Auxiliary Sends

Definition

Auxiliary sends are signal routing pathways used in audio mixing that allow you to send a portion of an audio signal to an external processor or effect while keeping the original signal intact. This technique is essential for creating effects like reverb or delay without altering the original track. It enhances the mixing process by enabling multiple tracks to share the same effect, adding depth and richness to the overall sound.

5 Must Know Facts For Your Next Test

1. Auxiliary sends can be set to pre-fader or post-fader; pre-fader sends are useful for maintaining effect levels regardless of the track's volume changes.
2. Using auxiliary sends allows for more efficient use of processing resources by letting multiple tracks utilize the same effect instance.
3. They can help create a more cohesive sound by allowing different instruments or vocals to share common effects like reverb, giving the mix a sense of space.
4. Auxiliary sends are typically adjusted using a knob on the mixing console, which controls how much of the signal is sent to the effects unit.
5. Understanding how to effectively use auxiliary sends is crucial for achieving a polished and professional-sounding mix.

Review Questions

• How do auxiliary sends differ from direct channel outputs in a mixing context?
  • Auxiliary sends differ from direct channel outputs as they allow you to route a portion of the audio signal to effects processors while maintaining the original unaltered signal in the mix. Direct outputs, on the other hand, send the full signal directly to recording devices or other destinations without any processing. This distinction is important because auxiliary sends enable creative effects processing and control over how those effects blend with the main mix.
• In what ways can using pre-fader and post-fader auxiliary sends impact the final sound of a mix?
  • Using pre-fader auxiliary sends allows the effects level to remain constant even if the main track's volume is adjusted, which can be beneficial for consistent effect presence. Post-fader sends tie the effects level to the track's volume; as you lower or raise the track’s fader, the level of the effects will also change. This choice can significantly impact how effects blend into the mix and how they interact with dynamics across different parts of a song.
• Evaluate how mastering engineers might utilize auxiliary sends differently than mixing engineers during their processes.
  • Mastering engineers may use auxiliary sends primarily for applying global effects across an entire mix, such as overall reverb or equalization adjustments. Unlike mixing engineers who focus on individual tracks and their relationships within a song, mastering engineers look at how all elements come together in a final product. Therefore, they might employ auxiliary sends to add subtle enhancements that polish the overall sound while ensuring cohesiveness across various playback systems.
