worldwide Gunslinger Registered: 03/31/01 Posts: 129 Loc: las vegas, NV 89031	I have a preamp that has 3 pairs of outputs, two unbalanced and one balanced. Can I use one pair of pre-outs for a subwoofer while using another pair for an amplifier? I think I can and I don't see any reason why this wouldn't work. Any ideas?

However, remember that the one going to your separate (probably) amp will have information of a sub.

I'm not sure what you mean by "have information of a sub". Doesn't each output have the entire audio spectrum regardless of what it's plugged into? Thanks for the reply, Steve

nfaguys Desperado Registered: 04/09/05 Posts: 500 Loc: Maine	Steve: Using outlaw 990 all three are active @ same time. There might be a different volume level because of balanced vs. unbalanced. I don't know for sure as I've never used the balanced out for sub. As to "information to sub": The sub output's info is low frequency. Others not so.

worldwide Gunslinger Registered: 03/31/01 Posts: 129 Loc: las vegas, NV 89031	I'm not using a 990, just a regular old preamp with three pairs of outputs. But I understand what you are saying. If I did this I would run the balanced pre-outs to my amp and one pair of the single ended pre-outs to my sub using a Y connector on the pre-outs. I can't see any reason why this wouldn't work but I wanted to get a second opinion before I start buying the components for this system. The other option is to buy a preamp with a sub-out, but then I'm limited to only a few brands of preamps. I appreciate the help on this, thanks...Steve

nfaguys Desperado Registered: 04/09/05 Posts: 500 Loc: Maine	Steve: Make sure the sub has crossover on it. A 990 is the best bet. You can set crossovers for your center, mains, surrounds, and back surrounds. Outlaw has given us a greatly reduced price on 990s. As you can tell fromy my sig I think it's great I have one in each of two systems. _________________________ Living Room: 5.1 Surround and 4channel inline room 990/7700/6-KEF-107s/LFM1 x 2/ SMS Awaiting Trinnov Millenium dts decoder;Digital Director Players: Tascam CD01U/SonyCX455 x 3/DV955/BDP83 Old Sony 60" SXRD TV Zone 2 (also liv-Room: listening to music while Mrs watches TV): Crown SL2 preamp/D40 Amp/Stax Headphones My "Man-cave": 4 channel-only inline room.

worldwide Gunslinger Registered: 03/31/01 Posts: 129 Loc: las vegas, NV 89031	The sub would be an LFM-2 so it would have a crossover on it. This is for a bedroom system with two monitors and a sub. I already have a full blown HT with a 950/770/LFM1/B&W N804's. The 990 would work great for this system but it's more expensive than my budget allows and I really don't need all of it's capabilties.

gonk Desperado Registered: 03/21/01 Posts: 14054 Loc: Memphis, TN USA	Since it's a stereo pre-amp, make sure what those three pairs of outputs are. I'd guess that with one pair being balanced and the others unbalanced that the balanced and at least one pair of unbalanced are "pre-amp outputs" (thus always active and downstream of the pre-amp's volume control). I'd be a little worried that one might be a record output, though, in which case it might not be active all the time and would not be affected by the volume control - thus making it a bad candidate for connecting to the sub. That's the only concern that I'd have about this arrangement. _________________________ gonk HT Basics \| HDMI FAQ \| Pics \| Remote Files \| Art Show Reviews: Index \| 990 \| speakers \| BDP-93
