Audio power amplifiers are an essential component. They are the link between your audio source and your speakers. The quality of your overall audio system depends a lot on the quality of this essential part. When purchasing an audio amplifier, do your proper research. Don’t purchase one because it might be very inexpensive. Rather balance the performance of the amplifier with the cost. Also, keep in mind the wattage rating of you speakers and the size of your room. These factors will impact your choice when picking an audio amplifier.
However, just as important as purchasing a good-quality amplifier, the correct installation is also crucial. If an audio amplifier is not set up properly then the amplifier can be damaged or sound can be degraded. I recommend to follow these tips which I’m going to outline below in order to optimize performance of your amplifier. The first crucial part in achieving proper performance of an amplifier is having a good power source. An amplifier by nature is power-hungry. If you have purchased a Class-D amplifier then the power requirements are not as strict as when purchasing a class-A amplifier. That is because Class-D amplifiers have far higher efficiency and therefore don’t require nearly as much power. Also, these types of amplifiers usually are better equipped to suppress ripple on the power line. However, class a amplifiers oftentimes can pick up noise which is contributed by the mains power line.
If you do have a class a amplifier then I recommend using a clean power source. This is a component which plugs into your power line. Then the amplifier power cord is plugged into the clean power source. This clean power source will remove ripple and also protect the amplifier against damage from power surges. Using the clean power source is also a good idea when using a Class-D amplifier though by no means necessary. When installing a Class-D amplifier, I still recommend using at least a surge protector to provide protection against power surges.
Next it is important to use proper gauge speaker wires. The thickness of the speaker wire will impact the performance of your speakers. It also impacts power losses due to the cable. If you are operating high-wattage speakers then purchase thicker cable. That will minimize losses inside the cable. When making the cable connection to the amplifier, always connect the cable with the correct polarity. I would recommend to purchase cable which is marked on one side in order to be able to observe polarity. Do the same when connecting the cable to the speakers. Having every speaker connected properly is crucial.
Finally, don’t block any heat vents of the amplifier. Allow proper radiation of heat through air ventilation. If air cannot move freely around the amplifier, overheating can occur which in turn can damage your amplifier.
