shockers Posted July 5, 2005 Posted July 5, 2005 Just reading a couple of old posts and think I may have found an answer to a forgotten problem/situation, but wondered what your thoughts were!I run peavey hiysis 2 and peavey low riders (an 18" specialized, [according to Peavey], driver), all driven by 2 Yamaha amps via a dbx controller. I don't think that the decibel level for the kit I have seems to be right. (ie not loud enough), Its only when reading someones comments on XLR's and there correct wiring, that the little light upstairs went on! :unsure: In the passage of time I have accrued various leads, as you do!, but have never thought about whether they are all wired in the same 'pin hot ' sequence. Would this make any difference? If so small or big? Just thought I'd ask before I go and take everything apart.
Just Some Bloke Posted July 5, 2005 Posted July 5, 2005 If you're talking about speaker leads, then wiring them opposite ways would result in them being in opposite phases. If you pointed the two speakers directly towards each other then the level would be drastically reduced as the phases cancelled each other out. Assuming you're pointing them both at the audience, then it shouldn't cause too much trouble, though it would be a good idea to make sure that whatever pin connection you use at one end, you use the same at the other end - this will ensure you're not swapping phases. I'll let others comment in the other leads in the system but, personally, I can't see a problem there myself at first thought.
ChrisD Posted July 5, 2005 Posted July 5, 2005 don't mean to be patronising but has the OP actually tried theses speakers under test conditions with an accurate dB meter and the correct signal etc?
Simon Lewis Posted July 5, 2005 Posted July 5, 2005 If you pointed the two speakers directly towards each other then the level would be drastically reduced as the phases cancelled each other out. You would certainly observe a loss of lower frequencies, and some broadband loss, but as the two sources are not coherent, perfect cancellation does not occur. The scenario described is one of polarity reversal, and has little to do with phase.
