SYNCO G2A2: The New Standard In The Lavalier Microphone System

The lavalier microphone systems have been in use for years now. They provide unparalleled wireless audio connectivity and capturing abilities making them absolute necessities for interviews, podcasts, filmmaking and broadcasting. The main benefit of lavalier microphones is their discretion. They can be positioned close to the mouth while remaining out of sight. However, the lavalier mics from the past had their fair share of limitations. From taking too much time to set up, to weak wireless connectivity and non-availability of multi-channel recording and broadcast, they can be difficult to work with sometimes. 

The SYNCO G2A2 has tried to address these problems with the latest advancement and patented technology. 

The Synco G2A2 is a wireless microphone system that works over 2.4 GHz digital transmission technology. It processes and sends clean and clear audio wirelessly and helps you record crisp, high-quality sound without any expensive system. The microphone system consists of two compact transmitters and one receiver. The transmitters have built-in microphones to record clean audio without any hassle. However, they also have separately included lavaliers that can be attached to the transmitters for better quality sound and ease of use. 

Working Principle

Synco G2A2

The total microphone system has one receiver for both transmitters. The receiver can be connected to any DSLR, camcorder and even a mobile phone. Connection is done via a 3.5 mm jack, which is fairly easy and straightforward. Now when the whole system is up and running, two microphones start sending audio signals to the receiver and audio is recorded on the device, with which the receiver is connected.

The main distinction of Synco G2A2 is the presence of screens on the receiver and the transmitters. It is mostly similar to the erstwhile model G1 in many other senses but the display sets them apart in their exterior look.  The TFT screen shows battery and audio levels, selection of channels and which microphone is in use. 

Switching On

Synco G2A2

While powering it on, the Synco G2A2 takes only 6-7 seconds to start. Although the previous model G1 takes less time to start which is almost 2-3 seconds, a six seconds start time is quite reasonable as well. It is one of the advantages of Synco G2A2 that it takes so little time to get started. 

The screen shows clearly which microphone is active and transmitting. If the display shows “A+15”, it means the A microphone is active and the audio level is at +15 dB. Turning the B microphone on will also show the audio level of the B microphone. The audio gain can be changed by pressing the side button several times. The audio levels go from 0,3,6,9,12 and up to 15 dB To customize the audio level more, you can change the audio setting of the device with which the receiver is connected. 

When the transmitter and the receiver both are working properly, the audio levels are highlighted in green. 

General Features

Power Saving

After 2 minutes of inactivity, the screen of the transmitter turns off to save power. However, it can be turned back on just by pressing the power button. The power button also doubles up as the mute button.

On the other hand, the receiver’s screen is always turned on due to the requirement of constant monitoring and settings. 

Lightweight and compact

The whole system is substantially light and each device only weighs 34 grams. This has been a major advantage because it is meant to do even outdoor shoots and you need to pack as light as possible. The buttons are quite sturdy and hold well to pressure. Overall the build quality is reasonably good and an actual step up from the G1. 

A useful update is the included USB-C cable that has three connections to charge all devices at once.

Battery Life

The battery life depends on a lot of factors like screen time, change of settings among others. However, on average, you can use all the devices for almost 6 to 7 hours. For a device of such lightweight, it will be more than enough battery backup.  

They also have upgraded the charging process from the G1. The system now comes with a USB-C cable, with which all the 3 devices can be charged together. You can charge the devices up to 50% in only 40 minutes and 80% in only 1 hour.

Tracks and channels

Two separate transmitters can be connected to one camera with the help of the receiver. You can then separate the two channels and keep them as right and left in case of stereo. During post-production, you can separate the audio tracks and work on them separately. 

Most of professional cameras have two different audio channels, left and right, but only a single microphone input. With any other mic, it is not possible to plug in two of them in a single input. Evidently, this type of system can solve that problem with the help of a 2-in-1 channel.

Clipping the transmitters

The transmitter’s internal mic delivers good quality audio with or without a dead cat on. So, if you don’t want to use a lapel, you may leave those wires altogether. Just clip the transmitter on the artist’s shirt and start recording. 

On the other hand, if you want to hide the transmitter, you can always plug in the lavalier from the package. Then you can keep the transmitter in the artist’s pocket or clipped on his belt. 


The exact range is difficult to measure because a lot of things can affect the range. While it has been proven that the range is greatly increased from the previous model G1 it is actually hard to quantify that. According to the manufacturer, with a clear line of sight, the 2.4 GHz frequency of the G2 (A2) can reach 70 m unhindered up from the G1’s 50m. However, this can change a lot depending on what kind of interference is present and where the mics are placed. 

