6. Persediaan
6.1 Penempatan
Kedudukan yang amplifier in a location that allows for proper ventilation. Avoid enclosed spaces or stacking other heat-generating equipment directly on top of the unit. Ensure the surface is stable and can support the ampberat pengalir.
6.2 Sambungan Kuasa
- Sahkan PILIHAN KUASA suis pada panel belakang ditetapkan kepada volum yang betultage (110V or 220V) for your electrical supply.
- Connect the supplied AC power cable to the INPUT AC on the rear panel and then to a grounded electrical outlet.
6.3 Sambungan Input
Sambungkan sumber audio anda (pengadun, pra-amplifier, etc.) to the INPUT jacks (XLR or 1/4" TRS) on the rear panel. Use high-quality shielded cables to minimize noise.
6.4 Output Connections (Speakers)
Sambungkan pembesar suara anda ke OUTPUT terminals (Speakon or Binding Post) on the rear panel. Ensure correct polarity (+ to + and - to -) for all connections. Match speaker impedance to ampkeupayaan pencair.
6.5 Pemilihan Mod
Tetapkan MODE switch on the rear panel according to your desired configuration:
- STEREO: For typical two-channel operation, with independent signals for Channel A and Channel B.
- JAMBATAN: For combining both channels into a single, higher-power mono output. Connect the speaker to the designated bridge output terminals (refer to markings on the unit).
- ROTI: For parallel input to both channels, with independent outputs. Both channels receive the same input signal.
7. Arahan Operasi
- Ensure all connections (power, input, output) are secure and correct.
- Menolak CH-A dan CH-B Level Controls on the front panel to their minimum (MIN) position.
- Tekan ke KUASA butang untuk menghidupkan amplifier. The power indicator will illuminate.
- If desired, insert the key into the KUNCI switch and turn it to the 'ON' position to enable ampfungsi penguat.
- Mula memainkan audio daripada peranti sumber anda.
- Perlahan-lahan tingkatkan CH-A dan CH-B Level Controls untuk mencapai volum yang dikehendaki.
- Pantau Meter LED to observe output levels and the CLIP Indicators to prevent distortion. If a CLIP indicator flashes frequently, reduce the input level from your source or the amplifier's level control.
- Untuk mematikan amplifier, first reduce the level controls to minimum, then press the KUASA butang.
8. Penyelenggaraan
- Pembersihan: Putuskan sambungan amplifier from power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Pengudaraan: Regularly check that the ventilation grilles are free from dust and obstructions. Dust accumulation can lead to overheating.
- Sambungan: Periodically check all cable connections for tightness and wear.
9. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada kuasa | Power cable disconnected; Power switch off; Incorrect voltage selection; Blown fuse; Lock switch engaged. | Check power cable connection; Ensure power switch is ON; Verify 110V/220V switch setting; Check/replace fuse (by qualified personnel); Disengage lock switch with key. |
| Tiada keluaran bunyi | Input cables disconnected; Speaker cables disconnected/incorrectly wired; Input source not playing; Amplifier level controls at minimum; Incorrect mode selection. | Check all input and output cable connections; Ensure input source is active; Increase amplifier level controls; Verify MODE switch setting. |
| Bunyi herot | Input signal too high (clipping); Speaker impedance mismatch; Damaged speaker. | Reduce input level from source or amplifier level controls; Ensure speaker impedance is compatible; Test with different speakers. |
