Tenor (C3 to C5 / 123 Hz to 440 Hz):  The tenor range is known for its higher frequencies and the ability to reach high notes. Tenors often take center stage in vocal ensembles, infusing performances with emotional depth and captivating highs.

Alto (F3 to F5 / 175 Hz to 659 Hz): Altos, also called contraltos, occupy a comfortable mid-frequency zone. They inject richness and texture into choral harmonies and frequently shine in solo and group presentations.

Soprano (B3 to C6 / 262 Hz to 1047 Hz): Sopranos claim the highest vocal range, producing clear tones that effortlessly cut through musical arrangements.

EQs found on Mixers

Mixer EQ Settings for Vocals

The first step in achieving great vocal EQ using your mixer is to understand the EQ that you have at your disposal.

To start off, we assume that you are working with an analog mixer and that you are using the EQ that is built in to the mixer. This is also known as an onboard EQ.

EQ on Analog Mixers

Most analog mixers have multiple bands of EQ, typically ranging from 2 to 10 bands. These are part of the channel strip.

The most common configuration is a 3-band EQ, with controls for low, mid, and high frequencies.

Each EQ has a center frequency, which determines the frequency range that band will affect. There is also a control for boosting or cutting that band’s frequency range.

The low EQ control on an analog mixer is responsible for manipulating the low-frequency content of the audio signal. This control allows you to boost or cut the bass frequencies, typically ranging from around 20 Hz to 250 Hz.

The midrange EQ control on an analog mixer governs the frequencies that fall in the middle of the frequency spectrum, roughly between 250 Hz and 4000 Hz. This range is where a significant portion of the audio information resides, including the presence and character of vocals.

The highs EQ control manages the higher frequencies, typically spanning from around 4 kHz to 20 kHz. These frequencies contribute to the brightness, clarity, and detail of the audio.

For the exact frequency that the mixer EQ has been tuned to, you will need to refer to your mixer manufacturer’s manual.

High Pass Filter

A High Pass Filter is a special type of EQ found on mixers that allow you to boost or cut all the frequencies below a certain frequency.

This is normally used to remove unwanted low frequencies.

EQ on Digital Mixers

If you are using a digital mixer, it is likely that you will have a parametric EQ at your disposal.

This type of EQ allows you to control the center frequency that you wish to adjust as well as how much to boost and cut this frequency.

Key Frequency Ranges for Vocal EQ

Next, when it comes to achieving the best EQ settings for vocals in a mix, it’s essential to consider the key frequency ranges that affect the vocal sound. By targeting these frequency ranges, you can enhance vocal clarity and balance, resulting in a richer and more impactful vocal mix.

Here’s a helpful vocal EQ frequency chart to guide you on which frequencies to target:

Frequency Range Quality / Effect
100 Hz – 250 Hz Impact and warmth
500 Hz – 1 kHz Punchiness and presence
1 kHz – 4 kHz Clarity and brightness
4 kHz – 6 kHz Pronunciation and intelligibility
6 kHz – 8 kHz Sibilance and harshness

 

As you can see from the chart, each frequency range has a specific effect on vocal sound. Understanding how to identify and address common issues in each range can help you achieve the best EQ settings for vocals in a mix.

What this means is that if you find the the vocal lacks in any quality or effect, you should focus in on the corresponding frequency range and make adjustments to those frequencies using your available mixer EQ.

For example, if you find that a vocal lacks warmth and body, it means the frequencies between 100 Hz to 250 Hz are not prominent enough.

To make those frequencies more prominent, you can choose to use the mixer EQ to give the 100 Hz to 250 Hz range a boost, so that it will stand out from all the other frequencies.

Alternatively, to make that frequency range more prominent, you can lower or cut the other frequencies.

Or, if your vocals are lacking warmth and impact, boosting the 100 Hz – 250 Hz range can help. If vocals are lacking presence and punch, try boosting the 500 Hz – 1 kHz range. If vocals sound muddy or cluttered, cutting the 200 Hz – 500 Hz range can help cleanup the mix.

Keep in mind that these frequency ranges are not strict rules, and should be used as a starting point for EQ adjustments. Every vocal track is unique and may require different adjustments to achieve the best sound.

