Configuració
Controls del panell frontal
Figura 2: Panell frontalview
- Interruptor d'alimentació: Located on the front panel to turn the amplificador ON o OFF.
- Channel Level Controls: Independent rotary knobs for adjusting the output level of Channel 1 and Channel 2.
- Indicadors LED: Signal, Clip, Protect, and Bridge LEDs provide visual feedback on the amplifier's status.
Connexions del panell posterior
Figura 3: Connexions del panell posterior
- Connectors d'entrada: XLR and 1/4" (6.5mm Jack) balanced inputs for Channel 1 and Channel 2.
- Connectors de sortida: 3 Speakon outputs for Channel A, Channel B, and Bridged mode. 5-Way binding banana plug outputs are also available.
- Interruptor de mode: Selects between Stereo, Parallel, and Bridged operating modes.
- Interruptor de creuament: Selects between Bypass (full range), Sub 160Hz, and Sub 80Hz for low-pass filtering.
- Interruptor d'elevació de terra: Helps eliminate hum and noise caused by ground loops.
- Entrada d'alimentació: Connecteu aquí el cable d'alimentació de CA inclòs.
Connexió del sistema
- Apagar: Assegureu-vos el ampL'amplificador estigui apagat abans de fer cap connexió.
- Connexions d'entrada: Connect your audio source (e.g., mixer, DJ controller) to the XLR or 1/4" inputs on the rear panel. Use balanced cables for optimal performance.
- Connexions de sortida: Connect your passive loudspeakers to the Speakon or 5-Way binding banana plug outputs. Ensure correct polarity (+ to + and - to -).
- Selecció del mode: Use the Mode switch to select your desired operating mode (Stereo, Parallel, or Bridged).
- Crossover Setting: Adjust the Crossover switch based on your speaker setup (Bypass for full-range speakers, Sub 160Hz or Sub 80Hz for subwoofers).
- Encès: Once all connections are secure, turn the amplifier ON using the front panel power switch.
En funcionament
Funcionament del panell frontal
- Ajust de volum: Use the Channel 1 and Channel 2 level controls to set the desired output volume for each channel.
- Estat de seguiment: Observeu els indicadors LED:
- LED de senyal: S'il·lumina quan hi ha un senyal d'àudio.
- LED de clip: Illuminates when the input signal is too high, causing clipping or distortion. Reduce the input level from your source or the amplifier's channel level.
- Protegir el LED: S'il·lumina si el amplifier detects a fault (e.g., short circuit, overheating) and activates protection mode.
- Bridge LED: S'il·lumina quan el amplifier is operating in Bridged mode.
Modes de funcionament
- Mode estèreo: Each channel operates independently, providing separate left and right audio signals. Ideal for standard stereo setups.
- Mode paral·lel: Both channels receive the same input signal but operate independently. Useful for driving multiple speakers with a mono signal.
- Mode pont: Combines the power of both channels into a single, higher-power output. Typically used for driving a single, high-power subwoofer.
Funcionalitat creuada
- Bypass: Sends a full-range audio signal to the outputs. Suitable for main speakers.
- Sub 160Hz / Sub 80Hz: Activates a low-pass filter, allowing only frequencies below 160Hz or 80Hz (respectively) to pass through. Essential when driving subwoofers to prevent higher frequencies from reaching them.
Manteniment
- Neteja: Netegeu regularment l'exterior de la amplifier with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Ventilació: Ensure the front and rear ventilation openings are clear of dust and obstructions to maintain proper airflow and prevent overheating. The variable speed cooling fan helps regulate internal temperature.
- Substitució de fusibles: Si el amplifier does not power on, check the fuse located near the AC power input on the rear panel. Replace with a fuse of the same type and rating (refer to specifications for details).
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense poder | Power cable disconnected, blown fuse | Check power cable connection, replace fuse if necessary. |
| Sense sortida de so | Incorrect input/output connections, low volume, Protect LED on | Verify all cable connections, increase channel level, check for faults if Protect LED is on. |
| So distorsionat | Input signal too high (Clipping), faulty cables, speaker impedance mismatch | Reduce input level (Clip LED off), check/replace cables, ensure speaker impedance matches ampcapacitats del lificador. |
| Brunzit/Soroll | Ground loop, faulty cables | Activate Ground Lift switch, use balanced cables, check/replace cables. |
| Protect LED on | Overheating, short circuit, DC output protection | Turn off unit, check speaker connections for shorts, ensure adequate ventilation. Allow unit to cool down. |
