Now that you're ready to take your show on the road, you'll need a way to get your music heard... loud! Before you begin your search for a live sound system, consider a few key points first. There are three main parts of a PA system: the preamp section, the power amp section and the speakers.

Most live music clubs provide a house system (probably older than the band) which may suffice for some bands. Other places will require that you bring your own. One thing for sure is that you'll need to make sure whatever is being used will be sufficient enough for everybody to be heard loud and clear.

You're going to have to consider, first and foremost, how many mic/instrument inputs (preamps) you'll need to cover you and your group (If you're a solo artist or duo, there are several PA systems specially designed for you). Count up all of your mics and instruments to be amplified (For instance, 6 mics, guitar, bass and keyboard could use up to 10 inputs).

Once you've figured out how many inputs you'll need, next you'll have to figure how much power it will take to amplify everyone loud enough to be heard over the crowd noise. Speak with those in charge of the venues you'll playing at to get the best estimate of how many people these clubs will hold. A helpful reference is 8 watts of power per person in total capacity (Ex: 200 people capacity = 1600 W minimum).

Now let's talk about power. Powered speakers are great for groups who are always changing venues because they eliminate the need to transport separate power amps as well as the speaker cabinets. Plus, all you need besides powered speakers is a simple, non-powered mixer to perform a live show. Powered monitors are also available which help save time, effort and $$ on more amps.

However, in situations where you need lots of speakers, you'd be better off buying power amps and non-powered speakers. That way you'll be sure you're supplying plenty of extra power for your speakers. Here's a good rule to follow when determining how much power you'll need:

Add up the power handling of the speakers (For example: 6 speakers rated at 200 watts handling each, = 1200 watts). Then, multiply that number by 1.5 (1200 x 1.5 = 1800). The final number will reflect how many watts of power you need to properly power those speakers.

The only other components needed would be speaker cable and speaker stands. A power conditioner is also helpful for high-powered systems.

There are so many options available which can easily overwhelm and confuse first-time buyers, but don't let that lead to an uneducated buy. Be prepared to answer a few questions about what your circumstances and applications are and you will be rewarded with a better sounding, more powerful rig!
