Regardless of what product you purchase, if you have spent a significant amount of money it is well worth protecting your investment. In this article, I’m going to focus particularly on audio equipment such as amplifiers or DVD players. Also, loudspeakers can be quite expensive if you go for higher-quality models. Some people spend in excess of $100,000 on their equipment. Obviously, it makes good sense to take some measures for protecting the equipment.
There are several ways for protecting your investment. Obviously, when installing your equipment I always recommend hiring a professional. You can easily damage your equipment if you make the wrong connection or configure the equipment incorrectly. As an example, some devices have to be switched to connect to either 120 V or 220 V AC voltage. If you have a device that is configured to connect to 120 V and plug it into an outlet which has a higher voltage then your equipment can get fried. Also, if you don’t know how to connect different components then you better leave that to professional. It is all too easy to connect a digital output to an analog input and thereby damage the input stage. Also, you cannot connect an amplified audio output to a non–amplified input. That most likely would overload the input stage. Further, speakers which don’t incorporate an amplifier cannot directly connect to a low-voltage audio output.
I also recommend using a surge protector or uninterruptible power supply for connecting power. Spending the extra money for these components is well worth it because during a thunderstorm your mains power line can actually carry a higher voltage which can very easily damage all of your audio components. A surge protector will protect your equipment to some degree. However, an uninterruptible power supply or clean power source provides additional protection. You will want to decide which of these to purchase depending on how much money you spend on the equipment.
Finally, make sure that there is no easy access for thief into your home. Many people specialize in stealing high-and products including audio products. Make sure that you take pictures of your equipment and also hopefully take out some insurance. Note all of the serial numbers of each component and register those with the manufacturers. Knowing the serial number can be important in case a stolen component is found later on.
