- Channel Indicators (1-4):
- CLIP/MUTE: Illuminates when the output signal is clipping or when the channel is muted.
- ISIGABA: Illuminates when an audio signal is present.
- AMANJE: Indicates output current status.
- VIKELA: Illuminates when the protection circuit is active.
- ISIKHATHI: Ikhanyisa uma i amplifier is overheating.
4.2 Izici zephaneli yangemuva
- Izilungiselelo Zokushintsha kwe-DIP: Configures various amplifier parameters such as gain, HPF, and bridging. Refer to the detailed setup section for specific configurations.
- Input Connectors (CH1-CH4): Balanced input connections for audio signals.
- Imiphumela Yesipikha: Connects to loudspeakers. Supports various wiring configurations including bridged mode.
- Remote DC Level: Ports for remote control of channel levels.
- I-AC Power Inlet: Standard IEC power connector for AC power cord.
5. Setha
Follow these steps to set up your Ashly nX1504 ampophilayo:
- Ukukhweza ama-Rack: Faka ngokuphephile i- amplifier in a standard 19-inch equipment rack using appropriate rack screws. Ensure sufficient space for ventilation.
- Okokufaka ukuxhumana: Xhuma umthombo wakho womsindo (i-mixer, i-preamplifier, etc.) to the input connectors (CH1-CH4) on the rear panel using balanced XLR or TRS cables.
- Izixhumanisi zesipika: Connect your loudspeakers to the speaker output terminals. Pay close attention to polarity (+/-) and impedance matching. For bridged operation, consult the rear panel diagram and DIP switch settings.
- Ukucushwa kokushintsha kwe-DIP: Before powering on, configure the DIP switches on the rear panel according to your system requirements (e.g., input gain, high-pass filter, bridging). Refer to the diagram on the rear panel for specific switch functions.
- Ukuxhuma kwamandla: Connect the supplied AC power cord to the AC power inlet on the rear panel, then plug the other end into a grounded power outlet.
- Amandla Okuqala Avuliwe: Ensure all connections are secure and correct. Turn on the amplifier using the front panel power button. Observe the indicator lights for normal operation.
6. Iziqondiso Zokusebenza
Once the amplifier is set up, follow these guidelines for operation:
- Gain Structure: Adjust the input gain on your source device and the amplifier's input sensitivity (via DIP switches) to achieve optimal signal-to-noise ratio without clipping. The SIGNAL indicator should illuminate consistently, and the CLIP/MUTE indicator should only flash momentarily during peak signals, if at all.
- Izinkomba Zokuqapha: Regularly monitor the front panel indicators:
- CLIP/MUTE: If this light is constantly on, reduce the input level to prevent distortion and potential speaker damage.
- PROTECT/TEMP: If these lights illuminate, the amplifier is in protection mode or overheating. Turn off the unit, allow it to cool, and check for proper ventilation or speaker impedance issues.
- Imodi Yebhuloho: If operating in bridged mode, ensure the correct DIP switch settings are applied and that the speaker impedance is suitable for bridged operation (typically higher impedance than stereo mode).
- Amandla Phansi: Always power down the amplifier after use by pressing the front panel power button.
7. Isondlo
Proper maintenance ensures the longevity and reliable performance of your ampophilayo:
- Ukuhlanza: Hlanza ingaphandle le- amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free of dust and debris.
- Ukungenisa umoya: Periodically check that the ventilation openings are not obstructed. Dust accumulation can lead to overheating.
- Izixhumanisi: Periodically check all input and output connections for secure fit. Loose connections can cause signal loss or intermittent operation.
- Isitoreji: Uma ugcina i- amplifier for an extended period, ensure it is in a dry, cool environment, protected from dust and extreme temperatures.
8. Ukuxazulula izinkinga
Bheka ithebula elingezansi ngezinkinga ezivamile nezisombululo zazo:
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| Awekho amandla | Power cord disconnected; Power outlet failure; Internal fuse blown | Check power cord connection; Test power outlet; Contact qualified service personnel for fuse replacement. |
| Akukho okukhipha umsindo | Input cables disconnected; Speaker cables disconnected/incorrectly wired; Amplifier muted; Source device issue | Check all input and speaker connections; Ensure amplifier is not muted; Verify source device is sending signal. |
