Wireless Headset Low-End Frequency Response

DSPedro
Prodigy 205 points

After doing some testing with the Wireless Headset Dev kit, I am pretty unhappy with the low end performance. For audio applications I would expect a 3dB point at 20 Hz, however all my testing has shown it is closer to 30 or 40 Hz. Any ideas for boosting the low end performance from the reference design? 

Thanks,

Pedro

    Hi Pedro, 

    You can customize the DAC inside the AIC3204 to fit the response you need. 
    Have a look in the datasheet for the AIC3204 for the registers to tweek and the PurePath Wireless Configurator Help system and "audio device definition files" for assistance on how to make the changes. 

    Hope this helps.
