Sound & PA Systems

World's Best Sound & PA Systems when needs Powerful loudspeakers are required in many public address scenarios. This could be a presentation, speech, concert, etc. Because there is such a high demand for PA speaker, there are plenty of speaker brands that produce PA speakers. Although these speakers are relatively simple (compared to their more-precise studio monitor and HiFi home-theater counterparts), there are certainly some brands that make better PA speakers than others.

With so many options, it’s tough to cut above the noise. This article aims to share the best PA speaker brands worth knowing about when it comes time to decide for yourself about what speakers you’ll be using. As a performing musician, capturing, mixing, and amplifying your sound involves choosing a live sound system that’s well matched to your music, budget, and the venues in which you play. Whether you're a singer-songwriter performing in a café, a band playing in a local bar or club or a DJ playing weddings, you're going to need a PA system to be heard. In this guide we’ll walk you through all the live sound gear you need, tell you how it works, and help you find the right PA equipment to make your music sound its best.

  • Getting Started:

If you are new to using a PA system, then you’re in the right place. The primary goal is to amplify a sound source to your audience, and we’ll show you how to go about doing that. To get started, first learn what a PA system is and how it’s able to amplify sound without producing feedback. Once you’ve got a hang of the basics, learn a few different examples of PA’s you’re likely seen before.

  • What is a PA system?

A public address (PA) system is for amplifying the human voice. In its simplest form, it has a microphone, mixer, and loudspeakers. It all starts with the microphone (mic), which converts sound pressure to voltage. That means when you speak or sing into the mic, its magnetic force outputs a small amount of voltage. That voltage is then sent to either a mixer or loudspeaker for amplification. Once boosted by a power amplifier, the voltage is so high that it forces the speakers to move and recreate the sound pressure changes which first entered the mic. The result is a much louder sounding voice.

Another way to think about amplification is how the signal level, or its voltage level, is increased at separate gain stages of the system. Gain staging refers to each level of preamplification or volume adjustment found in a signal path. For a PA system, the gain stages are the microphone preamplifier, channel level, mix level, and loudspeaker level.

The voltage starts at mic level and, after being increased by a preamplifier gain knob, is increased closer to line level. Once raised to line level, the signal level is adjusted by a mixer’s level controls. When the mix leaves the mixer and enters the loudspeaker’s amplifier, it is dramatically increased to speaker level and controlled by the amplifier’s level control. The high voltage level causes the speaker to rapidly move back and forth, thus reproducing an amplified version of your original signal. It's made up of several components, and while one system can vary greatly from the next, each one handles these same basic functions:

  • Converting acoustic sound into electronic signals, most often with microphones or line inputs.
  • Processing and mixing these electronic signals, using mixing boards and effects modules
  • Amplifying signals with a power amp
  • Delivering the sound through speakers
  • Monitoring the performance with speakers or in-ear monitors
  • Different PA equipment will have different capabilities, features, and designs associated with each of these functions. Your specific needs will determine what you want out of each.


  • How do mixers work?

Mixers let you connect and control levels that are received from microphones and sent to speakers. Their main function is to bring microphone and instruments levels up to line level and then balance the mix before sending it to the loudspeakers.

  • How to Set Up a PA System?

In this guide, we will show you how to set up a PA system. Whether you’re using a portable speaker with a single microphone, or a large mixer with multiple amplifiers and speakers, we’ll walk you through the setup basics and show you a few examples. Follow the sections below to get started.
