1. The device does not power on. What should I check?

Please verify power cable connection, voltage supply and power switch status. If no indicator is on, test with another cable and socket.

2. There is input signal but no audio output.

Check input/output routing, mute status, gain settings and amplifier/speaker connections. Start with a basic preset for quick isolation.

3. The PC software cannot discover the device.

• Ensure the device and PC are in the same network segment.
• Check cables, switch status and firewall settings.
• Restart both the device and software, then scan again.

4. How can I reduce feedback on site?

Lower microphone gain first, adjust mic-speaker positioning, and apply feedback suppression plus EQ tuning when needed.

5. Why are parameter changes not taking effect?

Confirm that settings were applied/saved, and verify the active preset has not overwritten current values.

6. How do I update firmware or software?

Use files from Downloads and follow the release guide. Back up current presets before updating.

7. Is third-party control integration supported?

Yes. Open protocol integration is supported for third-party control platforms. Contact support for protocol documentation.

8. What information helps support respond faster?

• Product model and software version
