Hallo
I am using the TAS5782 EVM board at the moment for a project. I was preforming some measurement today using Klippel system with the speaker connected to the TAS5782 EVM board in USB mode. I found an issue in between two measurements, I state the workflow below so it is easier to recreate the problem
The speaker is connected to the EVM board, EVM board connects to the PC via USB and audio is played from the PC. A microphone is used to measure the SPL data.
I was working with a project file in ppc3 GUI, then I changed to a different project file and changed back to my project file where I was working. Without changing anything I performed a measurement and I got a corrupted/different SPL response. See the attached picture for the difference between the original and corrupted SPL response. Then I simply turned off and on my power supply to the EVM board and measured again and now the SPL response was back to the original SPL response.
After doing some more measurements I found out that this issue is similar to using the invert phase of BQ1
in the crossover tab.
