Hello Kato San,
Almost all the TAS570x devices can be used in PBTL mode, but the paralleling of speaker connections must be done after the output filter. PWM Output Mux Register (0x25) should be configured to send either Channel 1 or Channel 2 to the tied outputs.

Hi Diego-san,
Thank you for your quick response.
I understood that TAS5707 can output either channel1 or channel2 as PBTL.
So, can it output the mixing output such as "(channel1 + channel2)/2" ?
Best Regards,
Kato
Hi Kato-San,
Unfortunately there is no way to mix Channel 1 and Channel 2 signals into PBTL mode with this device.

Hi Diego-san,
Thank you for your support.
I have an additional question.
Do you recommend to adder the audio analog output signals of the left channel and the right channel by connecting a speaker after the external LC filter if TAS5707 does not have the mixing function internally?
Best Regards,
Kato
Hi Kato-San,
This device can only route one channel to the output in PBTL mode, there is no way to mix the signals internally. The output from different channels should not be tied externally by any reason.
