DJI Mic 2 noise cancelling, gain and receiver settings

To turn on noise cancelling on the DJI Mic 2, press the transmitter's power button once; its LED turns yellow. You can also swipe up on the receiver and tap the noise reduction icon for each transmitter. For gain, press the receiver dial and turn it, or set transmitter and receiver gain in the swipe-down menu. A good starting point is to pick your camera under Recommended Camera Settings, turn camera gain down, and keep the receiver's level bars out of the red.

Noise cancelling

On the transmitter: press the power button once to toggle. This works when Noise Reduction via Button is on, which is the default since January 2024 firmware.
On the receiver: swipe up on the left (TX1) or right (TX2) side of the home screen and tap the noise reduction icon.
LED: solid yellow when it's on and linked. Blinking yellow means it's on but the transmitter isn't linked.
Not available over Bluetooth to a phone.

Mic 2 noise cancelling is on or off; there are no levels. It's good for steady background noise like air conditioning, traffic or crowd hum. It can make voices sound processed, so leave it off in quiet rooms. If you're recording a backup internally in 32-bit float, you can also clean noise later in software.

Gain

There are two gain stages:

Transmitter gain (Transmitter Settings): the input level at the mic. Lower it if the transmitter's volume bar turns red. It also changes the internal recording level.
Receiver gain (press the dial and turn, or Receiver Settings): the output level sent to the camera or phone.

With a camera, DJI recommends raising receiver gain and lowering camera gain. Choose your camera brand and model in Recommended Camera Settings and the receiver sets a matching gain. If your camera isn't listed, choose None and adjust while monitoring with headphones in the receiver's monitor port. DJI publishes recommended camera settings on the Mic 2 downloads page.

With a phone, the phone's own gain is usually automatic, so set the receiver to a moderate level and test.

Low cut

Low Cut in Transmitter Settings filters sounds at 100 Hz and below: rumble from traffic, wind, handling and HVAC. Turn it on for most voice recording. With low cut on, the frequency response is 100 Hz to 20 kHz; off, it's 50 Hz to 20 kHz.

EQ

The Mic 2 has no user EQ on the receiver. DJI tuned the built-in EQ in August 2024 firmware for a fuller, brighter sound, so update if you haven't. See Mic 2 firmware update.

Settings that help in noisy places

Situation	Settings
Quiet room	NC off, low cut on, Mono or Stereo
Street or café	NC on, low cut on, windscreen if outdoors
Loud event	NC on, lower TX gain, Safety Track
Wind	Windscreen, low cut on
Two speakers	Stereo, so each voice is on its own channel

Safety Track outputs a second copy 6 dB lower on the right channel, so a sudden shout is less likely to clip. See recording modes.

Other useful receiver settings

Power On/Off Camera Simultaneously: the receiver follows the camera's power over the 3.5 mm cable.
Receiver Auto Off and Transmitter Auto Off save battery.
LED Indicator off hides the transmitter lights on camera.
