Auxiliary sends

Definition

Auxiliary sends are routing options in audio mixing that allow a portion of a signal to be sent to an external processor or effect, like reverb or delay, while the main signal continues to play through the primary output. This feature enables sound engineers to create effects on specific audio channels without altering the original sound, providing flexibility in mixing. By using auxiliary sends, different levels of effects can be applied across various channels independently, enhancing the overall sound design.

5 Must Know Facts For Your Next Test

1. Auxiliary sends are commonly used in live sound reinforcement and studio recording environments to apply effects without affecting the original signal.
2. Each channel strip on a mixing console usually has its own auxiliary send controls, allowing for independent adjustment of levels sent to effects processors.
3. Using auxiliary sends can help manage feedback loops by allowing a controlled amount of signal to be processed separately from the main mix.
4. Auxiliary sends can be configured as pre-fader or post-fader; pre-fader sends send the signal before the fader level is adjusted, while post-fader sends send it after adjustments.
5. In digital audio workstations (DAWs), auxiliary sends are typically implemented as tracks where effects can be applied and mixed back into the final output.

Review Questions

• How do auxiliary sends improve the mixing process when working with multiple audio channels?
  • Auxiliary sends enhance the mixing process by allowing sound engineers to send a portion of an audio signal to effects processors independently of the main mix. This means that different channels can have varying amounts of effects applied without altering their original sound. By adjusting each channel's send level individually, engineers can create unique soundscapes that blend seamlessly in the final output.
• Discuss the difference between pre-fader and post-fader auxiliary sends and their applications in audio mixing.
  • Pre-fader auxiliary sends route the audio signal before it reaches the fader, allowing for consistent effect levels regardless of how the fader is adjusted. This is useful for creating monitor mixes where performers need consistent sound levels. In contrast, post-fader sends route the signal after the fader, meaning adjustments to the fader will affect both the main output and the level sent to effects. This setup is often used for recording and mixing where you want effects to follow the changes made in the overall mix.
• Evaluate the impact of using auxiliary sends on live performance setups versus studio recordings.
  • In live performance setups, auxiliary sends are crucial for managing monitor mixes and ensuring performers receive the right balance of their own instruments along with effects without altering the front-of-house mix. Conversely, in studio recordings, they provide flexibility in applying effects during mixing sessions without compromising individual track integrity. The use of auxiliary sends allows engineers in both contexts to manipulate sound creatively while maintaining control over each element's contribution to the overall mix.
