# How to Eliminate LED Panel Hum & Mic Interference: Aputure Amaran vs Neewer vs Godox

## Introduction

Content creators frequently encounter two related audio‑visual problems: a low‑frequency hum emanating from LED panels and unwanted electromagnetic interference that contaminates microphone recordings. Both issues degrade production quality and increase post‑production workload. This guide explains how to diagnose the sources of hum, apply practical mitigation techniques, and choose the most appropriate lighting tool for a quiet shooting environment. By following the procedures, one can achieve clean audio while preserving the flexibility of RGB and bi‑color LED panels.

## Step‑by‑Step Instructions

### Step 1: Identify the Hum Source

Begin by powering each LED panel individually while monitoring the audio track with a calibrated field recorder. A consistent 50‑60 Hz thrum indicates mains‑related vibration, whereas a higher‑frequency buzz often stems from switching regulators inside the panel. The [Neewer Magnetic RGB Camera Light](https://amazon.com/dp/B09RB4NVWK?tag=wpem020126-20) uses a 6W LED driver that is praised for minimal flicker, yet its compact design can transmit mechanical vibration through its metal housing. Record the baseline noise level for each unit; this data will guide later mitigation steps.

### Step 2: Isolate Power Supply Noise

Most hum originates from the power conversion stage. Connect the panel to a clean, isolated power source such as a high‑quality battery pack rather than a wall outlet. The [SmallRig RM120 RGB Video Light](https://amazon.com/dp/B0B63CRMKC?tag=wpem020126-20) includes a 5000 mAh battery that provides up to 180 minutes of operation at full brightness, eliminating the need for AC mains during critical recordings. When battery power is not feasible, employ a power conditioner with built‑in noise filtering. Ensure that the USB‑C charging cable is routed away from microphone cables to avoid electromagnetic coupling.

### Step 3: Apply Ferrite Chokes to Audio Cables

Attach ferrite cores to any audio cable that runs near the LED panel’s power cord. The ferrite acts as a high‑frequency filter, suppressing radiated noise that can infiltrate the microphone preamp. This simple component is inexpensive and dramatically reduces the hiss that reviewers of the [Neewer NL-116AI LED Video Light](https://amazon.com/dp/B0D9W57M4Y?tag=wpem020126-20) have noted when using its built‑in USB‑C charging port alongside a microphone.

### Step 4: Use Shielded Audio Connections

Replace unshielded 3.5 mm cables with shielded XLR cables wherever possible. A shielded connection prevents the LED panel’s high‑frequency switching noise from being induced into the microphone line. If the microphone only supports a 3.5 mm jack, place a short segment of shielded cable between the mic and the recorder, and secure the cable so that it does not touch the light’s mounting hardware.

### Step 5: Ground‑Loop Isolation

When both the camera and the LED panel share a common ground, a ground loop can form, producing a low‑frequency hum audible in the audio track. Insert a ground‑loop isolator between the microphone output and the recording device. This device breaks the loop while preserving signal integrity. The isolator is especially useful when using the [Aputure Amaran 150c RGBWW Light](https://amazon.com/dp/B0C38PPFD1?tag=wpem020126-20), which often operates on AC power through a 48 V DC adapter.

### Step 6: Physical Damping of Vibration

Mechanical vibration from the LED driver can travel through the light stand to the microphone stand. Mount the LED panel on a rubber‑filled gimbal or a silicone pad to decouple vibrations. The magnetic rear of the [Neewer Magnetic RGB Camera Light](https://amazon.com/dp/B09RB4NVWK?tag=wpem020126-20) allows it to be attached directly to metal surfaces; placing a thin neoprene sheet between the light and the surface reduces the transmission of hum without compromising the magnetic hold.

### Step 7: Optimize Light Settings for Low Noise

LED panels generate less electrical noise at lower brightness levels because the driver operates below its peak switching frequency. When possible, dim the panel to the minimum level that still provides adequate exposure. The [SmallRig RM120 RGB Video Light](https://amazon.com/dp/B0B63CRMKC?tag=wpem020126-20) offers 100‑level saturation adjustment and 12 lighting effects; selecting a softer effect such as “Paparazzi” or “Fireworks” at 30‑40% brightness often yields a clean audio environment.

### Step 8: Leverage Built‑In Diffusers

Soft diffusers not only smooth lighting but also reduce the intensity of the driver’s magnetic field by adding a small physical barrier. The detachable diffuser supplied with the [Neewer Magnetic RGB Camera Light](https://amazon.com/dp/B09RB4NVWK?tag=wpem020126-20) and the included diffuser for the [Neewer NL-116AI LED Video Light](https://amazon.com/dp/B0D9W57M4Y?tag=wpem020126-20) serve this purpose well. Position the diffuser a few centimeters away from the LED surface to maximize acoustic damping.

### Step 9: Verify with Real‑World Test

After implementing the above measures, record a short test clip with the microphone positioned as it will be in the final shoot. Play back the audio on a high‑fidelity monitor and listen for residual hum. If any noise persists, repeat steps 2‑6, focusing on the cable layout and grounding configuration. The iterative approach ensures that the final setup is both visually and sonically optimal.

## Tips & Pro Tips

- Keep power and audio cables perpendicular to each other; parallel routing amplifies inductive coupling.
- When using multiple LED panels, synchronize their power on/off cycles to avoid cumulative hum spikes.
- For studio environments, consider a dedicated power distribution unit (PDU) with isolated circuits for lighting.
- Utilize the Sidus Link app for the [Aputure Amaran 150c](https://amazon.com/dp/B0C38PPFD1?tag=wpem020126-20) and [Aputure Amaran 200x‑S](https://amazon.com/dp/B08RMS1GZV?tag=wpem020126-20) to adjust color temperature without physically touching the fixture, thereby reducing handling noise.
- When shooting in a confined space, place the LED panel on a small sandbag to add mass and further dampen vibration.

## Frequently Asked Questions

### What causes the low‑frequency hum in LED panels?

The hum is usually generated by the panel's internal driver circuitry or a poorly filtered power supply that produces electromagnetic noise.

### How can I reduce LED panel hum without sacrificing lighting quality?

Use a high‑quality, filtered power adapter, add ferrite beads to cables, and keep the panel away from the microphone and audio gear.

### What simple steps can prevent mic interference from LED lights?

Place the microphone on a boom arm with a shielded cable, use a ground‑loop isolator, and avoid running audio cables parallel to the panel’s power cord.

### Which LED panel is the quietest for [video](#) production: Aputure Amaran, Neewer, or Godox?

Aputure Amaran panels are generally rated the quietest due to better driver design, though high‑end Neewer and Godox models can be equally silent with proper power filtering.

### Can I use a battery pack to eliminate hum from LED panels?

Yes, powering the panel with a clean, isolated battery pack removes AC line noise and often eliminates hum completely.
