PA SYSTEM HIRE PACKAGES

PA PACKAGES FIT FOR EVERY OCCASION

If you are looking to hire a PA system for your meeting, conference or event we have a range of packages that we have put together to simplify the choice of PA hire equipment.

Each PA system comes with everything you need including microphones, speakers, amplifiers and mixers as well as all the cables to connect it together.

If you are ‘dry hiring’ and collecting from our warehouse in Suffolk we would be very happy to give you a quick lesson on how it is put together and how to make the best use of it.  Alternatively, we provide a full delivery and setup service to save you the hassle. We deliver throughout Suffolk, Norfolk, Cambridgeshire, Hertfordshire, Essex and London.  For added peace of mind, we can even have our experienced audio-visual technicians on site for your event to ensure you get the best out of the system and that everything runs smoothly.

Choose from our range of PA hire systems but don’t forget, if you need something a little different, or want to add additional items, it is straightforward. Just give us a call and we’d be pleased to advise on the suitability of the equipment and put a hire package together just for you.

ANATOMY OF A PA SYSTEM

A PA system is as it is described ‘a system’ – a series of pieces of audio equipment working together. Each does a particular job in processing the sound but altogether taking acoustic and recorded sound in and pushing it out at the volume you need in the places you need it.

The first link in the chain of sound equipment is the ‘sources’. These could be wired microphones but can also be radio mics, or audio playbacks such as sound connections from a mobile phone, or a laptop computer. When we connect a laptop pc or notebook computer we normally use a little ‘balance box’ to convert the audio signal so that it eliminates any potential problems with hum or interference in the longer cable runs.

The audio signals from the source devices all plug into a sound desk, mixing console, audio mixer or whatever you want to call it. The mixer allows you to adjust the relative volume levels (gain) of each of the microphones and other audio sources. Most mixing desks will have some facilities to adjust the tonal quality of each of the sound inputs. This is often referred to as EQ or equalisation but in ‘old money’ it might just be bass, mid and treble. More complex sound mixers will have facilities for routing the audio signals to different outputs and digital mixing desks will often have a whole range of features that not only allow routing but provide comprehensive EQ, filtering and effects treatment to the sound.

The mixer has combined and adjusted the signals from the various audio sources so that they can be fed onto the amplifier stage. The amplifier's job is to take the signal and increase the voltage and current to levels capable of moving the cone of a loudspeaker so that it can produce noise. Ideally, an amplifier will do this without changing the quality of the sound in any way.

As you have probably guessed the final link in the chain is the speakers themselves. A good speaker will reproduce all of the different sound frequencies equally so it produces a good quality, uncoloured sound. Higher frequencies are more directional in the way they travel through the air so often a speaker specification will have an element of ‘degrees of angle’ as an indication of how it can direct sound over an area.
