Yeah AFAIK dedicated sub outs tend to be the province of AV amps and that's not an area I have any knowledge of. 2 channel mostly (?) seem to just connect to any full range stereo out, using a Y connector if you only have one sub. Maybe to do something as simple as that on the back panel via a mono switch would be more elegant? REL's should preferably be connected to the speaker terminals on the back of the amp according to the manual and that's how I use mine.

Having tinkered with a sub solely for 2 channel music use, my feeling would be that a volume controlled output pair with a summing switch would be more than sufficient. |

I would concur with that. As almost all subs have their own filter arrangement and the object is to keep things simple, the volume controlled pair with sum switch should be more than adequate. Such an output might also prove useful for those wishing to bi-amp. It should also be borne in mind that many or even most(?) users will never use such a facility. |

Just listen, if it sounds good to you, enjoy it.

Elaborating a little, I am not suggesting a separate volume control, only that the signal pass through the same circuit as the stereo preamp stage but with a summing switch inserted immediately before them. So, parallel output but with the option to sum. Or, put another way, a preamp out with its own mono switch. Edited by tg - 18 Jul 2015 at 7:14am |

For me the simple "sub out" phono socket would be a full range signal L and R summed after the volume control. Let the sub do the LP filtering and no HPF (other than DC blocking) in the main L/R signal path.
As previously posted I use a pair of REL subs connected to the main speaker feeds (high level) blended into the speakers' roll off. I think the same approach is best for low level connection of a subwoofer for stereo hi-fi. Contrarily I'm fine with having bass management in multichannel AV. |

Would a pair of pre-outs and a pair of power-amp inputs at the back be a solution? For "2.0" listeners without subs the sockets would be linked together and for those few "2.1" listeners with subs a talented little GSP box of tricks could be purchased and placed inbetween the sockets. This would split out the lows and highs accordingly. The highs would obviously be fed back in and the lows would go to dedicated sub outputs. Saves 2.0 listeners from paying for possibly complex electronics they don't need?
btw - Will it have tone controls? :-p |
