6. Configuració
6.1 Col·locació
Col·loca el 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 amppes del vidador.
6.2 Connexió d'alimentació
- Verifiqueu el SELECCIÓ DE POTÈNCIA switch on the rear panel is set to the correct voltage (110V or 220V) for your electrical supply.
- Connect the supplied AC power cable to the ENTRADA CA on the rear panel and then to a grounded electrical outlet.
6.3 Connexions d'entrada
Connecteu la font d'àudio (mesclador, preamplificador)amplificador, etc.) a la ENTRADA jacks (XLR or 1/4" TRS) on the rear panel. Use high-quality shielded cables to minimize noise.
6.4 Output Connections (Speakers)
Connecteu els vostres altaveus al SORTIDA terminals (Speakon or Binding Post) on the rear panel. Ensure correct polarity (+ to + and - to -) for all connections. Match speaker impedance to amplifier capabilities.
6.5 Selecció del mode
Estableix el MODE switch on the rear panel according to your desired configuration:
- ESTÉREO: For typical two-channel operation, with independent signals for Channel A and Channel B.
- PONT: 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).
- MONO: For parallel input to both channels, with independent outputs. Both channels receive the same input signal.
7. Instruccions de funcionament
- Ensure all connections (power, input, output) are secure and correct.
- Baixeu el CH-A i CH-B Level Controls on the front panel to their minimum (MIN) position.
- Premeu el botó PODER botó per encendre el amplifier. The power indicator will illuminate.
- If desired, insert the key into the BLOC switch and turn it to the 'ON' position to enable ampfuncions de lificació.
- Comença a reproduir àudio des del dispositiu font.
- Augmenta lentament el CH-A i CH-B Level Controls per aconseguir el volum desitjat.
- Monitoritzar el Mesuradors 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.
- Per apagar el amplifier, first reduce the level controls to minimum, then press the PODER botó.
8. Manteniment
- Neteja: Desconnecteu el amplifier from power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Ventilació: Regularly check that the ventilation grilles are free from dust and obstructions. Dust accumulation can lead to overheating.
- Connexions: Periodically check all cable connections for tightness and wear.
