Hello, and welcome to the Soundcraft Video Manual Series. Today, we’ll be quickly covering how to extend the number of auxes available on the Ui24r, allowing you additional busses for monitors or other applications. Let’s get started.
 You may have already noticed that in our Aux Sends screen, we have access to auxes 9 and 10, but our mixer only has 8 physical aux outputs. To utilize 9 and 10, we will need to patch them somewhere. Head over to the patching menu by going into the settings and selecting the patching tab. Select “HW Outs” on the left side of the grid and “Masters” should automatically select on the top side. Here we can see the routing for our main busses including the mains feed, our auxes, and the headphone feeds. The first thing you’ll notice is that auxes 9 and 10 do not have a patch. We’re free to patch them wherever we like, but our physical outputs on the right are all taken. A common approach is to utilize one of our headphone outputs for both auxes. 
First, let’s set up like we want aux 9 and 10 on separate headphone outputs. Make a patch from Aux 9 to this Headphone 1 left and right, then patch Aux 10 to Headphone 2 left and right. This will keep the auxes on their own outputs, and a TRS cable will be needed to keep them as mono balanced signals. Let’s set it up now like we want to use Aux 9 and 10 on one output, and still use headphones as usual on the 2nd output. Make a patch from Aux 9 to the Headphone 1 Left channel, and Aux 10 to the Headphone 1 Right channel. Also, re-patch one of our headphone feeds back into the Headphone 2 left and right. 
If you’re using auxes 9 and 10 together as a stereo pair on one of these outputs, then you can send the aux signal over a single TRS cable if the device you’re sending to has a single stereo input. However, you will need a special insert or stereo-splitting Y-cable if your receiving device has separate left and right mono inputs, or if you are running to separate monitors. This cable should be TRS on the end connecting to our mixer’s headphone output, but split into a dual connection that will have the TS from our mixer or left channel on one side and the RS or right channel on the other.
