2. Setup Guide
2.1 Charging the System
Before initial use, fully charge both the transmitter and receiver using the provided Type-C charging cable. Connect the cable to a standard USB power adapter (not included). The charging indicator lights will show the charging status and turn off when fully charged. A full charge provides up to 5 hours of battery life.
2.2 Attaching the Microphone
Attach the microphone unit to your instrument using the saxophone/trumpet clip. The clip features a rubberized design to protect your instrument's finish. Position the gooseneck microphone to capture the desired sound from the instrument's bell. The gooseneck design helps reduce resonance and minimize key click sounds.

2.3 Connecting the Receiver
Plug the U7 receiver directly into the XLR input of your amplifier, audio interface, or mixer. Ensure the connection is secure. The receiver is designed for direct integration into standard audio equipment.
3. Operating Instructions
3.1 Power On/Off
To power on the transmitter and receiver, press and hold the power button on each unit until the indicator lights illuminate. To power off, press and hold the power button again until the lights turn off.
3.2 Channel Selection
The U7 system offers up to 6 channel options. To change the channel, press the 'CH' button on the transmitter. The channel indicator lights will show the currently selected channel. Ensure the transmitter and receiver are set to the same channel for proper operation. This flexibility helps prevent interference in complex wireless environments.
3.3 Pairing
The U7 system typically pairs automatically when both the transmitter and receiver are powered on and set to the same channel. If pairing does not occur, ensure both units are within range (up to 90 ft) and try cycling the power on both devices.
3.4 Usage Tips
- For optimal wireless performance, maintain a clear line of sight between the transmitter and receiver.
- Avoid placing the receiver near other 2.4 GHz wireless devices to minimize potential interference.
- Regularly check battery levels to prevent interruptions during performances.
- Use the included fur or foam windscreens to reduce wind noise in outdoor or high-airflow environments.
