A wireless microphone system provides great advantages for content creators. It enables you to make use of simple setup and eliminates the need of cables to reduce the risks of tripping. There are various types of wireless system on the market. And the dual channel wireless microphone system gains much popularity. If you are new to it, read on and get information including:
- What does it consist of?
- When to use it?
- What benefits can you get?
- Which wireless frequency is better?
What is dual wireless microphone system?
Dual wireless microphone systems are made up of three basic parts: the microphone, two transmitters, and a dual-channel receiver.
A wireless system will typically include one of three mic types: headset, handheld, or lavalier.
As for transmitter, its role is to transform the audio signal it gets from the microphone into a signal that can be picked up by the receiver and wirelessly sent. In digital wireless systems, this procedure entails transforming the analog mic signal into a digital signal, which is then transmitted to the receiver as a series of 1s and 0s through a radio connection.
The receiver is located at the opposite end of the radio connection. It extracts the digital signal's 1s and 0s and transforms them back to the audio stream. It comes in types of bigger desktop machines or smaller camera-mounted units or beltpacks.

When to use it?
Have you ever encountered a circumstance where you needed to covertly and clearly record audio from two distinct sources while filming in the field? Perhaps you were shooting a two-person interview, or perhaps you were speaking with someone for a documentary and wanted to capture both your questions and their responses.
In this case, if you record your audio straight into a camera, you've probably run into a problem because most DSLRs only have one microphone input. However, there is a fairly straightforward solution that is really inexpensive and quite quick to set up for recording two mics into a single camera.
You can use dual channel wireless microphone system for recording two-person interviews or presentations. When filming, be sure that both subjects are speaking clearly and understandably. The ideal option in this situation is a wireless microphone since you can record near to the sound sources while standing farther away to get both subjects in the shot.
What benefits does 2 channel wireless microphone system bring to recording?
As aforementioned, your two audio signals will be merged into a single input while remaining independent while recording to the left and right channels of your camera's stereo microphone input when using two microphones. And this helps you to monitor separate audio channels and make adjustments independently.
For example, when you record with the SYNCO G2(A2), a dual wireless microphone with TFT display to record a two-person interview, and find one channel is louder and near to peaking, you'll be able to readily identify which mic this is and tell the speaker to lower their voice or bring the gain down on their receiver.
Keeping the two signals on distinct channels is also important for post-production since it allows you to edit and mix the two sound sources independently.
For instance, you may quickly replace audio that is useless from one microphone with clean audio from the second microphone if you are utilizing a dual-mic setup to guarantee you have a backup of your recording. You may also just enhance one subject's track to balance the audio if you're recording a two-person interview and one subject has a quieter voice than the other.
Which is best dual channel wireless microphone system, digital or analog?
Despite their name, digital wireless systems require analog carrier signals just like analog systems, hence they are not entirely digital. The primary distinction is that digital systems transmit ones and zeros over the signal instead of just pure analog audio.
How come you would want to do this? Simply put, digital technology makes it simpler to remove noise. Professional-grade analog wireless systems effectively reduce background noise. Despite this, signal quality degradation is still a possibility. Contrarily, digital wireless systems encode your audio as digital at the transmitter, transmit it to the receiver, and then decode it as analog at the receiver. Your receiver doesn't even consider analog noise or interference because it solely works with digital data. Anything that isn't a continuous stream of ones and zeroes is simply ignored.
Thus, using digital is recommended, right? No, not always. To achieve greater audio quality, digital units occupy a little bit more of the frequency spectrum, which is already in short supply. Additionally, they may add delay to your system. When picking the finest wireless microphone system for you, keep in mind that high-quality analog wireless systems may compete with digital wireless systems in terms of audio quality and usability.
