Axiom Home Page Forums General Discussion Technical Questions Multiple EP’s, daisy chain or…???

Yeah, Sat; the receiver/preamp has to have circuitry to send out two voltages instead of one(but of reverse polarity)and the amplifier has to have circuitry to "re-reverse" them. Both units have to have the balanced circuitry provisions. Yes, assuming that the amplifier does have lower gain on its balanced input, an unbalanced signal(without the double voltage)fed into it would result in a lower sound level.

OK thanks, I believe I'm on track now.

Finally got the 500’s dialed in. I don’t know why yet, but depending on which one I turn on first, the sub with the lead from the AVR will not fire unless I turn it off, then back on again. After I cycle this, it fires just fine. I also ended up adding a third sub to this room. I had an Outlaw LF1 which the 600 replaced in the great room, so I figured a third sub couldn’t hurt in this room.

Initial impressions are good. The two 500’s seam to fill the room a bit more evenly. I’m still trying to figure out exactly what it is I like better and find lacking. The 600 on its own seamed to rattle things that weren’t secured properly, like a door. The 500’s don’t do this. When I was running the single 600, I didn’t have anything to complain about, till now. I don’t know how to describe this, but in short, the LFE is just generally smoother. There was a ‘boomyness’ before that is not there now. I did not notice this before, but now I do. The addition of the Outlaw smoothed the LFE out even more. Before, with the single 600, my SPL meter would bounce between 6 and 8 DB (yes, C and slow response). The two 500’s mellowed this out to about 4 DB. With the Outlaw in the mix, I am only getting a 2 DB swing. Not sure what significance this is yet as I haven’t had time to watch / listen yet.

I also spent some time messing around with the center channel. I added the VP150 above the screen. I played around a bit by disconnecting the M22’s and listening to just the VP, then swapped to the VP. Sonically, neither one really jumped out at me as significantly different in sound. They both sound just dandy to me. I spent a couple hours with the Dave Mathews BR disk and DD HD. One thing that bothered me some with running the M22’s as a center was I always knew that vocals and center imaging was coming from below the screen. My eyes would tend to drift to them. When I tried the VP on its own, same thing happened, but this time up – obviously. With both the VP and the M22’s firing, all is golden. Even when I sit to one side of the room, the center or the other side, the center channel is right where it needs to be, on the screen. I like this arrangement. I’m going to keep it as is. I had thought that I’d end up ditching the M22’s for another VP 150, but I have absolutely no desire to do this.

I have some more playing to do, but for now, this room has never sounded better.



The Outlaw hiding.....

I still like that room. I'm glad the VP150 worked out for you. I only get the sense that the dialogue is coming from below the screen when I think about it. When I'm involved in what's playing it never really occurs to me. But I'd still like to experiment with another M22 above the screen at some point. I won't have the space for dual vertical centers in the above/below configuration when I move my system and get a projector, but I'm still kind of curious. I will be jealous of people with high enough ceilings to allow for a large projected image and centers above and below.

Did you say anything about trying a single M22 below the screen instead of keeping both? I can't remember if you mentioned experimenting with that.

Very good, Mike; enjoy.

I bet that room sounds awesome. Sometimes I wish my HT was not part of a bigger recroom. Maybe it is time for some re-construction to isolate my HT.

Randy, your room is already way too nice. Stop making me more jealous.
