Basic sound system for events and conferences | AVVIETNAM

Dec 29, 2020

The sound system is an indispensable factor in events and conferences, especially the large-scale ones which have a large number of audiences and attendees. Thus, the sound system needs to be invested in designing and construction. Let’s check out the basic sound system for events and conferences through AVVIETNAM’s article.

Overview of a basic sound system for events and conferences

Audio signal receiver and sender

Audio signal receiver and sender including VCD player, CD player, MD, Microphone or other peripherals that have a sound line out and line in.

Audio signal mixer

Also called a mixer table. It's an audio console, there are a lot of knobs, faders (faders is the changing levers to adjust the effect in sound and lighting equipment), and jacks. If you notice, you will see the vertical of the table (standing in front of the mixer table), each corresponding fader has buttons along with it. Those are the adjustment buttons for EQ (Equalizer - adjust the sound frequency), Balance button, AUX button, FB button,... Each button may be designed differently depending on each type of mixer and each manufacturer. And each fader has its own corresponding buttons. Besides, there are also total faders of sounds, group faders of sounds,...

Equalizer

After the audio signal passes through the mixer table, it will be brought down to this equalizer. The main usage of this set is to cut excess frequencies, noise,...

Process of setting a basic sound system for events and conferences

Through the diagram below, the input signal into the mixer will be mixed and output by 2 main out (stereo out) to the equalizer, 2 single lines, or 1 double line. After leaving the EQ, the signal goes directly to the crossover (other effects, if any, also have a serial turn here, before entering the crossover).

From the crossover, the signal is divided into 2 lines. High output is fed into the amplifier of the full-range speaker. Low output is taken to the compressor channel and connects to the sub-bass amplifier. If you want the sub to run stereo, use both of the compressor's channels. But in the above diagram, according to the general experience, you should let the sub run in mono mode, which means using only one side of the crossover and a compressor put down the amplifier, combined 2 channels, and output the speaker. This will help to avoid the noise caused by resonance by 2 sub-channels if a different signal brings. There is one side left of the compressor for other uses, inserting into the mixer to adjust drum kicks for example.

On the mixer, you can take the signal from the aux out and put it into a single EQ, and use the monitor amplifier to power the monitor speakers on SK. If using two separate monitors, singer, and band, you can use one more aux 2, also via EQ and amplifier as aux 1.

2 effects then use the line aux send and aux return of the next 2 aux 3 and 4. Noise-gate then uses the insert phone jack ¼ ”(jack 6 millimeters) of each input of the mixer. This equipment is used to correct jazz drums for clear, neat sound.
