There are two types of speakers that are commonly used by DJs. They are namely active PA speakers, and passive PA speakers. The difference between them is that active PA speakers have built-in amplifiers, while passive PA speakers have to be connected to an external amplifier. Passive PA speakers work just as well, as active PA speakers. In fact, top passive PA speakers, such as those reviewed in this buying guide, have some top technologies built in them. To ensure that you get maximum efficiency from a passive PA speaker, here is a step by step guide on how to connect passive PA speakers to an AMP.
#1 Ensure that the speaker and the amp are matched
Before you connect a passive PA speaker to an Amp, make sure that the two are a match. One of the things that should match is the power (in watts) for the speaker, and the amplifier. As a rule, the power requirements for the speaker and the amplifier should be the same. This is information that should be easy to find on both pieces of equipment. Besides, if you buy both from a single dealer, they should be in a position to help you get an amplifier whose power matches that of the passive PA speaker you are looking to buy.
#2 Connect your amplifier to the mixing console
A mixer is a device that connects a passive PA speaker to sound inputs. Such inputs could be microphones, computers, guitars, or pretty much any other source. As such, they are a critical component when connecting a passive PA speaker to an amplifier. Without a mixer, the whole setup would not be complete. Connecting the amplifier to the mixer is done on the basis of the amplifier mode. For instance, if you choose to connect in stereo mode, then the input and output for the mixer and the amp have to match one-to-one. Simply put, if you are looking to connect to channel one on stereo mode, input to c1 must be matched with input to c1. Other modes have their own requirements too. For instance, in parallel mode, C1 input goes to the output of multiple channels. You can learn more about these modes from the manufacturer’s manual for your amplifier. The key thing to note is that you need to connect the mixer to your amplifier.
#3 Connect the amp to the passive PA speakers
To connect the amplifier to the PA speakers, you will need speakor cables. For best results, go for heavy gauge cables, and also ensure that the cable length between the amplifier and the speaker is not too long. When the cable is too long, the amplifier will overheat, which creates inefficiencies. Now that you have the cable right, connect it to the amplifier and lock it into position. To properly lock it, insert it at an angle where it doesn’t feel forceful then turn it clockwise. It should lock itself in easily. As for where to connect it, the cable should go into the output of the amplifier and input of the speaker.
If you follow these steps correctly, you will have connected your passive PA speaker to an amplifier, and are ready to rock the show.
