КСНУМКС. Решавање проблема
| Проблем | Могући узрок | Решење |
|---|---|---|
| No Power / Protect LED On | Blown fuse, poor power/ground connection, remote wire disconnected. | Check/replace fuse, verify power/ground connections, ensure remote wire is connected and receiving 12V. |
| Нема излаза звука | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Дистортед Соунд | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match amplifier's impedance rating. |
| AmpПрегревање усисивача | Недовољна вентилација, пренизак импеданс, продужена употреба велике количине звука. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
