Pa system setup guide

Actions Shares. No notes for slide. STEP 1 Plug the kettlelead into the mains and the desk. Kettleleads are used because they are able to transfer more power. The left output connects to the left speaker and the right output to the right speaker. Desk outputs XLR cables 5. I am using active speakers because they have a built in amp. Passive speakers would be more commonly used in the rig as they are lighter.

The input on the desk can vary depending on your sound source, for example whereas a CD player uses a line input, a microphone would use an XLR input. Quarter inch jack adapters 8. The gain controls how much sound comes into the speakers. Repeat for each channel. Peak meter This will allow equal sound to exit the speakers. Total views 5, On Slideshare 0. From embeds 0.

The midrange is a little boxy which will be an issue for live musicians and speech, however, the system was designed for music and DJ applications and for this, the RPGK is perfect. The system is designed for these sorts of music applications where you want to get a party started.

The Rockville RPGK system is not recommended for live music applications due to the lack of features singers and instruments require. Need some help to understand your watts from dBs? PA is the acronym used for a public address system which refers to a speaker or speakers used to produce sound speech or music to an audience. A PA system can be made up of a single speaker with a microphone, MP3 player, or even a multiple speaker set-up found at concerts and festivals.

Wattage is often the primary metric people look at when buying speakers. Watts is the measurement of audio power transferred from an amplifier to a speaker. Wattage is important because it determines how powerful your speakers are. Watts is not a measurement of volume — that is measured in decibels dB. RMS is the average power output an amplifier will produce while peak is the maximum power output.

Some manufacturers will include a Program Power P. This is an irrelevant metric and should be ignored. In simple terms, a decibel is a measurement to which how loud something is. Similar to how miles is used to measure distance. This universal standard for calculating sensitivity is by measuring 1W of sound at 1 meter. The sensitivity and wattage specs should be considered together to determine how loud and efficient a speaker will be.

Take a look at out list of the loudest Bluetooth speakers on the market. Frequency response is a difficult spec to determine the sound profile of a speaker on paper. Human hearing can pick up frequencies from 20Hz to 20kHz, which is often referred to full-range as this is the full range of human hearing. Many speakers list a full-range response but what this actually sounds like in practice is something completely different. This is because a frequency response is not perfectly linear.

You can have a 20Hz to 20kHz response with some frequencies being louder than others. So listening to how a speaker performs is very important to determine exactly how much of the frequency response is audible and at what levels.

You can read more on frequency response and how it affects your music in our comprehensive guide. EQ stands for equalization and can be used as a noun or a verb in the sound industry. As a noun, it describes a piece of equipment used to adjust audio frequencies. As a verb, you EQ a voice or instrument to boost or cut frequencies to get your desired sound. On all professional mixers, as well as some entry-level units, you will have gain and volume on an input channel. At first glance, they appear to do the same thing — turn the volume up and down.

They do, but for different uses. Take a garden hose with an attachment on the end. By opening and closing the hose attachment you can increase and decrease the volume of water that comes out. However, the tap determines the pressure you send to the actual hose attachment. Think of gain as the tap and volume the hose attachment. A pad is an attenuation switch which allows you to decrease the input of a channel or piece of equipment. Usually, a pad will range from dB to dB depending on the mixer.

However, the most common is dB on a mixer input channel. A pad is useful for instruments which produce a high-gain output — especially guitars, keyboards, and sometimes vocals.

A speaker driver is just another name for a speaker. Usually, we refer to a speaker as the whole unit while the driver is the actual speaker or tweeter inside the enclosure. An XLR is a three-pin audio connector used in professional audio equipment. Matt is a sound engineer and self-confessed vinyl-junkie!

PA speaker drivers need to resist considerably more stress than your hi-fi at home, and move a lot more air, so their construction is crucial.

And do make sure they have mounting holes for speaker stands! Speakers come usually in either 4, 8 or 16 ohm variants. The only thing you need to take care of is that this number matches your amplifier.

Most amplifiers have a switch to set the output to the right ohm for your speakers and you should look for that. Also the wattage on the amplifier always state at which ohm it delivers that power. So if you have a power amplifier that delivers W at 8 ohm, but you speakers can take W and are 4 ohm, you will probably damage your speakers. In venues in the past, I have seen sound engineers using diagrams and doing number-crunching beyond what I thought possible, and the whole thing still ended up sound bad.

Experience and working with various sound guys particularly, a house engineer at a large concert venue who imparted the following knowledge to me 20 years ago means I can share with you you how I go about speaker placement. And while I have no formal qualifications in this area, I do know what sounds good. So here goes:. Firstly, place your speakers as far left and right from your audience as you can go, pointing in to the room slightly. For example, the corners of the stage or near the side walls of the venue.

Again, this makes total sense if you think again about moving air. If you do not mount the speakers above the audience, you will blow all the moving air into the first row of people, who will be deaf soon, but the sound will not carry to the back of the venue.

If you put the speakers too close together you will have to take care that they do not angle against each other and do not cancel themselves out in some places.

Now some speaker sets especially active sets come with a pair of subwoofers matched to the speaker pair. These are simple to place; you simply leave them on the floor below the main speakers. In most cases you can put the main speakers on top of the subwoofers and use a simple connector pole or extension pole to get them high enough in the air.

Indeed, most PA subwoofers are made that they can safely be placed on the floor and even use the floor as a resonating membrane. With a single subwoofer, I tend to place it in the middle between the main speakers. By sitting on the floor and using the floor to help with resonance, they can even amplify the bass experience.

Last updated 27 March, Very different to the type of amplifier you may have in your home stereo, PA power amplifiers are designed to run at high levels for long periods of time.
