4.1 Frontpanelfunktioner
- Power knap: Drejer amplifter tænd/sluk.
- Channel Indicators (1-4):
- CLIP/MUTE: Illuminates when the output signal is clipping or when the channel is muted.
- SIGNAL: Lyser, når der er et lydsignal.
- STRØM: Indicates output current status.
- BESKYTTE: Illuminates when the protection circuit is active.
- MIDLERTIDIG: Lyser, når amplifier is overheating.
4.2 Bagpanelfunktioner
- DIP-switchindstillinger: 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.
- Højttalerudgange: Connects to loudspeakers. Supports various wiring configurations including bridged mode.
- Remote DC Level: Ports for remote control of channel levels.
- AC strømindtag: Standard IEC power connector for AC power cord.
5. Opsætning
Follow these steps to set up your Ashly nX1504 amplivligere:
- Rack montering: Monter sikkert amplifier in a standard 19-inch equipment rack using appropriate rack screws. Ensure sufficient space for ventilation.
- Indgangsforbindelser: Tilslut din lydkilde (mixer, forforstærker)amplifier, etc.) to the input connectors (CH1-CH4) on the rear panel using balanced XLR or TRS cables.
- Højttalerforbindelser: 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.
- DIP-switchkonfiguration: 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.
- Strømtilslutning: 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.
- Første gang tændt: 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. Betjeningsvejledning
Når 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.
- Overvågningsindikatorer: 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.
- Brokoblet tilstand: 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).
- Sluk: Always power down the amplifier after use by pressing the front panel power button.
7. Vedligeholdelse
Proper maintenance ensures the longevity and reliable performance of your amplivligere:
- Rensning: Rengør regelmæssigt ydersiden af amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free of dust and debris.
- Ventilation: Periodically check that the ventilation openings are not obstructed. Dust accumulation can lead to overheating.
- Forbindelser: Periodically check all input and output connections for secure fit. Loose connections can cause signal loss or intermittent operation.
- Opbevaring: Hvis du opbevarer amplifier for an extended period, ensure it is in a dry, cool environment, protected from dust and extreme temperatures.
8. Fejlfinding
Se tabellen nedenfor for almindelige problemer og løsninger på disse:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Power cord disconnected; Power outlet failure; Internal fuse blown | Check power cord connection; Test power outlet; Contact qualified service personnel for fuse replacement. |
| Ingen lydudgang | 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. |
