I have designed a TDA7575B based audio amplifier, see attached screenshot image. The tone control as configured, will the input signal not be below standard 2v line input voltage that the TDA would typically be used with? I dont know how to add a preamp. Can someone please clarify or help me to get it designed. I apologies and I am new to electronics.

Making a million topics on the same issue just pollutes the forum...
Anyway. Even if that is not strictly required, this version with negative inputs connected to GND through a separate C11 and C18 is 100% safe and will definitely work.

Hi, @IHus.1​,
You had also posted this and the former question on Stackexchange.
Can this question here be taken as answered?
Regards

Yes sir I got it done and now waiting for the fabricated PCBs. Stachexchage is a great platform. Thank you very much!