Troubleshooting Common Vocal EQ Issues

While optimizing vocal EQ can greatly enhance the quality and impact of vocal tracks, it can also pose certain challenges. Here are some common vocal EQ issues that may arise during the mixing process and some tips and techniques to help overcome them:

Issue Troubleshooting Tip
Muddiness in Vocals Reduce the low-mid frequencies to remove mud and enhance clarity. If necessary, use a high-pass filter to remove unwanted low-end rumble.
Unintelligibility in speech Try to give the 2 kHz to 4 kHz frequencies a slight boost to help bring out the consonants in the words. This will usually help with increasing the intelligibility.
Harshness in Vocals Reduce the high-mid and high frequencies to soften harsh sounding vocals. Alternatively, use a de-harsher plugin to specifically target and reduce harsh frequencies.

 

When troubleshooting vocal EQ issues, it’s important to start by making subtle adjustments. Small changes can make a big difference and can help you achieve a professional-quality vocal mix.

  • Trust your ears and make subtle adjustments
  • Reduce low-mid frequencies to remove muddiness
  • Reduce high-mid and high frequencies to reduce harshness

By being aware of common vocal EQ issues and having the necessary tools and techniques to address them, you can achieve a clean, polished vocal mix that enhances the overall quality of your music.

Quick EQ Cheats for Vocals

To oversimplify things, here are two quick settings that you can try for male and female vocals. Use this as a starting point to adjust for the voice that you are working with.

Male vocals

  • Boost the lows by +3dB
  • Cut the mids by -3dB
  • Boost the highs by +3dB

This setting will give the male voice more body while also increasing the clarity.

Female vocals

  • Cut the lows by -3dB
  • Leave the mids unchanged
  • Boost the highs by +3dB

This setting will give the female voice increased clarity and accentuate the voice’s individual character.

Some Additional Vocal EQ Tips Rules of Thumb

With the right vocal EQ settings for mixer, you can enhance the clarity, warmth, and overall quality of a vocal track. Here are some vocal EQ tips to bear in mind when you are working with vocals.

1. One of the most important vocal EQ tips is to start by cutting frequencies, rather than boosting them. This can help reduce any unwanted frequencies and create more space in the mix for the vocals. What this means is that, if you wish for a vocal to have greater clarity, instead of immediately boosting the high frequencies, you can try cutting the low frequencies instead. What this does is to clear away the low frequencies so that high frequencies are more prominent.

2. Be careful not to overuse EQ, as too much can lead to an unnatural sound when it been overly processed.

3. Another useful vocal EQ technique is to use a high-pass filter to remove low-frequency rumble or noise from the vocal track. To do this, simply set the high-pass filter to a frequency slightly lower than the lowest frequency present in the vocal track.

0

Welcome to our guide on audio compression! As avid audio engineers, we understand the importance of achieving optimal sound quality. In this article, we will explore the role of an audio compressor in audio engineering and production. We will explain what audio compression does, how it affects the dynamics of sound, and how it can improve overall audio quality.

Whether you’re a seasoned pro or a newbie to audio engineering, understanding audio compression is crucial in achieving a polished and professional sound. So, let’s dive in and unlock the secrets of audio compression!

Key Takeaways

  • An audio compressor is a tool used in audio engineering to control the dynamic range of sound.
  • Audio compression affects the loud and soft parts of sound, evening out inconsistent volume levels and preventing distortion.

Understanding Audio Compression

In the previous section, we discussed what an audio compressor does and its importance in audio engineering. In this section, we will take a closer look at the concept of audio compression and how it works.

Audio compression refers to the process of reducing the dynamic range of an audio signal. Dynamic range is the difference between the loudest and softest parts of a sound. Compression helps to control the dynamic range by reducing the volume of the loudest parts of the sound and amplifying the softest parts, resulting in a more even overall volume.

audio compression

The goal of audio compression is to achieve a consistent volume level throughout the audio signal. It can also help to prevent distortion or clipping, which can occur when the volume level exceeds the maximum level that a system can handle.

This involves a two step process. Firstly, it lowers any peaks that exceed a determined threshold and then it raises up the overall gain for the signal.

To achieve these results, an audio compressor applies a series of parameters to the audio signal. These include:

Parameter Function
Threshold The level at which the compressor begins to reduce the volume of the signal.
Ratio The degree to which the compressor reduces the volume above the threshold.
Attack The time it takes for the compressor to start reducing the volume once the threshold is reached.
Release The time it takes for the compressor to stop reducing the volume once the threshold is no longer exceeded.
Gain The level at which the output signal is boosted after compression.

 

By adjusting these parameters, an audio engineer can tailor the compression to the specific needs of the audio signal and create a more balanced and controlled sound.

Next, we will explore the broader role of an audio compressor in the field of audio processing.

