Rotel RB-850 Amplifier F.A.Q.

How do I connect my Rotel RB-850 Amplifier to a preamplifier?

To connect your Rotel RB-850 Amplifier to a preamplifier, use high-quality RCA cables. Connect the output of the preamplifier to the input of the RB-850, ensuring that you match the left and right channels correctly.

What should I do if my Rotel RB-850 Amplifier is not powering on?

First, check that the power cable is securely connected and that the power outlet is functioning. Ensure the amplifier's power switch is in the 'ON' position. If it still does not power on, check the fuse and replace it if it's blown.

How can I troubleshoot a humming noise coming from my Rotel RB-850 Amplifier?

Humming noise can be caused by ground loops. Ensure all components are connected to the same power source. Use a ground loop isolator if necessary and check for any faulty cables or connections.

What is the recommended maintenance routine for the Rotel RB-850 Amplifier?

Regularly dust the exterior with a soft cloth and ensure ventilation openings are clear of obstructions. Inspect connections and cables periodically for wear or damage. Consider professional servicing every few years for optimal performance.

Can I use the Rotel RB-850 Amplifier with different speaker impedances?

Yes, the Rotel RB-850 Amplifier can handle speaker impedances of 4 to 8 ohms. Ensure your speakers are within this range to avoid overloading the amplifier.

How do I bridge the Rotel RB-850 Amplifier for mono operation?

To bridge the Rotel RB-850, connect the positive terminal of the speaker to the positive terminal of one channel and the negative terminal of the speaker to the positive terminal of the other channel. Ensure the amplifier is set to mono mode.

What should I check if one channel of my Rotel RB-850 Amplifier is not working?

Check the input connections and speaker wires for the affected channel. Ensure the balance control on your preamplifier is centered. Swap the left and right inputs to see if the problem follows the channel or stays with the amplifier.

How can I improve the sound quality of my Rotel RB-850 Amplifier setup?

Use high-quality interconnect cables and speaker wires. Ensure proper speaker placement and acoustics in the room. Consider using a dedicated power line for your audio equipment to reduce electrical noise.

Is it normal for the Rotel RB-850 Amplifier to get warm during operation?

Yes, it is normal for the Rotel RB-850 to get warm during operation due to its Class AB design. Ensure it is well-ventilated and not enclosed in a confined space to prevent overheating.

What precautions should I take when cleaning the Rotel RB-850 Amplifier?

Ensure the amplifier is powered off and unplugged before cleaning. Use a soft, dry cloth to wipe down the exterior. Avoid using liquid cleaners or solvents that could damage the finish or electronic components.
