Common Audio Amplifier Problems
"If you own a home audio amplifier, you may be curious about the sorts of problems that have been known to plague such devices. By familiarizing yourself with common home audio amplifier problems, you will be well equipped to diagnose any issues that may occur. Here are 4 of the most common types of home audio amplifier problems.
Home audio amplifiers produce a great deal of heat. As such, overheating is a very common problem with them. Overheating generally occurs when amplifiers are left on for exceedingly long periods of time or when they are placed close to other heating-generating devices. For this reason, it is important to place your amplifier in an area in which it has ample space to breathe. Overheating is also liable to occur if your amplifier's settings have been cranked up to extreme levels
Humming is another common problem that has been known to occur with home audio amplifiers. Humming can be caused by a number of different factors, so it's important to know how to diagnose it. For example, if turning your volume up and down affects the loudness of the humming, the problem most likely lies with the volume control. If the level of the humming remains unchanged despite your volume settings, the source of the problem likely lies with one of the components connected to your amplifier. Humming can sometimes be remedied by making sure your components are securely connected to your amplifier. You can also use a process-of-elimination method by disconnecting each component one-by-one and listening to see if the humming persists after each disconnection. It is recommended that you turn off your amplifier and components while the disconnection process is underway.
Inadequate power supplies are another common source of amplifier problems. Home audio amplifiers use a good deal of power and, if run through the improper type of power supply, they are liable to provide insufficient sound quality and not operate to their full potential. When selecting a power supply for your home audio amplifier, make sure it is capable of handling the type of voltage and electrical current given off by your amplifier.
Incompatible components can cause many problems with your amplifier. In addition to the previously discussed humming, incompatible components can significantly degrade your amplifier's sound quality. Before purchasing a home audio amplifier, take note of the brands and model numbers of all the components with which you wish to link the device and research which brands of amplifiers will work well with them. Online consumer testimonials are arguably the best method of conducting this research, as the Internet is a fantastic source of product reviews. The research may seem cumbersome, but selecting an amplifier that works in harmony with your components will ultimately prove well worth your efforts.
The next time your home audio amplifier begins to act up, you'll have the information needed to diagnose the nature and source of the problem."
