How to Set Up Pink Noise on the Behringer WING for Room Tuning

Room tuning is an essential part of live sound reinforcement. Whether you’re in a church, auditorium, or any live event space, ensuring the PA system delivers clear and even audio throughout the room is crucial. One powerful tool used in room tuning is Pink Noise. In this article, we’ll break down how to send Pink Noise from your Behringer WING digital mixer, which can then be used with analysis software and a reference microphone to tune your PA system.

We’ll walk step-by-step through:

What is Pink Noise and Why Use It?

Pink noise is a type of test signal used in audio engineering and acoustics. It sounds like static, but it’s more than just random noise.

Pink noise contains equal energy per octave, making it ideal for room tuning. When passed through a PA system and captured with a measurement microphone and RTA (Real-Time Analyzer) software, it helps reveal frequency spikes or dips caused by room acoustics, speaker placement, or EQ settings.

Unlike white noise, which is bright and harsh, pink noise is spectrally balanced and closer to how humans perceive tonal balance.

🎯 TIP: The goal of room tuning is to achieve a flat frequency response where no frequencies are exaggerated or lacking. Pink noise helps you visualize and correct these imbalances.

Step-By-Step Setup: Sending Pink Noise on the Behringer WING

To work with pink noise, you need to use the oscillator built into your Behringer WING mixer. Here’s the complete step-by-step process.

🔧 Step 1: Choose an Unused Channel

You’ll want an empty/available input channel on the Behringer WING to route pink noise to.

Examine your channels. Locate one you’re not actively using. (For example, channel A2.)
Select that channel by tapping it.

🎚 Step 2: Access Routing Settings

Now, let’s route an internal oscillator as the input source for your selected channel.

Press the [Routing] button on your WING.
Navigate to Sources (found on the touchscreen).
You’ll see options like “Local In” as default.
Hit the dropdown menu and scroll to find Oscillator.
Select Oscillator 2. (There are 2 independent oscillators available on the WING.)

🔊 Step 3: Configure Oscillator Settings

With Oscillator 2 selected, configure it accordingly:

On the bottom right of the screen, you’ll see oscillator type options:
- Sine wave (you can choose a specific frequency)
- Pink noise
- White noise
Choose Pink Noise.
- This tells the oscillator what type of signal to generate.
Optionally, select Mono or Stereo depending on how you want to measure and route the test signal.

🔌 Step 4: Patch Oscillator to Your Channel

Now, make sure your selected channel (e.g., A2) is receiving the pink noise signal.

Go to the Home screen and select the channel in question.
Tap the Patch button (bottom of the channel view).
From the list of patchable sources, select Oscillator 2.
Confirm that OSC2 now appears in the input strip of your channel.

✅ You should now see signal activity on the channel meter.

📢 Step 5: Unmute and Monitor Output

With the patching complete, it’s time to hear—or use—the pink noise.

Unmute the channel.
Bring up the fader to an audible level.
Slowly monitor the output through your house speakers or test route.

You’ll hear a static-like sound — that’s your pink noise!

🔊 WARNING: Pink noise is a full-spectrum signal and can be loud. Start with volume down and increase gradually to prevent damaging speakers or ears.

🔄 What’s Next: Using Pink Noise to Tune Your Room

While this video and guide focus strictly on routing the pink noise, here’s a quick overview of what to do next:

Use a Measurement Microphone placed at listening positions.
Connect the mic to a laptop with audio analysis software such as Room EQ Wizard (REW), Smaart, or TrueRTA.
The software will display the frequency response of your room.
Use the information to adjust your system EQ, whether on the WING’s main outputs or via system DSP.

Room tuning is its own deep subject, but with your signal properly configured, you’re ready to begin analyzing and tuning your room like a pro.

Tools Mentioned:

Behringer WING Digital Mixer
Onboard Oscillators 1 or 2
Measurement Microphone (like Behringer ECM8000)
Room Analysis Software (e.g., Smaart, Room EQ Wizard)

Final Tip: Keep your pink noise channel muted when not in use. Accidental loud pink noise bursts during a service can be distracting and potentially harmful to speakers.
