5. Setup
5.1. Charging the Devices
Before first use, fully charge both the transmitter and receiver using the provided USB charging cable. The charging cable features a USB-A connector on one end and two USB-C connectors on the other, allowing simultaneous charging of both units.
- Connect the USB-A end of the charging cable to a USB power adapter (not included).
- Connect the two USB-C ends to the charging ports on the transmitter and receiver.
- The charging indicator will illuminate during charging and turn off when fully charged.
5.2. Connecting to a Microphone (XLR)
- Plug the transmitter directly into the XLR output of your dynamic microphone.
- Plug the receiver into an available XLR input on your audio mixer or PA system.
- Ensure both devices are powered on. They will automatically pair.
5.3. Connecting to an Instrument (Guitar/Bass)
- Attach the 6.35mm to XLR plug adapter to the transmitter.
- Plug the adapter-equipped transmitter into the 6.35mm output jack of your instrument (e.g., guitar, bass). The 180-degree rotatable design allows for flexible positioning.
- Attach the XLR to 6.35mm plug adapter to the receiver.
- Plug the adapter-equipped receiver into the 6.35mm input of your amplifier or audio interface.
- Ensure both devices are powered on. They will automatically pair.
