Crown MA12000i input HPF

[muriloalvares]

Hello, any Crown amplifier expert here? I would like to know if it would be possible (I mean, something easy to do) to change my MA12000i input HPF, say by changing the series capacitor?

We would really need to see the circuit details to advise. The obvious question is why you feel it needs altering.
