As we all know, in addition to the picture quality, the audio is equally important in video creation. No matter how good the picture is, if the radio is not good, no audience will be willing to watch it. In many cases, even if we use a professional external microphones or wireless microphones in the early stage of shooting, it is inevitable that we will encounter popping sounds that cannot be repaired later due to setting errors. Or we were shooting in a venue with many sources of interference, and we didn’t find the signal interruption of the wireless microphone at the scene. When we went back to edit, we saw the video with intermittent sound. Some footage can indeed be retaken, but many great moments only happen once.
In response to the above-mentioned pain points, COMICA launched the BoomX-D PRO wireless microphone set. The biggest highlight of this microphone is its built-in 8GB storage space, which supports real-time recording and safe track backup. In addition to effectively preventing popping noises, it can also be used alone as a recorder, making shooting more secure and material safer.
Packaging & Accessories
In terms of packaging, a white-backed carton is used, with a picture of the appearance of the microphone printed on the front, and a label of the corresponding color on the upper right corner.
On the back of the box is an overview of the main functions and installation diagrams. It can be seen from the picture that this microphone set is available in black and white colors.
After opening the package, it is a nice storage bag. The central LOGO embodies the main orange color of the COMICA brand.
The complete microphone set is placed in the storage bag. Below is the one for two wireless microphone, and in the top net pocket are all accessories.
The accessories are also very complete, including 3.5mm TRS to TRRS mobile phone audio cable, 3.5mm TRS to TRS camera audio cable, 90° audio cable for Sony cameras, three-interface charging cable, lavalier microphone, windproof hair ball, reset card pin and manual.
The transmitter and receiver (black suit) actually look a darker gray. The brushed craft shell and piano black screen are outstanding in appearance design among many similar products, both of which are equipped with color display.
The size of the transmitter is 39*22*55mm and the weight is 29g. Information such as remaining power, connection status, mute status, real-time volume and recording time can be displayed on the screen.
Backup Recording: The biggest highlight of the transmitter is the built-in 8GB storage space for audio backup, so even if the wireless signal is interrupted, the audio material will not be lost. We can also get rid of the shooting equipment and use it as a standalone recorder.
There is a Type-C charging interface on the side, a built-in 330mAh battery, and a battery life of 4.5 hours. Below is the orange record button.
The other side is the power and mute buttons, and the bottom is the PAIR pairing button.
The top is the microphone head and 3.5mm audio input interface. At the same time, you can see that there is a small rectangular hole on the right side of the interface, which is a custom bayonet for fixing the lavalier microphone audio cable. With COMICA’s lavalier microphone, it can effectively prevent the audio cable from accidentally falling off due to pulling.
When you do not want the microphone to appear in some shootings, you can connect the lavalier microphone to the 3.5mm audio input interface mentioned above.
Inside the metal mesh is an omnidirectional microphone with a frequency response of 80Hz-20kHz. The sampling rate is 48kHz and the bit depth is 16bit. According to the official data, this is a microphone that meets the standards of broadcasting and recording.
You can also install a windproof hair ball when shooting in a noisy outdoor environment to reduce the interference of wind noise and radio as much as possible. In addition, COMICA’s windproof hair ball is completely set on the microphone head, which is stronger than most magnetic suction designs on the market.
Next, let’s learn about the receiver. The appearance size is 39*22*55mm, the weight is 29g, and the volume and weight are exactly the same as the transmitter.
Safe Audio Track: The biggest highlight of the receiver is that two different audio tracks are output in safe mode. One of them is normal audio, and the other is a safe track after reducing -6dB. This means that the security of the material is greatly improved to avoid the impact of popping and sound distortion on the material, which is especially important for videos that cannot be re-shot.
It also has a color display that can be used to display the current mode, remaining battery, real-time volume and safety track settings.
The top of the receiver is an audio input interface, which supports an external lavalier microphone. The other is the monitor headset interface, you can wear the monitor headset during rigorous creation to master the more accurate radio state.
There is a Type-C charging interface on the side, a built-in 330mAh battery, and a battery life of 6 hours. In addition to charging, this interface also takes into account the data transmission function, which is used to connect to a computer to export recording files.
On the other side are the on/off and mode switching buttons, as well as the volume setting buttons for two backup safety tracks.
The backs of the transmitter and receiver are all equipped with elastic back clips, which are easy to fix and wear.
When in use, clip the receiver to the camera through the elastic back clip, and then connect the microphone and shooting equipment through the corresponding cable to use. The picture above shows connecting the camera using the Sony-specific audio cable included in the kit.
Also use the elastic back clip to clip the transmitter to a collar or strap etc. This is the mainstream installation method for most wireless microphones at present, and it is very convenient to disassemble and assemble the transmitter and receiver.
