Why ground turntables




















Thereafter, place the cartridge holder to the tone arm and tighten it slightly. To help the tone arm smoothly floats, you should stabilize the weight of the cartridge.

Do not forget to open the tone arm from its resting post and rotate them on the rear of the tone arm. When you see the tone arm floats, you will know that you undertake the right way.

Then, get rid of the stylus when performing. In fact, every cartridge design has different tracking force specification which ranges between 1 and 3 grams. Therefore, you enable to use the tracking force indicator on the tone arm or a stylus force device is the best choice. Then, you can make the tracking force in each of the cartridge specifications as well.

Anti-skating handles are placed on some turntables. Generally speaking, a skating-resistant handle recompenses for the skating force which puts the tone arm to the center of the record player when spinning. Also, this will help the turntable reduces much-unbalanced pressure on the sides of the record groove.

You do not need to adjust the skating-resistant control because this is a part of the tracking force adjustment. The Dual turntable is a great example of this description. Put the left and the right channel which are white and red connectors output under the turntable to the phono on the back side of the amplifier or the receiver. If your turntable does not have any phono input, then you should use a phono pre-amp input instead.

Please keep in mind that you should not connect to other input equipment as it will damage your turntable for the upcoming time. In general, a single turntable ground wire should be attached to the ground post or a chassis screw and the turntable on the back side of the amplifier or the receiver as well.

You have already identified how to ground a turntable as well as how to set up a new turntable, you may feel comfortable and proud to handle these tasks. However, you should not forget to keep your new turntable are durable, and you also still enjoy great sound quality.

We have some maintenance tips that probably help you. You should use high-quality substances like the Discwasher to wipe down your turntable. The kit will support you maintain the lifespan and the quality of your devices. Clean your record player on a regular basis to make it lasts forever. Some people also miss out the needle needs to be cleaned as well. However, the needle is also important to adjust the sound quality of your turntable. On the Thorens TD , the ground wire is not separate.

It's part of the RCA cables. Same on the AR-XA turntable. McLover , Jan 12, Location: Rochester,N. I converted my TD to a seperate ground wire. I had to disconnect the ground from the right channel shield. I am still waitng for a belt,so I have not tried it yet. Hopefully I won't have any hum Rhythmdoctor , Oct 18, Location: Sacramento, Ca. Six String , Oct 25, I need to know where to connect a wire from enclosed case of turntable to the reciever.

I have grounded my turntable to my preamp but I still have a very annoying hum. Any advice? I have a pair of Gemini II turntables and only one produces a hum after its been on for about 20 minutes even though they are both grounded to my mixer. Will internally grounding the turntables solve this problem? How do I go about doing this myself? Your email address will not be published. Notify me of follow-up comments by email.

Luckily, ground loops are not hard to avoid. Any untrained ear can clearly hear the difference Think of the 60 hertz hum as an elephant rolling around the savanna, low and slow, and think of the hertz as an angry wasp. Step 5: Make A Connection Remember way back in step one, when you turned your turntable and amplifier off?

This current gives rise to a voltage, because of the finite resistance of the signal wires. At the amplifier input, it will see a voltage which is both the pickup voltage, and some of the environmental buzz. The ground wire earths the chassis of the turntable, mainly the tone arm, to reduce this voltage.

Its resistance is lower than the signal wires, but more importantly, it earths the chassis, which is then weakly coupled to the signal wires. With the earth wire connected, because of the fairly low and independent resistance of the earth path, the environment might manage to induce only a fraction of a volt on the tone arm and chassis.

This has to pass through the stray capacitance onto the signal wires, so the effect is much reduced. Connecting the earth wire to the RCA cable shield at the turntable might help a bit, but it forces this induced current to flow on the cable shields, which will transfer some voltage to the signal path. There are no wavelength-effects, so it should yield to conventional analysis.

The shielded wire that runs from the rear of the turntable up through the tonearm is NOT well shielded. If you connect the cable from the turntable to the preamp, the residual hum and noise might be acceptable but most likely isn't. Especially on a turntable with a shaded-pole motor and a non-grounded AC supply cord. Now attach the ground wire from the turntable to the preamp ground screw provided and marvel at how quiet everything suddenly got.

Note that you do NOT want to connect any of the wires going to the cartridge to turntable chassis. The signals from a standard magnetic phono cartridge are quite low low mV and even less for a moving-coil cartridge. Any current that you inject into the shield wire is essentially in series with the signal and can severely degrade the hum and noise performance of the system.

I spent a lot of my younger years working as a radio broadcast assistant engineer and records are what the station played.
