Members SuperStrat Posted April 12, 2005 Members Posted April 12, 2005 I noticed, as I was setting up my newly aquired G-Major, that there is some phase cancellation on some of the effects. I
Members UncleDig Posted April 13, 2005 Members Posted April 13, 2005 I don't know the DSL's tech specs... is this a parallel fx loop? I use a G-Major in a parallel fx loop, and run it 100% wet (turn Dry Kill: On on the G-Major). I don't have phase problems. I have, however, heard them before - when I experimented with Dry Kill: Off, and created patches that had some of my original dry signal mixed in. In a parallel fx loop, that creates phase problems. If that's not what's happening to you, then ignore me As a side question - where can I find the true and final facts re: how to properly use the G-Maj in mono? The manual just seems to say "left in, left out" is mono, but I have read things (like your post!) that seem to indicate that there's more to it than that. Over time, I've seen conflicting things (some of them very complicated) re: what will come out of the l/r outputs depending on what is fed to the inputs. Can anyone fill me in? Dig

Dig Thanks for the input, I'll try the Dry Kill to see if that's the answer. Last night I used a mackie mixer to sum the left and right outputs from the G-Major and sent them as a mono signal to my amp -- serial loop, BTW -- the phase dropout disappeared. ART makes a cheap mixer, I think I'll pick one up and hide it in my rack.
Members SuperStrat Posted April 13, 2005 Author Members Posted April 13, 2005 Follow up: Here are a couple links that describe a very cheap way to do this... it'll work well for the G-Major because there is more than enough gain available to make up the 6db loss. http://www.tkk.fi/Misc/Electronics/circuits/linesum.html http://archive.avsforum.com/avs-vb/history/topic/412031-1.html
Members UncleDig Posted April 15, 2005 Members Posted April 15, 2005 You only want to use Dry Kill with a parallel fx loop. I see that in SS's response he says the loop is series. Dry Kill = On will sound horrible in this situation (cause the dry signal is being... well... killed) Dig
Members SuperStrat Posted April 15, 2005 Author Members Posted April 15, 2005 Originally posted by pretaanluxis Did the Dry Kill work? I didn't try it because my loop is serial. I did build the combiner circuit as described on the Rane site, it works great... problem solved and only cost $8.
Members pretaanluxis Posted April 16, 2005 Members Posted April 16, 2005 I'm surprised it doesn't have a setting that fixes that problem, sounds like it would happen to many people... I was thinking of getting a G-Major but since I can't use a solder for sh*t I don't think I will
