TAS5766M: Mono Operation to 2.8KHz

John Garrett
Expert 4220 points
Part Number: TAS5766M


Hi All,

 

The Pure Path 3 development kit software limits mono operation to 1kHz & below.  My customer typically uses the register dump from the EVM & have it programmed into their firmware.  The project they are working on is a single point stereo configuration, where the woofer hands off to two tweeters at ~2.8kHz.  They want to run mono up to 2.8kHz, is there a work around for this?  In other words, can they just edit the dumped register setting for this parameter & if so where would do they find it?

 

Thanks & regards, John Garrett TI-AFA

    HI John,

    May you give more information about the test setup and condition?  what is the audio source frequency? the output frequency depends on audio source frequency.

    Hi Garrett,

    Could you specify more details of current issue? it's not quite clear.

    How many TAS5766 in the system? (maybe 2 devices, one for PBTL mono Woofer, one for BTL stereo Tweeter, is it correct?)

    What's the meaning of 1kHz / 2.8kHz limitation? Is it the frequency response curve? If so, please share us your ppc3 configuration file.

    Regards,

    Matthew
