Help me! I'm puzzled

I have done a detailed attachment to help y'all understand my problem. but then realised that its too big.my problem is written underneath, but if you e-mail me i can send you my drawings as well.


My problem


1. When I put a record on turntable 1, with the crossfader to the left (ch.1) and play the Record, everything is fine. When I put a record on turntable 2 and play it as well as turntable 1, while
switching the crossfader left to right (ch.1 to ch.2) one record is louder than the other (not by much, but it is noticeable). Now to start with, I thought the reason for this was purely because of the fact that some records are quieter than others - So I matched the PFL (pre-fade listen) meters by adjusting the gain control to make sure the signal of each record was of similar strength. I set all the Eq’s to 0 and channel faders to the same settings but the problem still happened. Does anybody have any idea why I might be getting one turntable/channel/record playing louder than the other ?????

2. When I play a record on turntable 1,with the crossfader to the left (ch.1) and play the Record, everything is fine. When I move the balance fader for channel 1 left to right, the left side is louder than the right side (not by much, but the left side is a nice rich sound with emphasis, and the right side seems ‘dull sounding’). I have checked everything obvious like making sure the balance control on the amp is central, checked all connections etc etc. Does anybody know why i'm getting this problem ?????



The reason why this all came about was because I was trying to do some recording to my pc the other day, and I noticed the problem. The only reason that I can think of that is causing the problem, is that my mixer is knackerd (unless it’s something blatantly obvious which I haven't thought about). Could it be anything else like a stylus problem on the deck? Or a dodgy amplifier? I am quite puzzled over this, so I would be extremely grateful for any advice.





Thanks

A few suggestions

1. Are you using identical cartridges? if cartridges are
not the same this may answer your problem
2. one turntable is out of phase check cartridge wiring
3 swap turntables does the problem reverse or stay the same
4. You have a inaccurate potentiometer in your mixer
5. Check resistance from cartridge to phono plug
for each turntable.
6. Your amplification preamp stage may have a fault
7. Check resistance loading of cartridge for each channel
and each turntable using a multimeter

In such case, if everything was correct before, the first thing you do is feed same signal in both the channels, which are(were) identical and find out where the problem is. Then go further
