Title: Why the 220 ohm resistor between the two outputs?
Post by: ccmccull on December 07, 2021, 07:56:06 PM

I'm curious about the purpose of that 220 ohm resistor between the center pins of the two rca outputs. Does it cause the two outputs to behave differently at all? Thanks!

The resistors provide some isolation between the outputs, which can be helpful under certain conditions.  If you have long cables to a subwoofer amp, I would plug those into the second set of outputs.  The resistors will slightly increase the output impedance of that pair of jacks, but not substantially.

Thanks Paul! By chance I had my s/w & main amp hooked up in the opposite way. So I switched them yesterday to see if it made any discernible difference. The system sounds the same, or in other words, still amazing! Thanks again for the quick reply!
