When you open the DJI Mic 2 charging case, the receiver will automatically start up and link with the two transmitters. The touch panel on the top of the receiver displays the remaining battery power and the transmitter's internal recording capacity in hours.
When you first start the receiver, the first thing you do is set the language. This time I chose Japanese.
Next, set the year, month, and date.
Set the time.
This is OK. When connected to a transmitter, the input level of the connected transmitter will be displayed on the touch panel of the receiver.
This time, I tried recording by connecting a DJI Mic 2 receiver to the Panasonic
The DJI Mic 2 receiver is intended to be connected to a variety of cameras, and is equipped with a 'preset function' that allows you to recall gain settings prepared in advance for each camera model. Therefore, swipe up on the touch panel to call up the settings screen, select and tap 'Receiver settings'.
Select and tap Recommended camera settings.
Select your camera brand and model and recall your presets.
Select 'Panasonic' as the brand.
Select 'GH6' as the model.
The brands and models for which preset settings are registered with DJI Mic 2 firmware version 04.02.01.13 are as follows.
·Sony

・Fuji Film

Once the settings are complete, attach the receiver to the camera's mount shoe.
This is what it looks like when you attach the receiver to the mount shoe.
Insert the included 3.5mm TRS camera audio cable into 'OUT' on the left side of the receiver, and insert the other end into the camera's microphone input terminal.
Installation is now complete.
The transmitter will automatically link to the receiver when you take it out of the charging case. You can use the clip or magnet on the back to attach it to your clothes.
Below is a movie comparing recording with GH6's built-in camera and recording with DJI Mic 2. With the built-in camera, the sounds of the circulator and air conditioner spinning at the editorial staff's feet can be heard, and the voices of the editorial staff who are standing about 1.5 meters away from the camera echo inside the room, making it difficult to hear them. . On the other hand, in the latter half of the recording using DJI Mic 2, you can see that the voices of the editorial staff wearing the transmitter are clearly being picked up.
One of the improvements that DJI Mic 2 has made over the previous generation model, DJI Mic , is support for 32-bit float recording. DJI Mic 2's transmitter can normally record at 48kHz 24bit, but by turning on 32-bit float recording, you can record with low noise without having to adjust the microphone input level.
To turn on 32-bit float recording, you need to configure settings from the receiver. Call the settings screen on the touch panel and select 'Transmitter settings'.
Select '32-bit float recording'.
It is OK if you switch it to 'ON'.
The following movie shows the actual reading while changing the volume of the voice, recorded with normal recording and 32-bit float recording. Both have some pop noise from the breath, but while with normal recording the sound cracks up a bit when you speak out loud, with 32-bit float recording I get the impression that there is no sound cracking even when you speak loudly. Even in loud performances or noisy environments where normal recording would result in crackling, 32-bit float recording allows clear recording without the need to set the input level.
DJI Mic 2 also supports smart noise canceling. Smart noise canceling can be turned on by tapping the icon displayed on the far right of the receiver's touch panel.
In the movie below, we compare recordings with noise canceling turned off and with noise canceling turned on. When noise canceling is turned off, the sound of the circulator and air conditioner placed at your feet is heard in the background of the editorial staff's voice. However, when you turn on noise canceling, you can clearly see that the noise in the background is removed and only the voice is clearly recorded when you watch the movie.

If you use a microphone to record a video, you must first set the input level and gain, otherwise the sound may crack and you will not be able to record clearly. However, by using the preset function and 32-bit float recording, DJI Mic 2 can make high-quality recordings without any settings. The receiver and transmitter are connected just by taking it out of the charging case, so there is no need to set up the receiver link each time, and the big point is that even people who are not familiar with recording equipment can use it easily. Furthermore, since it's a wireless microphone, I thought it was a nice feature to be able to check the remaining battery power every time I opened the case.