The Role of an Audio Compressor in Audio Processing

As we have seen in previous sections, an audio compressor plays a critical role in controlling the dynamics of sound. However, its usage extends far beyond this basic principle, making it an essential tool in the field of audio processing. In this section, we will explore the various stages of audio production where an audio compressor is widely used.

The first stage where an audio compressor finds its application is in the recording process. When recording music, vocals, or any other sound source, variations in loudness can occur due to the performer’s technique or the particular instrument being played. An audio compressor can help to even out these inconsistencies, allowing for a more consistent recording.

Once the recording is completed, the next phase is mixing, where the various recorded tracks are combined into a single, coherent mix. Here again, an audio compressor is an invaluable tool. It can be used to tame rogue peaks and ensure that all of the elements of the mix are well-balanced and sit together harmoniously.

The final stage of audio processing is mastering. This is the process of finalizing the mix, ensuring that it is optimized for playback across all types of devices and listening environments. At this stage, an audio compressor is used to further refine the dynamics of the mix. It can help to create a cohesive sound that is consistent throughout the track and maximize the perceived loudness of the audio while avoiding distortion or excessive noise.

Overall, an audio compressor is a vital tool in the field of audio processing, and its usage extends across the entire audio production chain. From recording to mastering, understanding how to use an audio compressor effectively is essential for achieving professional and polished sound quality.

Controlling Audio Levels with an Audio Compressor

When it comes to audio engineering, controlling audio levels is key to achieving high-quality sound. An audio compressor is an essential tool that helps to regulate the volume of audio signals and maintain a consistent level throughout a recording or a live performance.

By compressing the dynamic range (the difference between the quietest and loudest parts of a track), an audio compressor can even out volume inconsistencies and prevent distortion or clipping. This makes sure that every part of the track can be heard clearly, without any sudden spikes that could damage speakers or cause discomfort to the listener.

audio compressor in use

There are a few things to keep in mind when using an audio compressor to control audio levels. The threshold determines the volume level at which the compressor starts to kick in. The ratio determines the degree of compression applied once the threshold is crossed. The attack and release settings control how quickly the compressor reacts to changes in volume, while the makeup gain is used to compensate for any volume loss due to compression.

It’s important to strike a balance between maintaining a consistent volume level and preserving the natural dynamics of the audio signal. Overcompression can result in a flat, lifeless sound, while improper ratio settings can cause pumping or breathing artifacts that are distracting to the listener.

With proper compression techniques, an audio compressor can be a powerful tool for controlling audio levels and achieving optimal sound quality.

Different Types of Audio Compressors

Now that we understand the concept of audio compression and its role in audio processing, let’s take a closer look at the different types of audio compressors available. Understanding the differences between various compressor types is important for achieving the desired sound quality in your audio engineering projects.

One of the primary distinctions between compressors is whether they are analog or digital. Analog compressors use analog circuits and components to process audio signals, while digital compressors use software algorithms to achieve compression.

Analog compressors are known for their warmth and character, and are often used in recording studios for their vintage or classic sound. They work by modifying the voltage of the audio signal, which affects its amplitude and creates compression. Some popular analog compressors include the SSL G Series, Teletronix LA-2A, and the Fairchild 670.

Digital compressors, on the other hand, offer more precise control over the compression process. They can often achieve a very transparent, clean sound. Many DAWs (Digital Audio Workstations) come with built-in digital compressors, such as the Waves SSL G-Master Buss Compressor, FabFilter Pro-C 2, or Universal Audio LA-2A plug-in.

Another way to categorize compressors is by their basic design. There are several compressor types that are commonly used in audio engineering:

Type Description
VCA (Voltage Controlled Amplifier) Uses a voltage-controlled amplifier to modify the gain of the audio signal.
Optical Uses a light source and photocell to adjust gain; often used for its smooth, musical sound.
FET (Field Effect Transistor) Similar to VCA compressors but uses a FET transistor instead of a voltage-controlled amplifier.
Tube Uses vacuum tubes to process the audio signal; often used for its warmth and vintage, analog sound.
Multi-band Divides the audio signal into separate frequency bands and applies compression to each band individually, allowing for more precise control over the sound.

 

Different Types of Audio Compressors

When selecting an audio compressor, it is important to consider the specific needs of the project and the desired sonic outcome. Each compressor type and model has its own strengths and weaknesses, and can be used to achieve different effects. Experimentation and experience are key to finding the right compressor for the job.

