I need help hooking up a unique speaker setup. Right now the problem I am having is that I am getting popping sounds from the speakers every now and then, humming/buzzing, and really horrible sound quality. I am going to begin by telling you the equipment I am using and how I have it hooked up currently and then ask you guys what you thing I should do.
the equipment i am using is:
4 - JBL 15Inch 2-Way Speaker Passive Full Range Speaker (they are stacked 2 on the left two on the right)
1 - EUROLIVE B1800D-PRO High-Performance Active 1400-Watt 18" PA Subwoofer With Built-In Stereo Crossover
2 -Alto Professional TS112A Truesonic Powered Speaker - (these are the booth monitors)
1 - 400 watt mixeer
1 - QSC PLX1104 Lightweight Power Amplifier
1 - pioneer ddj-s1
Okay so this is how I have it hooked up right now:
ddj-s1 conected to the B1800D-PRO sub inputs via xlr
B1800D-PRO sub outputs go into the 400 watt mixers inputs 1 and 2 via xlr
400 watt mixers powered outputs go to the 2 left and right jbl speakers via 12 gauge speaker cable
400 watt mixers stereo outputs connect to QSC amp input via 1/4" to xlr
QSC amp out puts go to remaining 2 left and right jbl speakers via 12 gauge speaker cable
1 JBL speaker output to Alto powered speaker input via 1/4" to 1/4" -----"daisy chained"
Alto powered speaker to other Alto powerd speaker via 1/4" to 1/4" -----"daisy chained"
also these alto speakers have a ground and a contour button on them that i have no idea what they are for however even the two Alto speakers are not on the setup I have still having sound issues.
Now that you know how I have it hooked up let me tell you this:
The sound issues that I am having mainly occur when I have the sub hooked up. If I bypass the sub and connect the DDJ-S1 directly to the mixer the popping and humming in the speaker is less likely to occur however it still does occur. I have done research on the DDJ-S1 and it seams to be a ground loop issue or something but is there another way I should hook this up like all the powered stuff 1st or all of the powered stuff last.
What would you do or what should I do?
