RE: Questions about high pass filter and balanced bridge
Posted by Blackdog on June 13, 2017 at 14:13:36:
You do need the input impedance of the amp. However just because you are bridging the amps doesn't mean the impedance is cut in half. There is probably a phase inversion circuit at the amps input that may need to be taken into account.
What amp are you using?