Setting Up an Audio Compressor for Optimal Performance

When it comes to setting up an audio compressor, there are several parameters that need to be considered.

It’s important to note that the optimal settings for these parameters will vary depending on the source material and the desired effect.

However, as a general rule, a slower attack time can be used to allow transients to come through, while a faster release time can help to avoid pumping and breathing artifacts.

It’s also worth considering the use of makeup gain, which can be used to compensate for the overall reduction in level caused by the compressor. However, it’s important to avoid excessive use of makeup gain, as this can lead to a distorted or unnatural sound.

Ultimately, the key to setting up an audio compressor for optimal performance is to experiment with different parameters and settings until the desired effect is achieved. Remember, there’s no one-size-fits-all approach to compression, so it’s important to take the time to find the settings that work best for your specific project.

audio compressor setup

Experimenting with different settings is the key to finding the optimal compression for your audio project.

Audio Compression Techniques for Enhancing Sound Quality

While basic compression techniques can help to control dynamic range and even out audio levels, advanced compression techniques can be employed to achieve more nuanced results.

These techniques include parallel compression, sidechain compression, and multiband compression.

Parallel compression involves blending a heavily compressed signal with an uncompressed signal to create a balance between the two. This technique is useful for achieving a thicker, more present sound without sacrificing dynamic range.

Technique Description
Sidechain compression Uses an external signal source to trigger compression on the main audio signal. This technique is often used to create a rhythmic pumping effect and to give space to other elements in the mix.
Multiband compression Used to compress specific frequency bands, rather than the entire signal. This technique is useful for addressing specific balance issues and ensuring that certain frequency ranges don’t overpower others.

 

While these advanced techniques can be powerful tools, they should be used judiciously and with a clear understanding of their intended effect. Overuse of compression can lead to a loss of dynamics and an overall reduction in sound quality.

On an analog mixer, you should raise the gain so that the incoming signal is at the 0 level. With digital mixers, the incoming signal should be raised up to -12 to 18 dB, depending on the mixer.
  4. Be mindful of distortion – if the sound starts to clip, reduce the gain slightly

It’s important to remember that the gain should be set to the lowest possible level that still achieves the desired volume. This helps to reduce background noise and distortion, resulting in clean and clear sound.

It’s also recommended to periodically check the gain levels throughout your audio production to ensure they remain consistent and properly adjusted.

how to adjust gain in audio mixer

Tip: If you’re adjusting the gain for a live performance, consider practicing before the event to ensure you have a good understanding of how to adjust the gain levels smoothly and efficiently.

Audio Mixer Gain Settings

There are several gain controls in an audio mixer that are responsible for adjusting the sound levels and maintaining the right balance throughout the production process. Here are the main types of gain controls you’ll find in a typical audio mixer:

Gain Control Purpose
Preamp Gain This control adjusts the signal level as it enters the mixer, ensuring that the input signal is strong enough to produce optimal sound quality.
Channel Gain This control adjusts the signal level for each channel, allowing you to bring individual instruments or vocals up or down in the mix.
Master Gain This control adjusts the overall sound level of the mix, allowing you to adjust the final output to the desired volume.

By adjusting these gain controls, you can adjust the individual sound levels of each channel, ensuring that the mix is balanced and that each instrument or vocal is heard at the right volume.

Note: It’s important to avoid overloading the gain controls, as this can cause distortion or unwanted noise in the mix. Always aim for the optimal sound level without going overboard.

Audio Mixer Gain Explained for Beginners

As a beginner in audio production, the concept of gain in an audio mixer can be overwhelming. Simply put, gain is the amount of amplification applied to an audio signal, allowing a microphone or other input source to be heard at the desired level.

Gain is an essential component of achieving optimal sound quality in your audio production. Without proper gain settings, your audio can sound distorted, too quiet, or too loud, affecting the overall quality of your project.

To adjust the gain in an audio mixer, simply locate the gain control knob for the channel or input source you want to adjust. By turning the knob clockwise, you increase the level of amplification, while turning it counterclockwise decreases it. It’s important to be careful not to turn the gain up too high, as this can lead to audio distortion.

When adjusting gain, it’s important to keep an ear out for any distortion or clipping. If you hear distortion, simply turn down the gain until the sound becomes clear and free of distortion.

It’s also crucial to pay attention to the level of the gain, as too little gain can result in a weak and quiet audio signal, while too much can result in distortion and clipping. Proper gain levels can be achieved by using a combination of preamp gain, channel gain, and master gain settings, as well as proper microphone placement and sound check before recording.

