What is the function of a tonearm on a record?

The function of a tonearm is to support the cartridge in the correct position over the record and allow it to move inward to the centre of the record while maintaining this position. To do this, it has to perform a few tasks simultaneously.

Where do you put the tonearm on a turntable?

Some turntables require that you install the tonearm onto the turntable itself, others demand that you attach the cartridge to the arm. This is a beginner’s guide so I’m going to assume that both of these tasks have been done for you, as is frequently common nowadays, by the manufacturer.

Where is the tracking weight on a tonearm?

Because the tracking weight, in this finely balanced position, is effectively 0g, you can now locate the arm tracking weight dial which normally sits at the rear of the arm, possibly on the moveable counter-weight itself. Move the dial to zero. Not every arm will arrive with a convenient dial.

How does a unipivot work on a tonearm?

The balancing act that results means that some arms take the radical step of removing the bearings altogether and balancing the arm on a single point. This practice- called a unipivot- ensures that the arm is largely free of mechanical noise but it places further demands on the cartridge and requires careful setup.

What do you look for on a turntable?

Look for the anti-skate control. This can either be a rotating wheel featuring a numbered display or a piece of fishing-type wire with a weight hanging off the end that sits on a bar or some-such on or around the arm (your turntable’s instructions will guide you to what position corresponds to what setting).

What happens if your tonearm is too low or too high?

To allow the stylus to faithfully track the grooves in the intended manner. The tracking weight varies because arm and cartridge weights vary. If the tracking weight on your stylus is too low, it will cause the stylus to jump and damage your record (which is why too low a weight is more harmful that too high a weight).
