[ Anchor Technology Experience ] With the popularity of smartphones in recent years, short video shooting has become easier and easier. Just raise your phone and press the shooting key to start your own creation. In order to meet users' needs in this regard, mobile phone manufacturers also optimize video shooting needs from both software and hardware, such as the Vlog mode.
I wonder if you have noticed that it is difficult to include sounds from afar when shooting videos with your mobile phone. Generally, the effect is good if it is within 1m. In addition to some wind noise, you can still hear the voices clearly. The radio of a mobile phone that exceeds this range is really not a good idea. This problem does not only appear now. There are many products on the market that can also solve this problem, such as the "little bee" we often use.
I also encountered this problem when I was shooting videos before, and I borrowed my friends' little bees. This time, the Lenovo member trial product has a set of Lenovo wireless lapel microphone MC550, so of course I have to apply for a trial.
The Lenovo wireless lapel microphone MC550 I got is a white model, and you can also choose a black version. I personally think white is more versatile. The packaging of Lenovo wireless lapel microphone MC550 is extremely simple. Inside the box is a portable storage box that is resistant to rain, dust and pressure, and can basically cope with various complex environments in daily use.
portable box is neatly arranged with two transmitters and one receiver. The white front panel is paired with a golden case, and their compact body looks very delicate, like a work of art. This wireless microphone set is also equipped with two custom snow-white windproof velvet, a charging cable, a 3.5mm TRS to TRS audio cable and a 3.5mm TRS to TRRS audio cable.
Back to the product, Lenovo wireless lapel microphone MC550 adopts a one-to-two design, which means that it can collect two audio channels at the same time, and can be used to do one-to-one interviews or two-person chat videos. The front of the
transmitter adopts a two-stage design, and the upper half is four indicator lights, namely charging/low power indicator light, connection indicator light, noise reduction indicator light, and reverb indicator light . It is mainly used to prompt the working status of our machine.
left side of the body are the power button and the volume adjustment button. The volume provides three-speed adjustments, and the default mid-range when powering on is turned on. Press "Volume+" long to turn on and off the noise reduction function, and press "Volume-" long to turn on and off the reverb function. Just above
is the 6027 integrated omnidirectional capacitor microphone head, with a minimum pickup intensity of -75dB and a maximum pickup intensity of 105dB. From small needles to small, as big as the roar of the plane, can be captured perfectly. In addition, it can deeply control the noise floor on the analog signal and filter out various electromagnetic interference . Simply put, it is hardware-level noise reduction. It is recommended to install windproof velvet when using it, which has better noise reduction and audio effects.
reverberation function can enhance the three-dimensional sense of the sound, create an empty space, and let the sound spread and echo inside, which can make the sound levels of live broadcasts and short videos richer.
on the right side is the headphone output interface and the Type-C charging port. The audio effect is debugged in real time through this headphone output port. Compared with the design that monitors on the receiver, this design is more conducive to real-time mastering of the audio status, and can be adjusted as soon as possible when encountering emergencies. The charging interface of
Type-C is more versatile, and the charging cable of the mobile phone can also charge it, but you need to see if the output of the charging head is 5V 1A. The panel design of the
receiver is the same as that of the transmitter, but the types of indicators are somewhat different. From left to right, the charging/low power indicator, connection indicator, and mute indicator are respectively. The volume key on the left side of the body is the volume key, which can adjust the volume output to the audio of the video recording device. The same three-speed adjustment is the default mid-range.
power key is set at the top, and this design allows us to easily distinguish the transmitter and receiver. In addition to controlling the power switch, the power button can be pressed twice in a row to control whether it is silent. During live broadcast, the audio can be quickly cut off, which is convenient for the director to control the live broadcast content.
The same headphone interface and Type-C interface on the right side of the body. The difference is that the 3.5mm headphone interface of the receiver is a TRS, which is used to transmit the received audio signals to recording devices such as cameras, tablets, mobile phones, laptops, etc. In the recording device, you need to open the corresponding software to collect the sound. For example, when pushing streams in OBS, you need to add this audio to be collected normally. Of course, some devices also have audio recording and video shooting software that come with their own devices can directly receive this sound source, such as iPad, and can be tested using an adapter or directly plugged in a 3.5mm headphone jack.
In addition, you should also pay attention to the specifications of the audio interface of the recording device. Fortunately, the official standard is equipped with a 3.5mm TRS (level 3 plug) to TRS audio cable and a 3.5mm TRS to TRRS (level 4 plug) audio cable. If you don't have a headphone jack, you need to have a 3.5mm TRS to Type-C cable for recording.
Lenovo wireless lapel microphone MC550 is very simple to set up. The receiver and transmitters do not need to be paired. They are automatically connected when powered on. After connection, the respective connection indicator lights are always on. Just connect the receiver to the recording device, and the transmitter is clipped to the collar to start video recording or live broadcast. What attracts me the most is its noise reduction function in addition to its simplicity of deployment, the 6027 integrated noise reduction microphone, high-performance DSP noise reduction chip, and the receiving end matching noise reduction parameters. It combines two audio channels, and outputs the low-noise analog signal to the 3.5mm interface to complete the full-link noise reduction. If you use it to record videos, you no longer need to reduce noise from audio in video editing software, which not only improves the efficiency of video editing but also makes the sound more vivid.
The data transmission between the transmitter and receiver of Lenovo wireless lapel microphone MC550 adopts 2.4G private protocol transmission technology, encrypted data transmission, ensures the security of audio data, and can also achieve stable transmission within 80 meters to meet the shooting needs of various scenes.
Lenovo wireless lapel microphone MC550 has strong compatibility and can adapt to 99% of Apple , Android, Windows, Linux software. It can be easily competent for both mobile phone outdoor live broadcasts or short video recordings. There is no need to worry about the battery life of
. The body has a built-in 300mAh battery, which can achieve a maximum battery life of 8 hours (on the noise reduction and reverb, the battery life will be slightly shortened), and there will be no problem even if you record it for a day outside. The very versatile Type-C interface allows us to quickly charge it, and we can easily charge it in surrounding shops and people without cables.
