Connecting an audio amplifier might seem trivial but there are a few considerations that you should be aware of in order to avoid mistakes and in the worst case damaging your amplifier. Just spent a few minutes to read this article to find out what you should know for a proper set up.
When taking the amplifier out-of-the-box, be sure not to rip any cables which were attached to the amplifier from the amplifier. Sometimes manufacturers will attach cables to the unit prior to packaging the product. In this case by not properly removing the unit from the box and actually damage some of the connectors.
Make sure to remove all of the Styrofoam and packaging from the amplifier. Next, verify that the voltage of the power supply matches your mains voltage. Sometimes manufacturers will ship products which were not designed for a specific mains voltage in which case plugging in the amplifier can actually damage it.
Next, place the amplifier on a solid surface which is stable enough to prevent the amplifier from sliding and dropping down to the floor. Now it is time to establish the connections to you speakers and your audio equipment. Make sure that the amplifier is switched off while you make the connections. If the amplifier was switched on while you plug in audio then you can actually damage your speakers by creating a loud plopping noise.
When connecting the speakers with the amplifier, make sure that the speaker cable is long enough to allow for some slack. This will prevent you accidentally tripping over the speaker wire. Also, pay attention to the polarity of the speaker cable. Usually the speaker cables marked on one side with the color. This will allow you to tell the two strands of speaker cable apart from one another.
Both the speaker clamp terminal at the loudspeaker as well as speaker jack on the amplifier will be color-coded. Make sure that the colored strand of the speaker cable is connected to the colored terminal on both speaker and amplifier for each speaker. This is crucial in order to have the same polarity on each speaker.
After you make the connections, set the volume of the amplifier to a minimum setting. Then establish a connection between you amplifier and when your source. Use some good-quality RCA cable connection. If you have professional amplifier you might have a balanced connecting cable. Use this can connecting cable instead. Now it is time to fire up the amplifier and take it for a spin.
