stevensannes72 Posted July 25, 2013 Share Posted July 25, 2013 So I have my HD500 running mono into a Mosvalve MV-962 power amp and into my Carvin 4x12, it sounds good but when I try to run dual amps (Treadplate and Angel F-ball) and pan them center it sounds like the signal is overloading and fuzzing out. I have my input set to guitar and same. I noticed this when running stereo into my monitors too, as soon as I start panning them to center from far wide left and right it starts fuzzing out.

phil_m Posted July 25, 2013 Share Posted July 25, 2013 Well, it could be phasing or comb filtering occurring - that's possible. Not every stereo sound you sum to mono will sound right. Any chance you could put up a clip? Quote Link to comment Share on other sites More sharing options...
stevensannes72 Posted July 25, 2013 Author Share Posted July 25, 2013 I don't have a way to post a clip right now. So everyone that uses dual amps keeps them panned hard left and right? I noticed when running in stereo through my monitors dual amps panned hard left and right sound good but very separated and as soon as I start panning them toward center it starts to get that overloaded fuzzed out sound. I was hoping to blend both amps in my mono live setup. Quote Link to comment Share on other sites More sharing options...
Inerzia Posted July 25, 2013 Share Posted July 25, 2013 It's what phil said, phase problems. Try different combinations, after all, those two amps you mention aren't that different from one another.I have lots of dual path patches because I usually run both channels to PA, but for different gigs where I can't run in stereo, I have a different setlist with mono-able patches Quote Link to comment Share on other sites More sharing options...
stevensannes72 Posted July 25, 2013 Author Share Posted July 25, 2013 When you run mono do you pan both amps or keep them in the center? Quote Link to comment Share on other sites More sharing options...
Inerzia Posted July 26, 2013 Share Posted July 26, 2013 In mono I just use one amp, but there are some combinations of amps that can sound OK together when panned to the center, depending on what you're looking for. I've "found" that layering different sounding amps with very different settings (i.e. one clean, one dirty) produces less phase problems.If it's metal tones you seek (or any high gain kind of tone for that matter) and you are running mono, better use just one amp. You can try different combinations of amps, if you have time to spare, but if you don't, choose one amp and cab that you like and work with it.Now that is something that can be improved. If the cabs were phase-aligned, we wouldn't have these problems Quote Link to comment Share on other sites More sharing options...
spaceatl Posted July 26, 2013 Share Posted July 26, 2013 You post made me think that I do it a completely different way...Thought I would share...blending amps does not have to be summed...Although that is simple to do, the phasing can be a nightmare as folks have already pointed out...You can run amp models in series...run a PRE (no cab) into a FULL model (cab & mic) for a direct tone...PRE into PRE...(no cab, no mic into real guitar power amp and cab)...place the FX so the PREs are where you want in the chain...It looks a little skewy but I quite like it and gives a little more control on a mono rig much like I would with real gear...one preamp into another? sure, that makes sense to me...That's exactly what a Mesa Boogie Mark I is... you can chain dual amps in series...just using a PRE as an EQ is nice for shaping and give some neat character...using one as a boost is pretty cool...Anyway, I have done this with my HD Desktop...A bit of a pain with that since there is no FX loop and an adapter is needed. Cake on a 500... On the Desktop I run left output back to the Mic input (adapted) and turn the trim all the way down...setup the input as guitar and second input as mic...mixer A hard left; mixer B hard right...right output goes to power amp in on guitar amp...I prefer my SVs for this setup as the master works unlike the DTs...getting it just right is challenging since the analog master L and R are coupled...Dual analog masters would be so cool...concentric pot would be cool...but it can be worked around... On a 500 this is cake as no adapter is needed...run left out to aux in and setup the inputs and mixer accordingly...you could use the FX loop on a 500 to serialize and have better control on the out to aux level so it remains fixed and the master volume works as expected...Desktop needs external master volume as there is simply less control on that device... I have been hoping for a tad more DSP so I could run this way and really considering an X unit...really need a tad bit more for patches I use...
