4. Setup Guide
4.1 Charging the Devices
Before first use, fully charge the transmitter (TX) and receiver (RX) units using the provided USB-C charging cables. Connect the cables to a standard USB power adapter (not included) or a computer's USB port. The OLED display will indicate charging status.
4.2 Powering On/Off
- Power On: Long press the power button on both the TX and RX units until the OLED display illuminates.
- Power Off: Long press the power button again on both units until the display turns off.
4.3 Connecting to Recording Devices
The BY-XM6 S2 system is designed for plug-and-play operation. The TX and RX units will automatically pair upon powering on. If pairing fails, refer to the troubleshooting section.
- For Cameras (DSLR/Mirrorless): Use the 3.5mm TRS to TRS output cable. Connect one end to the RX's 'OUT' port and the other end to your camera's microphone input.
- For Smartphones/Tablets: Use the 3.5mm TRS to TRRS output cable. Connect one end to the RX's 'OUT' port and the other end to your smartphone's headphone/microphone jack. For devices without a 3.5mm jack, an appropriate adapter (e.g., USB-C to 3.5mm or Lightning to 3.5mm) may be required (not included).
- Connecting Lavalier Microphone: Plug the lavalier microphone into the 'MIC IN' port on the TX unit. Ensure it is securely connected.
5. Operating Instructions
5.1 Mute Function
To mute the transmitter, short press the mute button on the TX unit. A mute icon will appear on the OLED display. Short press again to unmute.
5.2 Gain Control
Adjust the audio input gain on the TX unit to optimize sound levels and prevent distortion. Use the '+' and '-' buttons to increase or decrease the gain. Monitor the audio level bar on the OLED display to ensure levels are within the optimal range.
5.3 Mono/Stereo Mode Selection
The receiver (RX) allows you to switch between mono and stereo output modes. Navigate through the menu on the RX unit to select the desired mode. In mono mode, both transmitter audio signals are mixed into a single channel. In stereo mode, each transmitter's audio is output to a separate channel (left/right).
5.4 Real-time Monitoring
Connect headphones to the 3.5mm headphone jack on the RX unit to monitor the audio in real-time. This allows you to check audio quality and levels during recording.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the units. Do not use harsh chemicals or abrasive materials.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Use the provided pouch for protection.
- Battery Care: For optimal battery life, avoid fully discharging the units frequently. Charge them regularly, even if not in use for extended periods.
- Windshields: Regularly clean or replace the fur windshields to maintain effective wind noise reduction.
7. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| No sound or low volume | Incorrect cable connection; low gain setting; muted transmitter; low battery. | Ensure cables are securely connected. Adjust gain on TX. Check if TX is muted. Charge units. |
| Voice breaks or signal dropouts | Obstacles between TX and RX; exceeding operating range; strong interference. | Reduce distance between TX and RX. Ensure clear line of sight. Avoid areas with strong Wi-Fi or other 2.4GHz devices. |
| Poor noise cancellation / Excessive background noise | Improper microphone placement; no windshield used; high ambient noise. | Ensure lavalier mic is placed correctly (e.g., 6-8 inches from mouth). Use the fur windshield, especially outdoors. Record in quieter environments. |
| Units not pairing | Units too far apart; interference; pairing error. | Bring TX and RX closer together. Power cycle both units. Refer to manual for manual pairing steps if auto-pairing fails. |
| OLED display not working | Low battery; unit not powered on; hardware issue. | Charge the unit. Long press power button to ensure it's on. If issue persists, contact support. |
