Sound System Mixer: What It Does and Its Key Features
Before you buy an audio mixer, learn what it does and how gain, channel EQ and other controls work, from live shows to recording studios and broadcast.
A sound system is an essential part of any event, so it's no surprise that each of its supporting components is in demand. One of those components is the sound system mixer. Before you buy one, you should know what the device does. Read on for the details.
What an Audio Mixer Does
An audio mixer is a device that blends sounds together, which is why it is often called a mixing console. There are at least two types of audio mixer: analog and digital. Once a mixer is in use, the sound that comes out is noticeably better and more harmonious.
These devices come in many types and at many prices. You need to learn each product in detail before buying. It is a bit of a hassle, but it is essential because audio mixers vary so much.
So when is an audio mixer used? Whenever there is a live show, whether off air or on air. Besides recording studios, mixers are always found in radio and television studios and in film post-production. The audio mixer is the meeting point for every microphone and instrument, so that everything sounds aligned and cohesive.
With a sound system mixer, you can set each sound level to your taste. As a result, the balance can be shaped so that it is pleasing to the ear. Once everything is set, an amplifier boosts the sound. Remember that every device in the chain supports the others.
Common Audio Mixer Features
There are at least six useful sections, or features, on an audio mixer. They include gain, channel EQ, fixed EQ, sweepable EQ and various other settings. Gain is also known as trim. It always sits at the top because its function is so important.
Trim sets how sensitive the input should be. Inputs vary and can be a mic signal or a line signal such as a keyboard or tape deck. Channel EQ is the equalizer. Sound engineers usually change the sound through this section.
The basic controls of this part of a sound system mixer are expressed as low and high. Then there is adding and reducing, known as boost or cut. Some equalizers are far more complex, with four bands and a parametric function. Whatever the type of equalizer, the goal is the same: finding the best sound.
The other sections not covered here share the same purpose, which is to produce good sound output. This basic explanation of the audio mixer is much needed. Look into the different types of mixers so you don't buy the wrong one. You can find interesting products at Goshen Swara Indonesia, and their prices are fairly affordable and easy on the wallet.