Remember, gain is a vital tool in achieving optimal sound quality in your audio production. By properly setting the gain in your audio mixer, you can ensure that your audio sounds clear, balanced, and professional.

Wave Shapes & Waveforms: Sine, Sawtooth, Square & Triangle

0

When it comes to describing sounds, it is common to refer to different types of wave shapes and waveforms. These two terms are often used interchangeably and common wave shapes include sine waves, sawtooth waves, square waves and triangle waves.

The wave shape describes the physical appearance of the wave form when plotted out on a graph. Each of these have their characteristic and distinctive sound.

Wave Shapes & Waveforms

Sine Wave

Wave Shapes & Waveforms Sine Wave

(Listen at a lower volume to protect your hearing)

Let’s start with the simplest wave shape – that of the sine wave.

The sine wave is made up of a smooth curve throughout the wave cycle. The energy of the wave rises continuously till it reaches its crest before falling to its trough and then eventually returning to tge center line.

A sine wave is also known as a pure tone and it is the easiest to identify as it sounds like a flute.

In the harmonic series, the fundamental frequency, second, third, fourth, fifth harmonics and so on, are all made up of sine waves. These simple sine waves combine together with different amplitudes to create more complex waveforms like sawtooth waves, square waves and triangle waves.

Triangle Wave

Triangle Wave

(Listen at a lower volume to protect your hearing)

The triangle wave gets its name from the shape of its waveform.

Triangle waves have a brighter sound compared to sine wave. Shape-wise, it looks like an angular-version of sine wave with the amplitude of the wave rising before sharply falling. The rise and fall of the amplitude is symmetrical This results in a sound that has some of the characteristics of a sine wave but with an edgier sound.

The sound of a recorder being played breathily produces a waveform similar to a triangle wave.

Sawtooth Wave

Sawtooth Wave

(Listen at a lower volume to protect your hearing)

The sawtooth wave is named because it looks more jagged and is skewed to one side – just like the teeth on the blade of a saw.

This sound of a sawtooth wave is edgy, buzzy and almost distorted. This is a reflection of the richer harmonic content of this type of wave.

Examples of instruments that produce sawtooth waves are brass instruments like trumpets and stringed instruments being bowed.

When a violin is bowed, the sound is generated when the bow “catches” the string by friction, pulls it a distance before releasing it. This action takes place repeatedly as the bow is dragged across the string, giving the violin a slightly buzzing sound.

Square Wave

Square Wave

(Listen at a lower volume to protect your hearing)

A square wave is created by combining the odd harmonics, in other words, the 1st, 3rd, 5th, 7th harmonics and so on, in a specific proportion. This creates a shape that resembles a square. It has quite a harsh and edgy tone.

The sound of a square wave is similar to that of a clarinet. It also sounds like 8-bit computer music from the past.

What Are Harmonics & Overtones?

0

When it comes to sound, you may be wondering what are harmonics and overtones and why are they even important?

When someone you know calls you up on the phone, are you able to tell who the person is? You are likely to because – in layman’s terms – you can recognise the person’s voice. There is something unique that makes a person’s voice sound like his or her voice.

Harmonics and Overtones Give a Sound its Character

Harmonics Give a Sound its Character

In terms of sound theory, it is the harmonics that give his or her voice its unique characteristic. This is also true for other sounds.

Without the harmonics and overtones, every sound would be a simple sine wave.

Harmonics and overtones add sonic characters to a sound, whether it be a voice or an instrument.

Let’s take a closer look at what exactly harmonics and overtones are.

When you hear the piano place a note like middle C, what you are actually hearing are many different notes ringing out together at the same time. All these notes combine to create the sound that we characteristically know as that of a piano.

These different notes are called harmonics.

Fundamental Frequency and Harmonics

Harmonics and Overtones Give a Sound its Character

One of these notes is the loudest. This is called the fundamental wave or fundamental frequency. This is the main note that we will associate with the sound.

For example, when middle C is played on a piano, the fundamental frequency is 261 Hz, which is the frequency of the middle C note.

The rest of the notes are softer than the fundamental frequency and pile on top of the fundamental frequency to create the sound of a piano. This is how our ears can distinguish between a C with frequency of 261 Hz played on a piano versus a C of 261 Hz played on a guitar.

There are different factors that affect how the harmonics are created. These include factors such as the size of the instrument, the materials used, how the note is struck and so on.

Calculating the Harmonic Series

Nonetheless, these harmonics follow the laws of physics and can be calculated. They are multiples of the fundamental frequency.

