.

Is it possible to flash my tuning to the TAS5766MRMTEVM's and keep it flashed despite disconnecting USB and power connection.

If this is not feasible, can I run two PPCMB's on the same computer?

Thanks for your help.

Regards

Marc

Hi Marc,
Unfortunately PPC doesn't support running two PPCMB on the same computer. I think you need two computers to verify 4 channels application.
