This applies to most Mac Amps, but mine will be MC611 mono amps. It has three sets of post per channel – 2, 4 and 8 Ohms.
My Speakers are PMC Fact 12. It also has 3 sets of posts LF, MF. And HF.
I would like to connect 3 sets of speaker cables. But I do not know which one should go to LF, MF and HF.
Or this kind of set up is not recommended.
