Basic Concepts of Sound

Understanding the basic concepts of sound enhances your ability to mix audio effectively.

When you’re connecting an equalizer and compressor to a mixer, it’s crucial to have a grasp on these foundational elements.

Frequency Response:

  • This term describes how a device like a mixer or speaker reproduces various frequencies.
  • Devices exhibit a range, such as 20 Hz to 20 kHz, which is the typical range of human hearing.

Noise:

  • Unwanted sound that interferes with the signal.
  • The goal in audio setup is to minimize it to ensure clarity.

Signal:

  • The audio signal is the electrical representation of sound.
  • It travels through your equipment, carrying the information of your audio.

Gain:

  • Refers to the increase in a signal’s power or amplitude.
  • Adjusting gain levels is critical to achieving the correct balance without distortion.

Power:

  • The amount of electrical energy supplied to the system.
  • Sufficient power is necessary for clear and loud reproduction but too much can cause damage.

When setting up an equalizer and compressor, understand that your gain settings will influence the signal’s power and noise levels, potentially impacting the frequency response of the final sound.

Your mixer is at the heart of this process, manipulating these sound characteristics to create the desired output.

Mixing Console Overview

When you’re eager to create the perfect mix, your mixing console is at the heart of piecing together the sound you envision. Familiarizing yourself with its layout and functionality is key.

  • Channels: Here’s where each instrument or sound source gets its designated spot. You’ll find a channel strip for each input on your mixer, often ranging from a few channels to dozens on larger boards.
  • Signal Path: As you maneuver through a channel, the signal path starts at the input and travels through various controls such as EQ, and aux sends, before reaching the fader at the bottom.
  • Mix: Your ultimate goal on the mixing console is to balance and blend all input channels into a harmonious mix. Each channel contributes to the overall sound that comes out of the mixer’s main output.
  • Faders: These linear controls allow you to adjust the volume of each channel. Moving a fader up increases the signal volume, while moving it down decreases it.
  • Aux Knobs: Situated above the faders, aux (auxiliary) knobs give you the power to route a portion of the signal to external effects or monitor mixes. They’re invaluable for adding reverb, delay, or sending a custom mix to a performer’s stage monitor.

Your mixing console may vary in complexity from others, but these elements are universal across all boards. Get comfortable with them, and you’ll be shaping soundscapes with confidence in no time.

Microphones and Inputs

Before jumping into the connectivity of your equalizer and compressor to the mixer, it’s crucial to understand the types of microphones available and the input connections they require. Each microphone type and connector plays a significant role in the quality and control of sound entering your mixer.

Microphone Types

Dynamic microphones and condenser microphones are the primary types you’ll encounter.

Dynamic mics are known for their durability and ability to handle high sound pressure levels, making them suitable for loud sources like guitar amplifiers and drums.

Condenser mics, on the other hand, require phantom power (+48V), provided through the mixer or an external source, and are more sensitive, perfectly capturing the nuances in vocal performances.

  • Dynamic Microphones: Ideal for live performances and loud instruments
  • Condenser Microphones: Best for studio recordings and capturing vocal subtleties

Input Connections

Your mixer accommodates various input connectors.

The XLR connectors are the most common for microphone inputs, providing a balanced connection that minimizes noise and interference. Ensure that your mic cables are properly connected to these XLR inputs for optimal sound quality.

TRS (Tip, Ring, Sleeve) connectors are another option for line-level devices and can also support balanced audio.

Gain knobs on each channel allow you to adjust the input level, ensuring your signals are neither too low nor peaking.

For effects such as your equalizer and compressor, insert cables (typically a TRS-to-dual TS cable) are used in the insert jacks.

This setup enables you to modify the signal of individual channels with your outboard gear:

  • Insert Send: Directs the pre-fader signal from the channel to your processor (compressor/EQ)
  • Insert Return: Brings the processed signal back to the channel strip

Utilizing the correct cables and input types is paramount in crafting a pristine and noise-free audio environment for your live or studio mixing sessions.

Always opt for balanced cables for microphone connections to avoid any unexpected noise or hum.

Be cautious when using unbalanced cables, as they are more susceptible to noise and are best used for shorter runs or in environments with minimal interference.

Signal Processing

Audio Cables Connected to Audio Device

Before you begin connecting your eq and compressors, it’s important to understand that signal processing can greatly enhance your mix. It allows you to manage the dynamic range and apply specific effects to your output.

Dynamic Range Control

Compressors and limiters are essential for controlling the dynamic range of your audio. They ensure that your signal maintains a consistent level by compressing peaks and boosting quieter parts.

  • Compression: This reduces the volume of loud sounds that exceed a certain threshold, maintaining a more even signal level.
  • Limiter: A more extreme form of compression, a limiter restricts the signal from going past a set ceiling, avoiding any potential distortion.

Effects and EQ

Your mixer’s signal can be enhanced or altered with various effects and by using an eq.

  • Graphic Equalizer: Tailor the balance of frequencies to improve sound quality or adjust for room acoustics.
  • Reverb Unit: Adds depth and space to your mix, simulating the sound of different environments.
  • Effects Processor: Can be used for multiple effects, such as delay or chorus, to add richness and texture.

