I have two technics 1200 and a pioneer DJM-600 i have the master volume on like 1.5 and the master knobs above each channel turned up about a quarter and the equlizer knobs turned up about about 2/3.
So when i turn up the master volume fader a really loud hum deep bass sound comes out. It vibrates the whole table.
Also the ground wires are messed up. Sometimes the sound will go out or lower in volume in one speaker. So i wiggle the ground wires and it will come back on.
How do i fix this its driving me crazy. any help would be appreciated.
It's not your ground wire with the issue, but your RCA cables. Try disconnecting both turntables, and connect 1 at a time, and do the same test, this way you can isolate the problem. Once you've isolated the problem, then you'll need to have the RCA cables replaced on your turntable.
You might also want to check the Cartridges as well. Sometimes a bad cartridge or headshell connection will cause this issue. Worst case scenario, its your tonearm, but that should be test last.
Also, on the rear of your mixer, there is a gain volume pot, make sure this is not maxed out. Keep it about 3/4 of they up. Again, this is on the rear of your mixer where you connect everything.
