I'm about to buy a 1050 so I'm working out the interconnection details. My left, right and sub are all self-powered studio monitors (Quested) so I'll be using the 1050's preamp outputs to feed their inputs. I would also like to drive a second set of speakers, out on the patio, using the 1050's left and right speaker outputs.

Here's the question: When I connect to the preamp outputs will I break the normal internal connection to the 1050's power amp, or will the signal continue to flow to the power amp? I can make it work either way, but it would be most convenient to use the L/R preamp and speaker outputs simultaneously.

Thanks, in advance, for your advice. I look forward to joining your band of banditos very soon.

I think the internal amps still work when the pre-amp outputs are connected. My 1050 will reportedly be returning on Monday, so if you don't get a more definite answer before then I will hook it up and find out.

Gonk,

Thanks for your speedy reply. Have you had a chance to check this out? Anyone else?

I had hoped to get my 1050 back yesterday, but just got it this morning. It's sitting on my desk here at work. I should be able to do a quick experiment some time today or tonight.

Yes, the power amps still function even when the pre-outs are connected. I confirmed this a week ago when I borrowed a 750 amp and was doing A/B comparisons by switching the speaker wires between the 1050 and 750. I left the 750 connected to the 1050 and the 1050's amps still worked.

Kevin,

Thanks a lot for confirming this. Now all I'll need is an in-line attenutator (Niles?) and I'll be all set.

Uh, I believe I meant an "attenuator". Still a bit early here in L.A.

This answers a Q from me too. I'm considering using the 1050 for amping the top of Studio40's and CC and letting a Parasound855 push the bottom. The Paradigm Studio40's have a biwire imput(remove a clip) They still pass through a crossover, so my only problem would be dialing in a balance between the 1050 & the 855(which has a pot on each channel).
Any opinions welcome. Just looking for a cheap way to bi amp.

Forgot to mention- if the top is too hot from the 1050, I probably can't dial it down, since the amp outs are from the pre section and the 855 would `Turn down' as well.
I think?

Any Thoughts ?

Hey Eric. I have the exact same components as you do. Have you had any luck with the bi-amping? How does it sound? I just have one wire running from the 855 to each speaker right now. Bi-wiring hasn't made much difference with my system, but I am definitely interested in trying bi-amping.

You could balance with a sound meter... leave the clip in place, connect the output from one amp, and measure the level. Then connect the other amp and adjust the level so that it is even. Then remove the clip and connect both amps.

Since the volume control affects both the preamp and amp outputs, I think this would work.

Well guys- haven't bi amped yet, but the tricky business of pushing the tweeters to hard still bothers me. The best way would be to use 2- 5ch amps, but that's too much money.
The more I read, I get the impression that just adding more power would be best.

Hello,
I'm currently running two four-channel amps (HK PA 2000's) and one Carver amp. The easiest way to bi-amp is to use two channels with a common input per speaker. One two-channel amp per speaker, or go multi-channel. If you use matched amps, let the crossovers in the speakers do their job, and calibrate overall with an SPL meter, then you will have excellent results. The end result is well worth the money (IMHO).

Well guys, looks like my pre outs are screwed up. I had problems with the amp overloading and accused my seller of sending me a bum amp, but today I tested the amp with a funky old pro logic reciever that has 2 pre outs and it worked fine. I tryed the 2 channels across all the amp channels and it's OK.
I never used the pres before, so it looks like I'll have to pay to get it fixed cause I'm well past the warranty period. At least that's what I think-I'll find out Monday when I can get the Outlaw guys on the phone.

Bummer
Eric
