Citation 7.1 CUTS out, do I need More Power?


I have a 7.1 which I am using in a bridged mode,
450 x 2 @8ohms and at a very loud, close to clipping probably, the amp will cut off, then back in, then off, then back in, and so on. When I turn the volume down,
it is fine. Is this some type of internal circuit to prevent damage to the amp/speaker?

Anyone?

Also, does this mean I will need more power for the volumes I am listening at?

Thanks,
Dan

WELL!! It isn't the amp! I used another amp, a Marantz MA-24, 30WPC Class "A" european release only, and it does the same thing at relatively the same level, volume. Does this mean the Aerial 10T's are halting the power from coming in to prevent blown drivers?

I wanted to thank each of you for your help. After several attempts with different amps, Citation 7.1, McIntosh MC-352, Marantz MA-24's, California Audio Labs CL-2500, and the Bryston 4B, (which all clipped) I have found the solution! No clipping, incredible clean mids and a top end that does just sing with a bottom end that DOES NOT STOP, the 4 channel Citation Audio 7.1 in a BIAMP configuration!
I had been bridging this amp which was probably a large part of the issue here. The amp is 210 x 4 into 4 ohms, and plays ever bit of it! The imaging is far superior, but not sure if it from NOT running it bridged or if it from the benefit of BIAMPING, but I FOUND IT!

Thanks so much for all of your help. I also have a call into the Aerial, Mike Kelly, to verify my hearing/sanity.
(really to be sure I won't blow the midrange and/or tweeter with this power.

Again, thanks for all your help and insight, it is threads like this that allow suggestions to be sought, issues recognized, and problems solved!

Wywhcan,

First, I would LOVE the factory power specs, please do send them!

As I mentioned, when I had this amp bridged, it stays in 8 ohms. After switching to BIAMP the speakers, the 7.1 runs 150 x 4 @8 ohms, and 210 x 4 @4ohms. This has made ALL the differences in the world. It was 11:30OPM last night when I made the switch and wasn't able to run very loud very long. The clipping/shut down happens ABOUT 100-112db. I am using the Radio Shack analog SPL meter and am just figuring out how to use it. The shut down happens around 100, give or take.

I don't sit around and listen to music (or Madonna for that matter) at these levels, but I am setting things up and like to push the limits, checking things like this at the same time.

I think running 4 channels of the 7.1 to the 10T's and 2 channels of the other 7.1 to the CC3B will be plenty of power, and good sonics as well. This leaves me 6 MORE channels (since I am using 3 7.1's) for surrounds, sides, and for the deck speakers.

Thanks for the input Wywhcan, and please do send me the specs!!

Hi Brian,

No, actually in just straight stereo. I am about to push the biamp configuration now and see what the outcome is.........
