Using Pink Noise to Ring Out Your XR18: A Comprehensive Guide

With the arrival of digital mixers, handling audio tasks has become easier than ever. One of those tasks is using pink noise to ring out a system – essentially just figuring out the best frequency response for your setup.

Let's start by understanding what pink noise is. Pink noise is a random noise where every octave carries equal energy – a so-called '1/f noise' spectrum. This makes it ideal for testing the frequency response of audio systems.

Now, let's delve into how to use pink noise to ring out the XR18.

1. Install relevant apps: Before starting, ensure you have the XR18's X Air Edit app downloaded on your computer, smartphone, or tablet. You will need this app to access the mixer's controls and to ring out your setup.

   
   



2. Connect the XR18: Set up the XR18 mixer and connect it to your sound system. Ensure it is connected to a Wi-Fi network and that you can access the X Air Edit application on your device.

   
   



3. Generate Pink Noise: Within the X Air Edit app, select any input channel (or channels) you want to ring out with pink noise. Head to the input channel Preamp tab, and click on the 'Pink Noise' button to activate pink noise generation. Adjust the gain slider so that the noise is audible but not too loud.

   
   

1. Utilize the built-in RTA: Now, utilizing the built-in Real-Time Analyzer (RTA), you'll be able to see the live frequency response of your speakers. You can access this feature in the XR18 by opening the Main LR or any Bus tab, clicking the EQ screen, and then tapping the RTA tab.

   
   



2. Adjust EQ: As you watch the RTA display, listen carefully for any frequencies that are causing excessive feedback, ringing, or uneven response. Use the parametric EQ option in the XR18 to adjust those frequencies accordingly. Make sure to keep some headroom so the system doesn't get overloaded or damaged.

   
   



3. Safeguard with a Graphic EQ: To avoid feedback frequencies, you can also apply a Graphic EQ to the Main LR or a Bus output. In the EQ tab, simply click on the 'GEQ' button to access this. You can adjust specific frequencies down to prevent potential feedback issues.

   
   

1. Repeat the process: If you have multiple input channels, speakers, or areas to cover, repeat the process for each one until you achieve the desired frequency response and a well-balanced sound in your venue.

Using pink noise to ring out the XR18 helps ensure that your live performances will have a smooth, accurate sound. By following these steps, you'll be able to calibrate your system to achieve optimal output, minimizing feedback and ensuring the best possible experience for your audience.
