7。 トラブルシューティング
If you encounter issues with your PB23, refer to the following table for common problems and their solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| No power indicator light (pwr LED off) | 電源アダプタが接続されていないか故障しています。コンセントがアクティブではありません。 | Ensure power adapter is securely connected to the PB23 and a working electrical outlet. Test the outlet with another device. |
| マイクから音が出ない | Incorrect connections; faulty microphone or cables; mixer input issues. | Verify all XLR cables are correctly connected (Mic to PB23 Input, PB23 Output to Mixer Input). Test microphone and cables with another setup if possible. Check mixer input settings. |
| ハミング音またはブザー音 | グランドループ、不良ケーブル、干渉。 | Ensure all equipment is properly grounded. Try different XLR cables. Move the PB23 away from other electronic devices that might cause interference. |
| Weak or distorted signal | Microphone not receiving full phantom power; faulty microphone. | Confirm the pwr LED is on. Test with a different condenser microphone if available to rule out microphone issues. |
