Hi all,

I have a Crown DC-300A II and I want to measure the signal to noise ratio.

A 20Hz to 20kHz low noise bandpass filter needed for this measurement and the service manual says "information available at Crown" but the actual support don't help me.
(product is too old !)

You have an idea to build this filter ?

Thank you,
Jose
