Hooking up the Dayton 12" sub

[scott916]

A buddy of mine recently purchased an Onkyo TX-SR505 that has a mono line level subwoofer out. His Dayton 12" SUB-120 has a stereo line level in for the input. Should he just buy a mono to stereo adapter cable to hook up the sub properly?

Just hook up to one of the line level inputs (usually Left is suggested in manuals). No need to hook up with a y-adapter as the Left and Right inputs would be summed to mono by the sub anyway.

You should just be able to hook up to one of the inputs and it will work fine.

Edit: Bah. Yoyo beats me again

Cool, I figured as much. That's what he's doing right now. Thanks guys.

Receiver will say subwoofer pre-out
Sub will have low-level inputs labeled L and R

I see now, my BIC says LFE on the left input, I guess I can see, just put it in the L Input port.

I think I read somewhere that a few rare subs will have issues unless you plug in both inputs. That said, I doubt this is one of them.

Yeah, that seems to commonly come into play when the sub signal coming from the receiver is rather weak and some subs have problems detecting that and turning on when set to an auto-on setting. This can be avoided by turning up the gain on the subwoofer pre-out and turning down the gain on the actual subwoofer to compensate... but in some cases it seems like the y-splitter might still be necessary after changing those settings.
