Set up problem?

Looking for some direction, I'm still pretty new at this. I have a Music hall MMF 9.1. On every record I play I hear a lot of noise from the left channel. I get some from the right channel, which to me sounds like a normal amount of surface noise, but the left channel seems like more than that. Could this be a problem with set up?

Thanks for your help,

Eben.

It's hard to say based on your description. It could be set-up. It could be a bad cartridge. It could be a problem with the phono preamp. It could be a problem with the interconnects.

If you don't hear the same problem with other sources, I'd suggest swapping the phono preamp interconnects at the linestage preamp to hear if the noise switches from left to right. If it does, then the problem is at the cartridge or at the phono preamp (if you have a separate phono preamp). Then, normalize the ICs at the linestage preamp and swap the phono ICs at the phono preamp inputs. If the noise follows the swap, then the problem is at the cartridge or with the set-up.

At that point, the only way to determine if the problem is with the cartridge or the set-up is to change the cartridge. However, if you've tracked the problem to the cartridge or set-up, then I'd contact the dealer for a remedy. As I recall, the MMF tables are sold plug-and-play, and the end user shouldn't have to deal with set-up or cartridge problems.

Schipo's correct.

Swapping the interconnects at the linestage will tell you if the problem is with the preamp or in front of it. If you swap the ICs and the problem still occurs in the same channels, then it may be a tube (or tubes).

I'm not clear. When you say you swapped the ICs at the Jolida, do you mean the Jolida JD9? When the noise changed from left to right, was it after you had swapped the ICs the the JD9's inputs from the turntable, or from the JD9's outputs to your linestage preamp?

OK. Then your problem is at the table, either with the cartridge, phono ICs or set-up.

To rule out the phono ICs, switch them at both ends: the JD9 inputs and the table outputs. If the noise stays in the same channel, then the problem is with the cartridge or set-up.

Check to make sure the cartridge leads are connected securely.

If you bought the table from a dealer I'd contact him for assistance.

Or, you could install a different cart and listen for a change in the noise.

Sure thing. Hope you get it worked out.
