After purchasing a power amplifier, I suggest that you follow the following suggestions in order to prevent damage. Also, the tips which I’m going to give will optimize sound quality. Don’t worry, the installation is not very difficult and you don’t have to spend money for hiring a contractor.
After receiving the amplifier, open the box and carefully inspect whether the contents of the package matches what it says in the user manual. There might also be a packing list included. Oftentimes manufacturers will forget to include some cables or adapters which are necessary for proper operation of the product. If one of these accessories is missing then immediately contact the retailer. They might have these accessories in stock and might be able to give you one right away.
Sometimes, the manufacturer will protect the enclosure of the amplifier by applying protective coating. Be sure to remove all this coding prior to the installation. Any such coating might block the evidence of the amplifier and thus the product could overheat. Next, check if there any adhesive steps which can be applied to the bottom of the enclosure. These steps will ensure that the amplifier cannot easily slide from the platform. Oftentimes the manufacturer will enclose these separately rather than applying them to the product. If that is the case then apply those taps prior to the installation.
The first thing to connect is power. Locate the power cord and ensure that they are no marks and there is no damage on the cable. Damaged cables are a fire hazard. If you notice any damage on the cable then replace it right away. Next, double check that the input voltage of the amplifier matches your mains voltage. Some products have switches on the back which allows selecting between different voltages. If that is the case, switch to the right mains voltage. Some manufacturers use wallwart AC adapters rather than power cords. I suggest connecting the DC plaque of the wallwart with the amplifier before plugging in the wallwart. This will ensure that there are no sparks during the installation. Sparks can easily occur when the wallwart is first connected to mains.
After plugging in power, it is time to connect you speakers. When selecting speaker cable, use a thicker gauge then you think might be necessary. A thicker speaker cable will have less cable losses. When connecting the speaker cable to the amplifier, observe the correct polarity of the cable. Do the same while connecting the cable to the speakers. Finally, it is time to connect your source to the amplifier. Always use high-quality cables when making the connections. High-quality will in the end lower your costs because you don’t have to swap out fault cables nor will they be bad connections.
Finally, turn on the amplifier and slowly raise the volume. Do not set the volume to maximum right away because that could damage your speakers. Initially, set the volume fairly low and then while your sources active, slowly increase volume.
