Stereo sub out to mono, is it safe?

I also do not agree to the "use one side" theory. I have quite a few recordings where the bass may be on one side or the other or even switching from right to left etc. This is on a 2 channel system of course.
When I asked Krell if I could do it VIA a "Y" connector they said go ahead. I never ended up doing it though for the same reason I note above.
Good luck, JD

I would check with the factory. I haven't a clue, but if you check my threads, you will see that I had a custom summing buffer made to mix the channels into mono for my single sub woofer. If you learn that you also need the type of device I have, give Tom Tutay a call. I believe his number is listed in one of my threads.

Phasecorrect, I'm not sure whose answer(s) you are referring to as "bizarre," but the original question was not which channels bass "can operate in," or whether a sub "acknowledges left or right." The question was would it be safe (or could it cause damage or other problems) to combine the left and right channel sub outputs of an integrated amplifier by shorting them together with a y-adapter.

Geared4me, the suggestion by Bifwynne is an excellent one. A line-level mixer having reasonably high input impedance, and that provides RCA connectors, would eliminate all of the possible issues that have been discussed.

Well...in thirty years of audio I have never had an issue combining channels to form mono from a pre out...adding a mixer seems complicated and unneeded...as does utilizing only one pre out channel...just my findings...
