Auxiliary Sends

Definition

Auxiliary sends are outputs on an audio mixer that allow a portion of the audio signal from each channel to be sent to external processors or monitors. This feature is essential for creating effects like reverb or for routing audio to headphones or stage monitors without affecting the main mix. They offer flexibility in audio production by enabling sound engineers to manage multiple audio signals simultaneously.

5 Must Know Facts For Your Next Test

1. Auxiliary sends can be set up as either pre-fader or post-fader, affecting when the signal is sent relative to the fader position, which alters how the mix is balanced.
2. They are often used to create separate mixes for recording and monitoring, allowing performers to hear their own instruments and vocals without affecting the main output.
3. The number of auxiliary sends on a mixer can vary, typically ranging from two to multiple sends, depending on the complexity of the audio setup.
4. Using auxiliary sends effectively can enhance live sound quality and studio recordings by adding effects like delay and reverb independently from the main mix.
5. Sound engineers often utilize auxiliary sends in combination with equalization settings to ensure that effects do not muddy the overall sound when mixed back into the main output.

Review Questions

• How do auxiliary sends enhance the flexibility of an audio mix during live performances?
  • Auxiliary sends enhance flexibility by allowing sound engineers to create custom mixes for performers without altering the main output. This capability means each performer can have tailored audio levels for their monitors or headphones, enabling them to hear exactly what they need while performing. By routing signals through these sends, engineers can also apply effects separately, improving both individual performance experiences and overall sound quality.
• Discuss the differences between pre-fader and post-fader auxiliary sends and their practical implications in audio mixing.
  • Pre-fader auxiliary sends send signals before they reach the fader, meaning changes made to the fader do not affect the level sent to external processors. This is useful for creating consistent effects regardless of the main mix adjustments. On the other hand, post-fader sends send signals after passing through the fader, allowing for more integrated control where effects levels adjust automatically with changes in the main mix. Understanding these differences helps engineers make informed decisions based on their specific mixing needs.
• Evaluate how mastering techniques can be influenced by the use of auxiliary sends in both studio and live settings.
  • Mastering techniques can be significantly influenced by auxiliary sends, as they allow sound engineers to apply effects like compression or reverb without compromising the integrity of the primary mix. In a studio setting, this means that tracks can be blended together with precise control over dynamics and ambiance. In live environments, auxiliary sends enable real-time adjustments that cater to varying audience acoustics and performer needs. As a result, effective use of auxiliary sends contributes greatly to achieving a polished final product in both scenarios.

Send/Return: Send/return refers to a setup in audio mixing where a signal is sent from the mixer to an external effect processor and then returned back to the mixer for blending with the main mix.

Monitor Mix: A monitor mix is a specific audio mix created for performers, allowing them to hear what they need during a live performance, often using auxiliary sends to route different signals to stage monitors.
