How do I balance the tonearm on my Rotel RP-840?

To balance the tonearm, first ensure the counterweight is properly attached. Lift the tonearm from its rest and adjust the counterweight until the tonearm floats horizontally. Then, set the tracking force by rotating the counterweight dial to match the cartridge specifications. Ensure anti-skate is set to the same value as the tracking force.

What should I do if the sound is distorted or unclear?

If the sound is distorted, check the stylus for dirt or damage and clean or replace it if necessary. Ensure the cartridge is properly aligned and all connections are secure. Verify the tracking force and anti-skate settings are correct. If the problem persists, consider inspecting the amplifier and speaker connections.

How often should I replace the belt on the RP-840 turntable?

The belt should be replaced approximately every 3-5 years, or sooner if you notice speed inconsistencies or visible wear. Regular inspection for signs of cracking or stretching can help maintain optimal performance.
