Maybe too close to the speakers causing "feedback". Otherwise
need more info on the noise!

Grounding issue

The preferred approach is to run a ground cable from the turntable to the ground post on the back of your preamp or receiver. This keeps buzz and hum out of the audio signal. If your receiver doesn't have a ground post, you'll have to connect the ground to one of the RCA signal jacks. In both cases the question is, when you have two grounds, which one to connect? You'll have to determine this by trial and error. My guess is you'll get the best results by connecting both, so start with this arrangement. Connect the turntable's audio cables from its RCA jacks to the receiver, select the phono input, and turn it on (with the volume turned down). Turn up the volume until you can hear hum or buzz. Then connect a piece of wire to the ground post on the turntable panel and touch the other end to the ground post on the receiver or to the RCA jack/plug's outer ring. If the hum/buzz goes away, you're good to go and can connect the wire permanently. If not, try the ground cables individually and use the connection that works best.

How do i hook a numark tt 1625 turntable to a regular home stereo amplifier...does the ground need to go into anything specific?

Turntables require a special input in the amp (usually marked PHONO) because they require high gain and different equalization - and yes, that ground wire has to go to ground unless you want to get a super annoying 60Hz hum from it!
If your amp doesn't have a phono input, you're going to have to go out and get a phono pre-amp and connect it between the turntable and the amp.
Best of luck!

Hi there! i just bought a numark tt1650 and an ortofon arkiv cartridge, connected it properly to my old technics a700mk2 amplifier (phono, grounding and all that) but it still has a buzzing problem...

Try connecting the turntable to one of the other inputs like CD / tuner etc and see if the buzzing disappears. if so then your turntable has a built-in pre-amp so it can be connected to any input except 'phono' as this would obviously be used for turntables without a pre-amp.
a lot of modern turntables now have built-in pre-amps to compensate for certain amps and receivers made without a phono input and can now be connected just like a CD player, tuner etc.

hope this helps.

Tone Arm acting as arial

A metal tone arm has a ground wire that connects it to the back of the stereo via the Turntable chassis. If this wire is broken (inside the deck of the turntable) or the ground to the stereo is not done, you can have this issue. No, the ground through the audio connectors is not sufficient.

During vinyl play the sound will drop Numark TTUSB

sounds like the needle is worn down...try to replace the needle.....the buzzing sound often comes from open groung connections...that can come from the cartridge itself to the jacks on the back of the unit....bad ground and buzzing is normal for turntables and will also dramatically affect your sound level because the buzz or groung fault is higher than the sound being picked up by the grounds can be checked with a meter set to check for continuos line feed with no breaks in the lines.....if you find a broken line ...then that's your is a very simple repair....if the ground problem is in the cartridge...replace the cartridge which comes with a new needle as's cheaper to buy it that way in stead of just bying a needle...if the ground fault is anywhere after the cartridge...then it's just a mater of replacing or repairing the line..again..very cheap repair....also...if the cartridge just clips on to the shell, sometimes it makes bad connections there too....that can just be cleaned with a little sand paper and it will work again....good luck

No signal going into mixer.

Did you buy the gear new? If not, the issue might be with the meter. Also, sometimes the signal isn't loud enough to engage the meter, so try cranking up the Trim and Volume (Master & Line), of course, make sure the volume on your amp is down, so you don't blow anything.

Good luck.

Second hand decks

The unit should not be making any sounds like that. It sounds like the timing is off for the gearing underneath the platter. It may be as simple as cleaning the existing grease on the mechanism and re-lubing. The existing grease may have gummed up a bit not allowing the parts to move freely. Take of the bottom and look at the condition of the grease.
