Power amp question

#22
[Invalid or Expired Link Removed]

Read the specs, 2ohm per side stereo, 4ohm bridged. Peavey IPR's can be bridged but you need to jumper the channels and level match. Search the forum, a Peavey engineer posts on here and has explained how.

The QSC PLX 1104, 1804, GX3 & GX5 (not sure about the GX7) don't do bridge mono but you can run a single input and dual output using a 1/4" jumper. The amp will then run in stereo powering both cabs. I do this with my GX5 and get 500 watts into each of my 8 ohm Avatar 2 X 10 Delta cabs. It works great and it's fairly inexpensive.

So you don't actually have to have an amp that will do bridge mono to get a lot of watts / headroom.

But boy does the Carvin look great on paper. ;)

The 600w per channel at 8ohms is very appealing.

But I'm a bit skeptical when it comes to quality though.

I have used Carvin power amps in the past with no problems, also QSC has been problem free for me.

No, it means that the amp is running at 8ohms per side.
In your mind, treat each channel of the amp as a completely independent amplifier. Until you bridge, that's exactly what they are. All they share is a chassis and a power supply.

Even the QSC specifically says that is does not need bridged mode:

The PLX models ending in 04 will not bridge to 4 ohms, but all of the models ending in 02 will. The numerical suffix reflects the lowest allowable stereo impedance. For instance; Stereo 2 ohms is equal to bridged 4 ohms.

Regarding the Crown models, I was in fact referring to the XLS Drivecore series, which most definitely is listed on their website as Charlie kindly pointed out.

EDIT: A better question to ask is; Why do you think you need bridged mono operation? What is the displacement limited power handling of the cab(s) you're going to be powering? Do you understand the relationship of power and volume? Do you understand voltage swing?

No I do not understand the details behind all that. What I was thinking is when I only need one cab (8 ohm), I can get enough power from either one channel or bridged. Then if I want to add another cab, I can either go bridged at 4 ohms or use 8 ohms each channel and set each channel's sound a little different via 2 channel preamp (i.e. one clean, one with a little grit). I like having all the options. :) So far, the Carvin looks like it has everything, while delivering enough power for all applications.
