Pre and Post fade Aux Mixes

As most of our communities have switched over to streaming in the last few weeks, we wanted to focus on bringing you tips on streaming! Lambda want to make sure you are confident in your stream and give you other options as you look to adjust your setup to be more effective.

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.

The other send option is Post-Fader. A post aux send delivers the signal out of the mixer after it’s gone through the fader. So, when you move the volume fader, the aux send volume is equally changed. The post-fader option is most often used on a send that you want to “follow” the same mix you are sending to the main house speakers. You can often find this type of aux feeding a lobby speaker or a streaming mix.

Now you may be wondering if you have your aux send set to the correct option for streaming your even this week. You can find this as a setting on your console. You can see from the picture what it looks like, but if you are having trouble finding it you can check your manual or contact Lambda anytime! We’d love to help give you more information on the aux send function.
