A Brief Guide to PA - Part 1 - Active Vs Passive

Updated: Aug One unique feature of PA systems is that no two are alike. This guide will explain the basic parts and functions of the most common type of PA systems, basic setups with ground-supported speakers.

What is a PA System? By , multiple units were installed throughout the Comiskey Park baseball stadium in Chicago, both to make announcements and to provide musical interludes. Charles A. Comiskey was quoted as saying: "The day of the megaphone man has passed.

Any system of one or more speakers designed to replicate audio or speech to a group of people qualifies as a PA system. The first component that comes to mind when thinking about PA systems is the most important one, the speakers. PA speakers come in countless different shapes and sizes. Each type of speaker serves a different function within the system, but each depends on the other.

In basic PA systems, the main speakers are either placed on speaker stands or mounted on top of the subwoofers. Main speakers in your basic PA system are normally sized between 10"" with a smaller tweeter speaker above the woofer. Subwoofers are larger than the main speakers and produce lower frequencies than the mains.

Subwoofers are typically 15"" speakers, although dual 12" subs have become more common. To separate the sound of the subwoofers and mains, a crossover unit will almost always be employed.

The crossover is usually rack-mounted and separates the signal going through it by frequency, sending lower frequencies to the subwoofers and higher ones to the mains.

An important part of tuning a PA system is selecting the correct crossover frequency for the room in which the PA is situated. Stage Monitors are usually positioned near the performer or speaker to help them hear themselves. They are on a separate mix than the mains and subs, also known as the front-of-house speakers.

Many main speakers are purpose-designed to also act as stage monitors if so required. Stage monitors are usually on the ground tilted at an angle towards the performer. PA speakers can either be passive or active. Active speakers have an internal amplifier of their own while passive speakers have no internal amplifier and require an external amplifier to convert the line level signal of the mixer to a level where it can drive the speaker to the necessary volume.

Amplifiers can be an expensive item, but deservedly so. A mixing console is one of the most important parts of a PA system and like other PA components, the options on the market are endless. A mixing board will have a set number of channels and is responsible for combining sounds, routing, and changing the volume level, timbre tone color , or dynamics of many different audio signals.

A mixer can provide phantom power for capacitor microphones, pan control on each channel, and monitoring mixes, for the stage monitors. Most mixing consoles will have left and right main outputs and individual outputs known as auxiliary sends, most commonly used for stage monitors or effects.

To connect the components of a PA system and transmit an audio signal, various cabling is required. Some amplifiers can have a form of RCA outputs called banana cabling.

Using the correct cabling when setting up a PA is vitally important. In the worst-case, using the wrong cables or connectors can be dangerous.

An optional, yet common component of a typical PA system is effects. Many modern mixers will have onboard effects, however , effects paired with a PA system are usually outboard, meaning stand-alone units.

Common effects paired with a PA system are reverb, compression, delay, gates, and equalizers. PA systems have various applications , thus there are a variety of common sound sources for PA systems. The most common source is the sound from a microphone. Microphones also have a variety of uses and placements, ranging from vocal mics, instruments mics, and room mics.

PA systems are also great at reproducing already recorded music. Music can be played through a PA system by feeding the sound through one or more channels on the mixer. The signal flow of audio within a PA system is inherently simple, however , there are many points at which a novice might become confused.

Every PA system is different, however , a typical signal flow is depicted in the figure below. Operating even a simple PA system can be frustrating, although rewarding. For many small-scale events such as speeches and conferences, little to no tweaking of the settings on the mixer is required after soundcheck.

However, for large-scale productions such as concerts, it is imperative that an engineer is present to mix the sound for the duration of the event. Due to the complex nature of music, vital changes to the PA systems sound are often required constantly. Interested in learning more about PA systems?
