This allows for flexibility in shaping the overall mix and gives the engineer control over individual channel levels.
Aux sends operate at line level, which is a higher signal level than mic level. Line level signals are stronger and relatively noise-free, making them suitable for routing to external devices. Mic level signals, on the other hand, are much weaker and require preamps to boost their levels.
Understanding the purpose of aux sends is crucial for audio engineers, as it opens up a world of possibilities for shaping the sound and delivering optimal audio experiences.
Differentiating Between Line Level And Mic Level Signals
Line level and mic level signals are two common types of audio signals used in audio systems. Understanding the difference between these signals is crucial for properly setting up and utilizing aux sends in audio mixers and consoles.
Mic level signals are low-level signals generated by microphones. They typically have a lower voltage and require preamplification to bring them to a usable level. Mic level signals are more susceptible to noise and interference and are commonly used for capturing audio from sources such as vocals and instruments.
Line level signals, on the other hand, are higher-level signals that do not require preamplification. They are generated by line-level sources like CD players, keyboards, and audio interfaces. Line level signals have a higher voltage and are less susceptible to noise and interference.
Understanding the difference between line level and mic level signals is important because aux sends are typically designed to work with line level signals. When setting up aux sends, it is essential to ensure that the signal being sent from the aux send is at line level to maintain optimum audio quality and prevent distortion. Additionally, understanding the level requirements of different devices connected to the aux send can help in proper signal routing and designing an effective audio system.
The Function And Importance Of Aux Sends In Sound Reinforcement
Aux sends play a crucial role in sound reinforcement systems by providing additional routing and control options for audio signals. Essentially, they are parallel mixers that allow you to create independent mixes and send them to different destinations, such as stage monitors or effects units.
One of the primary functions of aux sends is to create monitor mixes for performers on stage. This enables them to hear a tailored mix of the audio sources they need, making it easier for them to perform in sync with the rest of the band or team. In larger setups, aux sends can also be used to create submixes for specific zones or speaker clusters, allowing for greater control over the sound distribution across a venue.
The importance of aux sends lies in their ability to provide flexibility and customization in a sound reinforcement setup. By being able to route signals independently, sound engineers can fine-tune audio levels, apply effects as desired, and adjust monitor mixes to cater to specific needs. This ensures that performers can hear themselves clearly and that the audience receives a high-quality sound experience.

Aux sends are a fundamental component of audio mixers and consoles, allowing engineers to route specific audio signals to external devices or processes. Understanding the different types of aux sends available can greatly enhance your flexibility and creative control over your sound reinforcement system.
The most common types of aux sends found in audio mixers and consoles are pre-fader and post-fader sends. Pre-fader sends operate independently of the channel fader, sending a set level of signal regardless of the channel’s volume level. This is ideal for sending signals to external effects processors or recording devices, ensuring a consistent level of effect or recording regardless of changes to the channel’s overall output.
Post-fader sends, on the other hand, are affected by the channel fader’s position. As you adjust the channel’s volume level, the post-fader send will follow suit, making it suitable for creating monitor mixes or sending signals to stage monitors. This allows musicians to have customized mixes in their monitor systems that accurately represent the overall mix.
Some mixers or consoles also offer additional aux sends, such as pre or post-EQ sends. These provide further control over the audio signal by allowing you to send signals before or after equalization adjustments.
By understanding the different types of aux sends and their applications, you can optimize your audio system’s performance by tailoring your sound to specific needs.
How To Set Up And Adjust Aux Send Levels For Different Applications
