TAS5825M: Does TAS5825 Mix Stereo Input to Mono Output in PBTL Output Mode

Wayne Chen (Audio AE)

Part Number: TAS5825M

Hi Sirs,

As title, does the TAS5825M mix left and right input to (L+R)/2 mono output automatically if we assert 0x02 bit2 (DAMP_PBTL) to 1b?

Thank you and Best regards,

hello Wayne,

In addition to assert the 0x02 register.

It also need to configure the input mixer register in DSP:

w 98 00 00
w 98 7f 8c
w 98 00 0b
w 98 14 00 40 00 00 # Left to Left input mixer
w 98 18 00 40 00 00 # Right to Left input mixer

regards
Linda

Hello Linda,

Thanks for your advise. We will collaborate with customer to add these instruction to the EC code:

w 98 00 00
w 98 7f 8c
w 98 00 0b
w 98 14 00
> 40
> 00
> 00
w 98 18 00
> 40
> 00
> 00

Thanks a lot,
