Achieving high-quality, distortion-free sound in a live event environment is not just about having expensive equipment—it’s about using it correctly. One of the most critical techniques for achieving clear, professional sound is gain staging. Yet, many DJs, sound engineers, and event technicians overlook this foundational concept, leading to feedback, clipping, or a weak signal.
Whether you’re mixing a concert, hosting a conference, or managing a church service, knowing how to set proper gain staging will elevate your audio quality.
What Is Gain Staging?
Gain staging is the process of managing audio signal levels at each point in your signal chain—from microphones and instruments to the final output. The goal is to keep the signal strong enough to avoid noise but not so strong that it distorts or clips.
This becomes especially important in live environments where audio conditions are unpredictable. Proper gain staging ensures clean, powerful sound whether you’re on a small stage or managing an arena setup.
Why Gain Staging Matters in Live Events
Live sound systems are complex, often involving multiple input sources, outputs, monitors, and effects. Without gain staging:
- Microphones might sound too quiet or distorted.
- Audio signals can clip, causing harsh feedback or damage to speakers.
- The mix lacks clarity and dynamic range.
- You lose control over volume during performance peaks.
Correct gain staging prevents these issues, offering more headroom, clarity, and consistency.
Guide to Setting Proper Gain Staging
1. Start with the Trim (Gain) Knob
Every channel on a professional mixer, like the durable audio mixer from 5 Core Business, has a gain or trim knob. This controls the amount of input signal being sent into the channel.
- Turn down the fader.
- Set gain to the lowest level.
- Speak or play the source (e.g., microphone or instrument).
- Slowly raise the gain until the signal hits around -6 dB on the channel meter—this gives you headroom while avoiding clipping.
2. Use the PFL (Pre-Fader Listen) Button
Many mixers, including the best audio mixer from PLS, have a PFL (Pre-Fader Listen) feature. This lets you monitor the input level before the fader affects it.
This is essential for gain staging because it lets you check the raw signal strength without EQ or effects. Use your headphones to listen and adjust gain appropriately.
3. Set Your Channel Faders
After adjusting gain, set your channel faders to unity gain (marked “0” on most mixers). This ensures you’re neither boosting nor cutting the signal post-preamp, maintaining a clean signal flow.
4. Balance with the Master Fader
Once each channel is properly staged, control the overall volume with the master fader. This helps avoid cumulative distortion that can occur when multiple channels are too “hot” (overly amplified).
5. Monitor the Signal Chain
Good-quality audio mixers like those from 5 Core provide clear level indicators, EQ options, and PFL/AFL buttons that help you monitor each stage in the signal chain. Always keep an eye on the LED meters to make sure you stay out of the red zone.

Common Gain Staging Mistakes to Avoid
- Setting gain while faders are up – Always mute or drop faders before adjusting gain.
- Ignoring PFL meters – They give the most accurate input signal readout.
- Over-relying on EQ for volume – EQ shapes tone, not gain.
- Pushing master output to compensate for low channel gain – This introduces noise and distorts the signal chain.
