Remove the red and it goes quiet? Put the red into the left channel, what happens? Put the left plug into the right right socket, what happens? Put everything back to the feedback, power off and remove the turntable cartridge, what happens?

This proves whether it is the cable or the internal electronics of the amp, or the wiring further up to the stylus cartridge.

you are the only one with the issue

I'd fix the tonearm issue first before using it to decide you have a feedback-related issue with one brand of cartridge. I can't say how that would be fixed.

Feedback? Like airborne sounds from the speakers vibrating the turntable and being amplified through the speakers? The biggest downside to old-school vinyl use is that possibility and the workarounds we had to use to prevent it. Acoustic and physical isolation are the only solutions.

My Technic 1200's are only playing out of one speaker at a time.

Clearly there IS a setup issue. Take serrato out of the loop for the moment and the mixer. Plug each deck (one at a time) into a hifi with a MM Phono input. Are you getting stereo? If yes, you know the decks are ok. Now reset the mixer completey. All eqs and pans including volumes to 12 o clock position and volumes to 0.
Make sure you connect deck one to a red and white of one phono input channel. Do not use 1 channel from phono and 1 from line. Use both left and right of the phono chanels.
Ok, now hook up the mixer to the amp. Keep the x-fader on channel 1 and concentrate getting a good stereo signal from this one chanel. Now do the same for the other cahnnel.

This should hae helped you to get up an running, if not narrow down the problem.

Make sure your 2nd turntable is connected to the PHONO input of your DJ Mixer or Receiver. If you have it connected to LINE IN or AUX IN, the turntable will be very low, as this model requires a phono pre-amp to amplify it's signal.

If this is set up correctly, then you might want to check your cartridge. Can you swap the cartridges out to see if the problem remains on the same turntable, or if it switches to the other turntable. If it switches, then you know the problem is with the cartridges.

If that checks out ok, you might have an issue with the RCA cables or Tonearm or both. At this stage, I would suggest taking it to a service center for assistance.

Technics 1210 feedback/grounding problem

Since you've already replaced your RCA cables, and tried different cartridges, the only other thing that would cause this type of issue is your tonearm. It's probably on it's way out, and will need to be replaced shortly.

You can obtain a replacement tonearm HERE, however, it's rather difficult to replace the tonearm without experience or knowledge on soldering.

Good luck!

Technics Trouble... Please Help

You will have to replace the RCA cables on your turntable. You can try to do this yourself, however soldering experience is required. You can purchase the parts HERE - and install yourself, or try to find a reputable service center area to replace the cables.

A word of advice, try not to use the original RCA cables that are installed with the turntables, as they aren't of the greatest quality. Try and put a better brand, or use the MOGAMI cables, available HERE.

Have fun!

Technics 1210 feedback problem hollow noise ??

More than likely it's your RCA cables, or it could be a tonearm or cartridge issue. First try and swap out the cartridges on your turntable, and see if the problem persist. If it does, then you can narrow it down tot the tonearm and RCA cables. Since the RCA cables are easier and cheaper to replace, I would suggest doing this first - You can try to do this yourself, however soldering experience is required.

If the problem persists, then the issue with your tonearm, and replacing the tonearm involves a lot more in-depth work, and I would only suggest having it done by a profession. You can buy the part HERE, and bring it with you to the service center, to minimize your cost.

There is nothing else that would cause this kind of problem except one of the 3 (or combination). So, by a process of elimination, you'll solve the problem.

Have fun!

Could be one of 3 issues:

1) Tonearm
2) RCA Cables
3) Cartridge/Styli

I generally tell people to try different cartridges first. If that doesn't work, then you know it's either your tonearm or your RCA cables. 80% of the time, it's the RCA cables. It's very hard to determine which one it is at this point without opening her up and putting on some new RCA cables to test. If it works, then your good. If not, then you know it's your tonearm, and will need to be replaced.
