Members troyri Posted July 6, 2011 Members Share Posted July 6, 2011 Is there any advantage to using the low sum output apposed to the left and right output? Or is it just one less cord? I assume most run their subs in mono but not sure. Link to comment Share on other sites More sharing options...

Members twostone Posted July 6, 2011 Members Share Posted July 6, 2011 I run my whole PA mono. Had a DBX 223 x-over go bad on me at a gig and lost the low sum out so I just swapped sides on the x-over and was back in biz again. Link to comment Share on other sites More sharing options...
Members Unalaska Posted July 6, 2011 Members Share Posted July 6, 2011 I almost always run stereo triamp or biamp. In reality it's dual mono since not much of anything is panned. I like the redundancy and if there is an issue then just use 1/2 of the amp channels and fix it after the gig (this has happened maybe 2x in 5yrs).

Members troyri Posted July 11, 2011 Author Members Share Posted July 11, 2011 So another dumb question I'm sure. If I do decide to use the sum out on it and the PV doesn't have a parallel setting, can I just run out of the 1/4" out on channel A to the 1/4" input of channel B? I think the answer is yes but I'd really rather the experts tell me for sure. Link to comment Share on other sites More sharing options...

Members boomerweps Posted July 12, 2011 Members Share Posted July 12, 2011 There are advantages and disavantages with both method. Using the mono-summed sub output, you get the mono out AND can underlap the crossover point if desired, but it does require adjusting 3 frequency points and trying to get them to match.Using the low out for subs, in stereo OR just using one side's low out, means the point of high to low frequency crossover point IS matched.With analog crossovers, you don't know how close the low and high cut points will be, adjusting the rotary knob indicator with the silkscreened frequency marks. Normally I just used the high/low out for tops and subs and ignored the mono summed sub out. Boomerweps Link to comment Share on other sites More sharing options...
Members troyri Posted July 12, 2011 Author Members Share Posted July 12, 2011 Roadranger, just curious for my own knowledge. Why do I have to use TRS instead of TS? Link to comment Share on other sites More sharing options...
Members RoadRanger Posted July 12, 2011 Members Share Posted July 12, 2011 Roadranger, just curious for my own knowledge. Why do I have to use TRS instead of TS?because the inputs are balanced and a TS cable will short out one side of your XLR input . Link to comment Share on other sites More sharing options...
