I don't think there is a independent Standby for each channel, so if I want to use only Ch. 1, do I need to still have a load on Ch. 2 as well even if it's not in use? Do I just put the volume all the way down? Couldn't find anything in the manual, but I know for a Mesa 20/20 I used to own you just put the volume down on ch. 2 and the presence all the way up on the 2nd channel or something? Same for this power amp?

I guess someone here may know the answer, or maybe jeff or bruce can chime in since I believe bruce designed this power amp?

I do.
 
not sure about that really. I know it has a mono/stereo switch on teh back, not sure if that allows the need for only a load on the used channel.... ? hmmm

Yeah theres a mono/stereo on the back, At the moment I have it set to Mono, with the volume on ch. 2 down, just want to confirm that I'm not hurting the power amp doing it this way.

Also one more question, with the mono, if I feed just input 1 does the signal go to both channels? Same for Stereo? Any help is much appreciated :rock:
 
You only need one cabinet if the Switching/Stereo switch is set to Switching. Then just plug your cab in the CH1 outputs.
 
You don't need a load on channel 2 if you set it up for switching mode. . It's a switching power amp and it detects if nothing is plugged into the speaker jacks on a channel. So if you have a speaker cab in channel 1 and the switch set to "switching", you don't need any other speaker load on channel 2. I do this to get the benefit of switching the channel/tubes into one cabinet.
I confirmed this with Randall FWIW.