For example, the range will always be higher outdoors than indoors with a lot of equipment. However, for short-range requirements, this should not be a problem.

Screen Information

The screen contains battery capacity information in the form of a bar. While it has been the norm for quite some time in the world of electronics, being able to see the remaining battery in percentage would have been better. 

The screen of the transmitter shows the low cut filter and mute status, but the receiver’s screen does not show any of these. So, if any artist accidentally clicks the mute option, the cameraman won’t have any idea about it. While it may not be a deal-breaker, having these options would have helped. 


The connectivity across devices is what makes it truly versatile. It doesn’t matter whether you are a beginner or a professional, you can connect it to any phone or professional-grade mirrorless camera and record great audio. Making the connections are also quite easy and hence you can set it up and start working with it in a moment. 

Moreover, the integrated signal processing lessens the latency and makes the quality of sound live broadcasting worthy.


This whole Synco G2(A2) system is super affordable. The system provides unparalleled sound quality and monitoring in its price segment. 

Pros of Synco G2A2

The Synco G2(A2) is one of the most affordable yet powerful lavalier microphones. The upgrade from the G1 model has improved usability greatly. Overall the microphone has multiple positive features that make it one of the most useful purchases.

Two Microphones in one receiver

  • The dual channel receiver saves critical space in your equipment bag when you are going for outdoor shoot by needing a single receiver for two separate microphones. Other lavalier mics need separate bulky receivers for each microphones. The single receiver of Synco G2(A2) is compact and lightweight making this an appropriate portable microphone system. 

  • The receiver has an attached belt clip, which can double as a shoe mount adapter, necessary for your DSLR. 

Clip On Transmitters with Built In Mic

  • Every transmitter has its own built-in microphone and also a 3.5mm jack input where you can attach its individual lavalier microphone, included with this system.
  • You can clip the mic on your clothing without requiring any wired system and have the best possible wireless system in a minute. The transmitter can also be used as a handheld microphone if you don’t want to clip it onto your clothing. 

  • You can use a low cut filter on the built in microphone to remove any unwanted noise and pop. 

Easy to operate system

Just pressing the pairing button can pair the systems automatically, so no complicated tinkering with settings.

You can set the gain of each microphone individually by clicking the side button multiple times. 

The TFT display on each of the transmitters and receiver shows battery life, power, audio levels and mute.

You can record both mono and stereo audio with this. While recording mono, the individual microphones work for a single audio source, working as left and right of the sound source. And during stereo recording, you can use the transmitters for different persons with individual recorded tracks, which you can edit and adjust separately later. 

The inbuilt battery powers the devices for up to 8 hours. And charging the batteries takes only 1.5 hours with the 3-in- 1 charging cable included with this set. 

Real time monitoring

If you have attached this to a camera and your camera doesn’t have a headphone jack, you can connect your headphone to the transmitter’s headphone input to get real-time audio and monitor that for quality. 

2.4 GHz Signal

This wireless microphone system operates in the 2.4 GHz frequency which is not in use by any TV, Radio and UHF microphone. So, there will be zero chance of transmission interference. 

The system can change the transmission frequency, if necessary, to avoid noise, dropouts and any other interference. This works for a line of sight distance of 164 feet (without obstacles) and 98 feet (obstacles). 

To have the best possible sound capture, try an obstacle-free environment with no or minimal 2.4 GHz signal traffic. 

Cons of Synco G2A2

  • The TFT screens attached to the transmitters and the receiver are not very bright. In indoor shoots, that is clearly visible but during outdoor shoots, sun’s glare can greatly diminish the screen’s visibility. In well-lit conditions, even reading the settings can be a problem sometimes. 
  • The receiver’s display hibernates after 2 minutes and 45 seconds, which is not a major problem but can be irritating when you are live monitoring the status.
  • The individual devices are compact and lightweight, but the material does not seem premium and feels plasticy. 

Final Verdict

Synco G2A2

The Synco G2A2 has all the features you may need during a live shoot indoor or outdoor. Starting from dual-channel recording to smart TFT display showing all the necessary information, it has covered a lot of grounds. 

The range, sensitivity and performance are better than the previous model Synco G1 and this upgrade, it doesn’t leave much to be desired.

There are some things which could have been better, as the information on the receiver. It would have been better if the camera person could see the mute or recording status on the receiver. Or they could have made the system with more durable and sophisticated materials. But there are enough positives to ignore those. 

One of the most important things about the Synco G2A2 is its price. It is super affordable and provides professional-grade recording capabilities with the price of a simple lavalier microphone. This affordability makes it the ideal choice for both beginners and professionals. 

It is already making a lot of noise in the wireless microphone segment and rightly so.
