Function Description
The Godox WEC-S systems are wireless lavalier microphone systems that transmit audio signals over the 2.4GHz frequency band. They are designed to capture clear and stable sound, offering features like noise reduction and flexible audio output options. The system includes a transmitter, a receiver, and a charging case.
The transmitter is a compact unit that clips onto clothing, typically near the collar, to capture audio. It features a power switch button, a pairing/denoise button, a built-in microphone, a back clip, an indicator light, a USB-C charging port, and charging points.
The receiver connects to a Sony camera via a hot shoe or to a smartphone via a 3.5mm audio cable. It can also function as an individual microphone. The receiver includes a digital/analog audio mode switch button, a receiver's mic switch button, a USB-C port, a 3.5mm audio output port, a power switch button, a pairing/volume+ button, a model/volume- button, a hot shoe, charging points, a hot shoe detaching button, a built-in microphone, a hot shoe connecting indicator, and a pairing indicator.
The charging case is used to charge and store both the transmitter and receiver. It has slots for the transmitter and receiver, an internal status indicator, external charging indicators, a USB-C charging port, and a reset hole.

When put into the charging case, they will turn off. If unpaired, the transmitter and receiver will turn off after 5 minutes.
- Pairing: Press and hold the pairing/denoise button on the transmitter and the pairing/volume+ button on the receiver for 2 seconds to pair them. They will exit pairing status once paired, or after 10 seconds if unpaired.
- Indicator of transmitter flashes green rapidly (0.25s): Pairing status.
- Both indicators of receiver flash green rapidly (0.25s): Pairing status.
- Indicator of transmitter is constant on green: Paired.
- TX1 indicator of receiver is constant on green, TX2 indicator of receiver is off: One transmitter and one receiver are paired.
- Both indicators of receiver are constant on green: Two transmitters and one receiver are paired.
- Denoise Function: Press the pairing/denoise button on the transmitter to turn on or off the denoise function. When the denoise function of one transmitter in WEC-S Kit2 is turned on, the other transmitter will be turned on simultaneously, and the same applies when the denoise function is turned off.
