Product Overview
SYNCO G2 Digital Wireless Microphone is a dual-transmitter, one-receiver 2.4GHz wireless mic system built for capturing voice while keeping your camera or phone connection simple. This guide is based strictly on the official SYNCO documentation for the SYNCO G2 Digital Wireless Microphone.
The kit pairs two TX transmitters to one RX receiver, so you can record two people into a single recording device. It also includes gain controls per channel on the receiver and a switchable low-cut filter, which helps manage levels and reduce unwanted low-frequency rumble when needed.
If you are moving from a wired lavalier to a wireless setup, the SYNCO G2 Digital Wireless Microphone focuses on fast power-on pairing and direct 3.5mm output to common devices like cameras and phones (with the correct cable or adapter).
Best suited for:
- Two-person recordings where you want separate transmitter channels feeding one receiver.
- Creators who need on-device level control using the receiver gain buttons instead of relying only on the camera preamp.
- Shoots that benefit from a low-cut option to reduce bass-heavy noise sources.
Consider alternatives if:
- You require stereo recording into a phone, since stereo mode is not available on phone devices.
- You need a system designed for headphone loads over 100 ohms, because the monitoring jack is specified for headphone impedance under 100 ohms.
Knowledge value: the manual recommends keeping your camera recording level low (about 1/2 to 1/3) because many cameras have noisy preamps, then using the G2 gain control to set a cleaner overall level. This approach often reduces hiss compared to pushing camera gain higher.
How to Use SYNCO G2 Digital Wireless Microphone
To use the SYNCO G2 Digital Wireless Microphone, charge the TX and RX, power them on, let them connect automatically, then route the receiver audio output to your camera or phone with the correct 3.5mm cable. Use the receiver gain controls to set a clean signal and enable low cut only when low-frequency noise is a problem.
SYNCO G2 wireless microphone setup for camera or phone
Connect the RX receiver to your recording device using the included 3.5mm cable type that matches your input. For phones, use the 3.5mm TRRS phone cable, and for cameras, use the 3.5mm TRS camera cable. If your device requires an adapter (such as certain Apple devices), use an MFi-certified adapter as shown in the official documentation.
Power, mute, and basic recording
On the TX transmitter, long-press Power (MUTE) for 2 seconds to turn the system on or off. Short-press the same control to mute or unmute the microphone so you can silence the channel without stopping the recording.
Using an external mic input
The TX supports an external mic connection through its 3.5mm input. The documentation specifies TRS Mic Only, so use a compatible TRS lavalier and insert it fully to avoid intermittent audio.
Monitoring audio while recording
The RX includes a 3.5mm monitoring jack for headphones. For reliable monitoring volume and performance, use headphones with impedance under 100 ohms as specified.
Receiver gain control and mono or stereo mode
Use the RX controls to manage levels at the source, which helps when your camera preamp is noisy. On the RX, short-press Power(Mono/Stereo) to switch between mono and stereo recording modes, and use the per-channel gain buttons to adjust Channel A and Channel B levels in steps from 0 to 15.
Note: Stereo mode is unavailable in phone devices, so phone recording will not output stereo even if you select it on the receiver.
Low cut filter
Short-press Low Cut on the TX to toggle a 150Hz low-cut filter on or off. Turn it on when handling noise, wind rumble, or other low-frequency interference is affecting speech clarity.
Setting cleaner camera levels
Many cameras add audible noise when their recording level is set too high. The documentation recommends setting the camera recording level low (about 1/2 or 1/3) and then using the G2 gain controls to reach the final level, which can produce a cleaner signal.