Inserts and Aux Sends are typically used to connect these devices to your mixer:

  • Inserts: These are for inline effects such as compression and equalization, where the processor needs to affect the entire signal.
    • Use a TRS Y cable—the tip goes to the input of the processor, and the ring goes back to the mixer.
    • The output of the compressor connects directly into the input of the eq.
  • Aux Sends: Best for effects like reverb and other time-based processors that you want to mix with the original signal.
    • Choose an Aux Send output on your mixer and connect it to the input of your reverb unit or effects processor.
    • The unit’s output then goes to the mixer’s return channel or back to an unused channel.

Monitoring and Output

In the context of connecting your equalizer and compressor to a mixer, understanding how to properly manage monitor mixing and the main output is crucial for achieving the best sound quality for both live performances and studio recordings.

Monitor Mixing

To adjust your monitor mix, which is what the performers hear on stage through monitor speakers, follow these steps:

  • Use an auxiliary send on your mixer to route the mix to the monitor speakers.
  • Equalize this mix specifically for the stage without affecting the main mix.
  • Apply compression subtly to avoid feedback and maintain a consistent level in the monitors.

Main Output

The main output deals with what the audience hears through the loudspeakers, also known as the mains. Here’s what to focus on:

  • Ensure your main mix goes through the master output with the proper levels.
  • Connect the main mix inserts to route through your compressor and equalizer for enhanced control over dynamics and tone.
  • Use a Y-insert cable to connect your equalizer and compressor with the mixer, which can be seen in practical examples from Sweetwater and AudioRecording.me.

Live Sound Reinforcement

When setting up for live sound, your goal is to ensure clarity and balance across the entire frequency spectrum. To achieve this, you’ll need to connect your equalizer (EQ) and compressor effectively within your PA system.

Connecting Your Equalizer:

  • Your EQ’s primary role is to shape the tonal balance of your sound. It should be connected between the mixer’s output and the power amplifier.
  • If you’re using a graphic EQ, consider inserting it across the main output for broad control.

Setting Up Your Compressor:

  • Compressors are vital for managing dynamics and preventing signal peaks that could lead to distortion.
  • Connect the compressor to the channel insert points on your mixer using insert cables. This allows the compressor to act directly on individual channels.

Integrating the Crossover:

  • If your PA system includes subs and tops, the crossover becomes crucial. It splits the frequency range, directing low frequencies to the subs and highs to the tops.
  • Connect the mixer’s output to the crossover’s input, and then from the crossover’s outputs to the power amplifiers.

Loudspeakers Placement:

  • Arrange your loudspeakers so there’s a spread of sound throughout the venue.
  • Pay attention to the mains; ensure they are not obstructed and are at ear level for optimum coverage.

Recording and Production

In the realm of recording and production, understanding how to connect your equalizer and compressor to your mixer is fundamental. This will ensure that you have control over the audio’s dynamics and tone during both the recording and post-production phases.

Multitrack Recording

For multitrack recording, you’ll want to start by connecting your mics to the mixer. Multitrack recorders or DAWs (Digital Audio Workstations) allow you to record each instrument on separate tracks. Using an equalizer and compressor during this stage requires careful setting of levels:

  • Insert a compressor into the signal path to control dynamics. Use an insert cable to connect the send on the mixer to the input on the compressor and then return it from the compressor’s output back to the mixer’s return.
  • Apply an equalizer to shape the tone of each track, ensuring the instrument sits well in the mix. EQ can be added in a similar fashion to the compressor, by using another insert cable.

Mixdown and Mastering

When moving on to mixdown and mastering, your mix should be refined, with each track’s volume, EQ, and compression adjusted to work cohesively:

  • Iterate your mix on the mixer, tweaking levels, panning, and applying additional EQ or compression as needed.
  • For mastering, you might switch to a stereo compressor and equalizer to enhance the overall sound of your mix. This is your last chance to fine-tune the dynamics and frequency balance before distribution.

How to Connect an Equalizer and Compressor to a Mixer – Auxiliary Sends and Returns

When connecting an equalizer and compressor to a mixer, understanding auxiliary sends and returns is crucial. The aux send originates from individual channels on your mixer, allowing you to route audio to external effects like compressors or EQs.

There are two types of aux sends:

  • Pre-fader: The signal is sent before the channel fader, which means the send level is not affected by the fader position. This is ideal for monitor mixes.
  • Post-fader: The signal is sent after the channel fader, ensuring that any changes to the fader level will also affect the signal sent to the processor—used primarily when you want effects like reverb to reflect the mix’s fader movements.

Connecting Aux Sends:

  1. Use a cable to connect from the aux out jack on the mixer to the input of your effect unit, such as a compressor.
  2. Adjust the aux send control to set the amount of signal you want to send from that channel to the external effect.

Utilizing Returns:

  • Connect the output of your effect unit back to an available channel or return input on the mixer.
  • If your mixer has a dedicated return section, use this to balance the processed signal back into your mix.
