Probably a stupid question but.... (bridging O/P on stereo power amp)

Funny how long you can go without checking your assumptions. I'm running a stereo Ric into two separate mono preamps. then into a stereo power amp and then into two separate cabs. Now I've always assumed that if I was only running the power amp into one cab, I could only run one preamp into the bridged/mono O/P. It's just occurred to me however that my assumption might be wrong.

So, which of the following is the case?

1. You can never run two preamps into a power amp in bridged mode?
2. You can run two preamps into a power amp in bridged mode if the manufacturer lets you (i.e, it's designed to be run this way)?or
3. You can always run two preamps into a power amp in bridged mode?

Thanks

Chris

Not in my opinion no.
In bridged mode, you use one side of the stereo amp for the positive side of the balanced signal and the other side for the negative side.
Have a read of this for the signal chain [url="http://www.dbxpro.com/forum/viewtopic.php?f=60&t=2136"]http://www.dbxpro.com/forum/viewtopic.php?f=60&t=2136[/url]
If you want to retain your two pres just use a 2 into 1 input mixer.
