Hi folks. first post here and i am so glad to have found this site. for you guys using the separate preamp and then power amp config (mcintosh, qsc, etc), do you send a stereo signal out of the preamp to the two channels of your power amp? or do you send the signal out of the mono out to one side of the power amp. I am trying to determine how jerry did it to drive the speakers in a similar fashion. thanks.
Since my cabinet is mono, I fed a mono signal from the preamp to my power amp and bridged it mono. That was when I was using a Trio with a Crown 402 power amp.
Now, I run a two channel AR Focus power section, and use one channel for the feed from my Egnater preamp, and the second channel I use for the wet output on my Real Tube Reverb. But I'm still running one output from the power amp to my mono cabinet.
I suppose, if you were using a 2X12 cabinet, you could feed each speaker from a separate channel of the power amp, but I'm not sure there's any benefit from that unless you want to run some of your delay or modulation effects in stereo. But then you'd want to mike both speakers through the PA, too.
