Maono WM821 듀얼 무선 마이크 시스템 검토

An audio recorder is a core piece of equipment for any video creator. Whether you’re starting a vlog, podcast, or YouTube channel, one of the first things you’ll need is a microphone system that delivers professional sound. If you’re planning on recording outside of a YouTube studio, you’ll need a recording device that’s portable, cable-free, and still delivers great audio quality.

In this review, we’ll be testing out Maono’s WM821 dual wireless microphone system, which is everything it says on paper, to see if it delivers on its promises.

Maono WM821 Dual Wireless Microphone System: First Impressions and Specifications

Wireless microphone systems are a new technology trend. They come with a transmitter that captures audio and then transmits it to a receiver via a specific radio frequency band (2.4 Hz in the case of the Maono WM821) and synchronizes it with a camera that records video. The WM821 allows two people to record simultaneously using one receiver and two transmitters. When

you first get your hands on the Maono WM821, you will notice how stylish all the parts (including the charging case) are. Inside the case, there are two transmitters and one receiver. Each is lightweight and has a clamp on the back that can be used to attach it to clothing.This design is complemented by the WM821, a wireless system that can be used without cables. With this in mind, moving around while recording is not a problem, so the WM821 is perfect for conducting interviews and recording outdoors.

Before we get into the details, let’s take a look at the full technical specifications list of the Maono WM821 dual microphone system.

Out of the box, you’ll be amazed at how Maono has thought of everything when creating the WM821.

It’s a simple audio recording system consisting of two transmitters and one receiver for 1-2 people. Both the transmitter and receiver feature excellent battery life and a charging case to extend battery life. The loudspeaker and windshield protector are nice extras to make recording even more flexible.

Design and Unpacking

The build quality of the Maono wireless microphone system gives a premium feel right from the moment you open the box. The various parts of the kit are packed separately in small boxes with clear labels. The transmitter with receiver is easily portable in the Maono charging case, and all accessories can be stored and carried using the special carrying pouch included in the package.

What's in the box

When you unpack, here are all the items in the box:

• Maono WM821 receiver
• 2x Maono WM821 Transmitters
• Charging Case
• Audio Cable for Camera
• Audio cable for smartphone
• USB-A to USB-C Cable
• 2 x Lavalier Microphones
• 2 fur windshields
• Maono storage bag

Inside the durable charging case are two pocket-sized transmitters and one receiver. All of this is very lightweight, with each wearable weighing just 35 grams and unnoticeable when worn on clothing.

Each transmitter has a built-in microphone (omnidirectional), so you don’t need to connect a loudspeaker microphone for recording. However, if you prefer to use an external microphone, the Maono kit includes two small microphones. The

transmitter has a power button, a mute button, a pairing button, a low-cut button to remove low frequencies and unwanted echo, and an indicator that shows when the transmitter is on or off.The receiver has a power button and a volume control button that also functions to switch from mono to stereo mode. On the side of the receiver are a headphone jack and an output jack for connecting a headset.

There are also two fur windshields that can be attached to the transmitter to diffuse the audio and improve audio quality. However, the twist-to-lock mechanism does not appear to have been developed yet, and the windshields do not always remain attached to the transmitter when moving.

Audio quality and features

Typically, people choose condenser and dynamic microphone models when they first buy an audio recording setup. If you plan on recording static video in one room, this is a fair choice. However, if you need a recorder that can be used on the go to capture dynamic footage, or if you frequently need to move your recording setup to different locations, a wireless microphone system like the WM821 is a better choice.

Of course, you don’t want to sacrifice sound quality when switching from a standard condenser to a wireless microphone. With the WM821, you don’t have to. Audio recorded with the built-in microphone sounds natural and clear.

When shooting indoors, there’s not much you need to do in terms of setup. First, power up the transmitter and receiver. Then, place the transmitter close to you or use the clip to attach it to your clothing. Then, connect the receiver to your shooting camera using a TRS or TRRS audio cable. When the LED indicators on both devices stop flashing and start glowing steadily, the devices are paired and ready to start recording.

Thanks to the built-in omni microphone, it’s best to add a windshield protector when the shooting location is windy. It reduces background noise without affecting the clarity of your recording.If you don't like how the transmitter looks on camera (especially with the padded shield on), you can use an external lapel mic (or lavalier mic) when recording. The Lav mic included in the kit is very basic, but gets the job done. It's shorter, but long enough to attach to the transmitter and fit in your pocket.

The WM821 model is packed with features that can help improve audio quality when shooting outdoors or when you need to move while recording. One of these features is the low cut filter. It acts as a digital windshield to remove unwanted background noise from your recording.

The dual transmitters are great for a variety of situations. For example, if you need to record two people at the same time. One person is speaking softly and the other is speaking louder, you can set up the transmitters for two separate channels with different gains. Or, if you only have one opportunity to record, you can record a backup copy of the same audio using another transmitter.

Range

The most impressive feature of the Maono WM821 microphone system is its range. Maono promises an extended transmission range of up to 100 meters (328 feet) in normal conditions and up to 400 feet (400 feet) in an open environment when there are no obstacles blocking the transmission signal.

During our testing, we were impressed with the 100-meter range. The recording quality did not deteriorate no matter how far away you were from the receiver. The only requirement is that you have line of sight, meaning there should be no walls or anything between you and the receiver.

Compatibility

The Maono WM821 is compatible with any device that has a 3.5mm port. The microphone kit comes with two connector cables, labeled Phone and Camera, so you can’t get them mixed up.This cable allows you to connect the WM821 to a video camera, DSLR camera, or smartphone. The only exception to this is the iPhone. You will need a Lightning adapter cable to connect the Maono WM821, which is not included in the box.

Battery Life

We’ve already mentioned the WM821’s excellent battery life, which is rated for up to 10 hours of operation. According to Maono, the transmitter can last even longer, up to 12 hours on a single charge. Thanks to the charging case, you can double that number before needing a real charger.

Battery-related life hack: If you’re only using one transmitter, you can swap the transmitter in the charging case for the other transmitter and continue recording.