For example, if you were to play the note A which vibrates at the frequency of 440 Hz, the harmonics can be calculated by multiplying 440 by 1, 2, 3, 4, 5, and so on.

Here is a worked example.

440 Hz x 1 = 440 Hz, First harmonic, or better known as the fundamental frequency.

440 Hz x 2 = 880 Hz, Second harmonic

440 Hz x 3 = 1,320 Hz, Third harmonic

440 Hz x 4 = 1,760 Hz, Fourth harmonic

440 Hz x 5 = 2,200 Hz, Fifth harmonic

440 Hz x 6 = 2,640 Hz, Sixth harmonic

440 Hz x 7 = 3,080 Hz, Seventh harmonic

440 Hz x 8 = 3,520 Hz, Eighth harmonic

and so on …

Normally, you would calculate the harmonic series up to 20,000 Hz, which is the limit of the human hearing range.

As the different harmonics combine together, both constructive and destructive interference takes place. This results in the summing and cancelling, giving the combined wave a particular characteristic shape.

The waveform created by each instrument or sound source is what allows our ears to distinguish one sound from another.

Overtones are similar to harmonics and within the musical context, the term is often used interchangeably even though there are some differences.

Next, you might want to learn more about different types of wave shapes and waveforms.

What Is A Sound System?

0

Audio engineers work with sound systems. But what exactly are sound systems? Is the sound system the same as the arrays of buttons and knobs found on in front of the audio engineer at a mixing desk? Or is it the speakers?

The Purpose of a Sound System

Let’s start at the beginning.

The purpose of a sound system is to reproduce a sound source.

In a live performance setting, sounds originate from a sound source. This is normally acoustic in nature.

Examples of sound sources include the human voice, a guitar string being plucked or a drum being struck. These sound sources produce sound waves that travel through the air to reach the listeners ears.

This is all well and good when you just have a few listeners who can hear the waves directly from the source. However, what happens when there are many people and they are all clamouring to hear the sound source?

One option would be for the sound source to increase its amplitude. This could mean that a person talking needs to raise his or her voice. Or the guitarist needs to strum even harder to get the strings to vibrate at a larger amplitude.

However, even then, this eventually reaches a limit.

That’s where a sound system comes in.

The purpose of a sound system, in a live sound context, is to reproduce and amplify the sound source or sources.

It takes acoustic sound waves, converts it into electrical signals that can then be amplified, before converting them back into acoustic sound waves to reach the ears of listeners.

Parts of a Sound System

Any sound system, no matter how simple or complex, can be broken up into three sections.

Input Section

The input section is where the acoustic sound get captured and gets converted into electrical signals. This is most commonly done with a microphone.

A microphone picks up the incoming sound waves and converts them into an electrical signal. This electrical signal gets sent to the next section of the sound system.

Mixing Section

What is a sound system - Mixing Section

The mixing section of a sound system is where the incoming electrical signals can be adjusted, processed and combined.

If the incoming electrical sound signal is too weak, it can be adjusted by raising up its level.

The signal can also be processed. For example, using an equalizer, you can boost or cut certain frequencies that are present in the signal.

Lastly, the mixing section is where you can combine different incoming signals and send them to different outputs where they are required.

Output Section

The output section is where electrical signals get converted back into acoustic sound waves.

But before it can do so, the electrical signals need to be amplified. This basically entails stepping up the power voltage of the signal so that it is more powerful than before. This is done using a power amplifier, a piece of equipment that steps up the voltage of the signal.

Once the signal has been amplified, it is then sent to the loudspeakers, where it is converted from electrical signals back into acoustic sound waves.

Signal Flow Through the Sound System

This is how sound journeys through a sound system. It first gets captured at the input section, then it is sent to the mixing section before finally being converted back to sound waves.

This is the signal flow through a sound system.

Sound System Model

A simple sound system may just have one piece of equipment at the input section and then it could pass on to the mixer, through an amplifier and out from one loudspeaker.

Signal Flow Through the Sound System

In larger, more complex sound systems, there could be tens of microphones on a stage. All the inputs from these microphones could then be sent to a mixing desk some where in the middle of a hall where all the inputs are mixed together and processed. Then the mixed signal could then be sent out to a rack of power amplifiers and to a stack of loudspeakers hanging from the ceiling at the side of the stage.

Nonetheless, whether it is a simple one-microphone system or a complex concert setup, both of these sound systems can be broken up and understood using the same input, mixing and output model.
