What is an audio system?
Also known as a PA (public address) system, a sound system comprises multiple audio elements. It is an electronic system that works collectively to produce, control, and project sound.
Each element of an audio system plays an important role in the overall sound quality and reinforcing live sounds. The quality of each component will ultimately influence the final sound output. Hence, a sound system must be chosen and set up meticulously for optimal performance.
If you are organising an event, the sound system provided by the venue may not always be adequate. A high-quality sound system can give audiences an immersive sensory experience that leaves them feeling impressed and stirred by your event. Without a suitable PA system, your guests will not be able to hear anything clearly, regardless of how outstanding your visuals are.
Moreover, event audio systems and home audio systems are different because the former often requires higher volumes, resulting in feedback and distortion. Therefore, your event must be equipped with a sound system capable of handling such issues.
What are the elements of a sound system?
Audio Sources
Audio sources can be any device that generates sound, such as a microphone, phone, computer, or musical instrument. The quality of the audio source will affect the quality of the output. Thus, it is important to choose high-quality audio sources.
Microphone
A device that picks up on sound and captures sound waves, a microphone then translates the sound waves into electrical signals that are then amplified and processed. Then, these signals are sent to a mixer where they are mixed and adjusted. The number and types of microphones required will depend on the type of event.
For example, dynamic microphones are robust and can handle higher sound pressure levels, making them suitable for live performances, while condenser microphones are sensitive with a wider frequency response. Ribbon microphones have warm and natural output; clip-on microphones are discreet and inconspicuous, ideal for cosy settings. Other than that, shotgun microphones are perfect for noisy and lively events, as they help to reduce ambient noise, whereas wireless microphones allow for unrestricted body movement.
Audio Mixer
Also known as an audio mixing console or soundboard, an audio mixer is the heart of a sound system that controls the level, tone, and volume of each audio source so the audience will hear balanced, harmonious output. Featuring an electric console that processes, mixes, and combines audio signals from multiple sources, sound engineers or technicians then amplify and route those signals to the speakers.
Audio mixers can also be used to balance the overall output, adjust volume and feedback, and add effects. Depending on the scale, you will need a soundboard with sufficient channels to manage the inputs of your event.
Amplifier
An amplifier is an important aspect of a sound system, as it amplifies audio signals from the audio mixing console before the speaker can broadcast the sound at a higher volume. It electronically boosts and adjusts the sound to the desired levels.
Speaker
This device converts electrical signals from the amplifier into soundwaves and distributes the sound where intended. Speakers are a crucial part of the sound system, as your audience will not be able to hear anything otherwise.
Passive speakers require external amplifiers, while active speakers have a greater control of sound quality with built-in amplifiers. The best type of speaker suitable for your event will depend on the type and size of your venue and event.
Subwoofer
A subwoofer is a powerful speaker which replicates and broadcasts low-level bass frequencies that normal loudspeakers are unable to. Only one subwoofer is necessary for an event smaller in scale, whereas more may be needed for louder or audio-heavy events.
Audio Switcher
As its name suggests, an audio switcher changes the sound output by switching between different audio sources. However, this device may only be necessary for more intricate sound systems where the audio output needs to be managed thoroughly.
Microphone Preamp
A microphone preamp will boost the audio signals from the microphone to a level where the sound can be recorded and processed. This accessory is useful for events with live sounds, as it captures clean and accurate signals.
Cable
Often overlooked and forgotten, cables are easily one of the most important parts of a sound system, as they link different components of the audio system together. For example, an audio cable connects the amplifier to the audio mixer and the soundboard to the loudspeaker.
Renting a Sound System for an Event
Although many elements make up a sound system, not all of them may be necessary for an event. It depends on the scale of your event and the auditory experience you would like to create for your guests.
High-quality sound is crucial in ensuring the success of your event. When you rent an audio system with Multi Image, you can focus on managing your event and leave the nitty-gritty of sound systems to us.
