Please help me not make a dumb mistake


I am putting together a new secondary system. Among other things, I am planning on hooking up a Rhythmik F12G subwoofer using the subwoofer's SPEAKER level inputs. On the Rhythmik website, its says:

"Our speaker level inputs are only compatible with power amplifiers having single ended outputs with black lead output labelled as "COM", "GND", or "Ground". Wyre4sound power amplifiers and others with differential outputs are not compatible."


The amplifier I would like to hookup to the subwoofer is a Prima Luna Dialogue 4. The Prima Luna's black lead outputs are not labelled "COM," "GND," or "Ground." They are labelled 0 Ohm. Is that the same thing as ground?

In other words, can I safely hook up the F12G subwoofer to the Dialogue 4 amp using the subwoofer's SPEAKER level inputs?

Thank you.

Your speaker level inputs share a ground common between left and right. Amplifiers that use differentially balanced circuits have separate grounds for left and right. I'm pretty sure the PL amplifier is a single-ended amp, so you should be fine, but it might be wise to check with your dealer or the manufacturer just to be sure.
