4.1 Característiques del panell frontal
- Botó d'encesa: Gira el ampactivador/desactivat.
- Channel Indicators (1-4):
- CLIP/MUTE: Illuminates when the output signal is clipping or when the channel is muted.
- SENYAL: S'il·lumina quan hi ha un senyal d'àudio.
- ACTUAL: Indicates output current status.
- PROTEGEIX: Illuminates when the protection circuit is active.
- TEMP: S'il·lumina quan el ampel lifter s'està sobreescalfant.
4.2 Característiques del panell posterior
- Configuració del commutador 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.
- Sortides dels altaveus: Connects to loudspeakers. Supports various wiring configurations including bridged mode.
- Remote DC Level: Ports for remote control of channel levels.
- Entrada d'alimentació CA: Standard IEC power connector for AC power cord.
5. Configuració
Follow these steps to set up your Ashly nX1504 ampmés viu:
- Muntatge en bastidor: Munteu de manera segura el amplifier in a standard 19-inch equipment rack using appropriate rack screws. Ensure sufficient space for ventilation.
- Connexions d'entrada: Connecteu la font d'àudio (mesclador, preamplificador)amplifier, etc.) to the input connectors (CH1-CH4) on the rear panel using balanced XLR or TRS cables.
- Connexions d'altaveus: 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.
- Configuració de l'interruptor 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.
- Connexió d'alimentació: 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.
- Encesa inicial: 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. Instruccions de funcionament
Un cop el 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.
- Indicadors de seguiment: 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.
- Mode pont: 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).
- S'apagui: Always power down the amplifier after use by pressing the front panel power button.
7. Manteniment
Proper maintenance ensures the longevity and reliable performance of your ampmés viu:
- Neteja: Netegeu regularment l'exterior de la amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free of dust and debris.
- Ventilació: Periodically check that the ventilation openings are not obstructed. Dust accumulation can lead to overheating.
- Connexions: Periodically check all input and output connections for secure fit. Loose connections can cause signal loss or intermittent operation.
- Emmagatzematge: Si emmagatzema el amplificador durant un període prolongat, assegureu-vos que estigui en un entorn sec i fresc, protegit de la pols i de les temperatures extremes.
