Did you know that on every sound board there are two ways to send something out of an Aux Channel? These are called Pre-Fader aux send Post Fader aux send. Most people don’t know they have this option on their sound board or if they’ve seen it, they don’t know what it is for. So, what is the purpose of these two different send options? Well I’m glad you asked!!
Let’s start with the Pre-Fader send. A pre-Aux send delivers the audio signal out of the mixer after the gain, but before it passes through the channel fader. This option is most often used when sending a channel somewhere you don’t want the volume to change when you adjust the fader, aka adjusting the Main mix. You would find this most often on a monitor mix. If you have a monitor set up in a family room off your main area, you may not want the volume to fluctuate as it would in your main room. This is an easy option to accomplish this.
