Behringer Ultracoustic acx1800 cd right input not working. Any ideas of what blew?

If the right input on your Behringer Ultracoustic ACX1800 CD is not working, it could be due to a number of reasons, including:

1. A faulty cable or connection: The problem could be as simple as a loose or damaged cable. Try swapping out the cable with a known working cable or check the connection to ensure that it is secure.
2. A blown fuse: The ACX1800 CD has a built-in fuse that protects the internal components from power surges or other electrical issues. Check the fuse to make sure it is not blown and replace it if necessary.
3. A damaged preamp or amplifier circuit: If the problem is not with the cable or fuse, it could be due to a damaged preamp or amplifier circuit. This can be caused by a number of factors, such as overheating, power surges, or other electrical issues. In this case, you may need to take the ACX1800 CD to a professional repair technician to diagnose and fix the problem.
4. A faulty right channel input jack: It is also possible that the right channel input jack itself is faulty. This can be caused by wear and tear over time or physical damage. In this case, you may need to replace the input jack or have it repaired by a professional technician.
