How to Fix a Broken Audio Equalizer

An audio equalizer is a necessary part of the modern music experience, and if your equalizer is playing up, you will probably want to fix it as soon as possible. The audio equalizer can often be effected by dirt and debris, or by electrical current faults in the system. If you are unsure about what problem your equalizer is having and want to take it to a professional, you should be aware of the potential cost. Simple repair jobs can be extremely expensive if you don't handle them yourself. The good news is that there are a repairs you can make to your audio equalizer without having to train as an electrician. If you want to try fixing your equalizer at home, following a few simple rules can help you to get the job done safely and efficiently.

Step 1 - Clean the Equalizer

The first step in fixing the equalizer is to ensure that it is properly cleaned. Dirt and debris can settle in the electrical connections and mean that there will be problems in passing electrical current between the connectors. Take a little bit of electrical cleaning powder, which is a dry cleanser for electronic devices, and rub it around the jacks and cables. Clean off any dust, and wipe away any stains which are on the surface.

Step 2 - Fix the Wires

For the next step, you will have to make sure that the equalizer is unplugged from the wall, and disconnected from any audio devices. Turn the machine upside down, and unscrew the bottom panel. This should be connected with just one or two screws, so should come off after a couple of seconds. Once inside, move the electrical connections, and examine the chassis, particularly the cable and wire connections. If you find that any of these is loose, you can replace the wires using a little bit of solder, and a soldering gun. Take your wire, and place it on top of the connector. Melt a little bit of the metal solder, and place it over the wire. Use the soldering gun to ensure that the solder properly melts into the wire, and holds it secure. Check your equalizer again to see whether it works better.

Step 3  - Replace the Fuses

While you are inside the machine you should check the equalizer's fuses. Look to see whether there is any damage to the fuses, such as corrosion or burning signs. If you spot any indications that the fuses might be damaged, remove the fuse, and replace it with a fresh one. Use a multimeter to check the electrical current of the fuses and the wires. If any of these parts reach a greater sum than zero, remove them and replace with ones which can manage the current.
