Hi Team,

A customer has a query on the DC cut caps 47uF for HPL&HPR.

Now he wanna use 16ohm HEADPHONE in 200KHz frequency.

can he cancel the DC cut caps 47uF in the circuit.

can he increase the caps value to expand the bandwidth? for example, 500uF.

But the caps size it too big.

Thanks a lot.

Hi Frank,

I am not sure I understand the question. I think the customer can use 500uF capacitors but will have to keep in mind the high pass filter created by the capacitors and the headphone load.
