4. Configuració i connexions
Follow these steps to set up your Vonyx VXA-800 ampmés viu:
- Col·locació: Col·loca el amplifier in a well-ventilated area, preferably in a 19-inch rack (3U space required). Ensure sufficient space for airflow around the unit.
- Connexions d'entrada:
- Connecteu la font d'àudio (mesclador, pre-amplifier, etc.) to the RCA or 6.3mm Jack inputs on the rear panel.
- For stereo operation, connect the left channel of your source to CH1 input and the right channel to CH2 input.
- Output Connections (Speakers):
- Connect your speakers to the appropriate output terminals (NL2, 6.3mm Jack, or screw terminals).
- Ensure speaker impedance is within the amplifier's specified range (minimum 4 Ohms per channel in stereo mode).
- For bridge mode, connect the speaker to the designated bridge output terminals and ensure the mode switch is set to "Bridge".
- Selecció del mode: Use the "MODE" switch on the rear panel to select the desired operating mode:
- ESTÉREO: Each channel operates independently.
- PONT: Combines both channels for a single, higher power output (mono).
- Connexió d'alimentació: Connecteu el cable d'alimentació a la xarxa amplifier's power inlet and then to a suitable mains power outlet (230V AC, 50Hz).
- Encesa inicial: Abans d'encendre el amplifier, ensure all volume controls are set to minimum. Then, switch on the amplifier using the front panel power switch.
5. Instruccions de funcionament
Un cop el amplifier is properly connected, follow these steps for operation:
- Encès: Ensure all connections are secure and turn on the amplifier using the front panel power switch. The power LED should illuminate.
- Ajust de volum: Slowly increase the volume controls for Channel 1 and Channel 2 to the desired listening level.
- Monitoring LEDs:
- LED DE SENYAL: S'il·lumina quan hi ha un senyal d'àudio.
- LED CLIP: Illuminates when the input signal is too high, causing distortion. Reduce the input level from your source or the amplifier's volume controls to prevent clipping.
- LED DE PROTECCIÓ: S'il·lumina si el amplifier enters protection mode due to overheating, short circuit, or DC offset. Turn off the amplifier, check connections, and allow it to cool down before restarting.
- Ascensor de terra: If you experience hum or buzzing, try flipping the "GROUND LIFT" switch on the rear panel to isolate the audio ground from the chassis ground.
- Apagar: Before powering off, reduce all volume controls to minimum. Then, switch off the ampmés viu.
6. Manteniment
Un manteniment adequat garanteix la longevitat i el rendiment òptim del vostre ampmés viu.
- Neteja: Feu servir un drap suau i sec per netejar l'exterior de la unitat. No utilitzeu productes de neteja abrasius ni dissolvents.
- Ventilació: Regularly check that the ventilation openings are clear of dust and debris. Blocked vents can lead to overheating.
- Emmagatzematge: Si emmagatzema el amplifier for an extended period, ensure it is in a dry, dust-free environment.
- Manteniment: All internal servicing should be performed by qualified service personnel only.
