Ashly CA502 2-Channel 500W Class D Ampmás vivaz

1. Introducción

The Ashly CA502 is a 2-channel Class D power amplifier designed for professional audio installations. It delivers 500W per channel into 2 or 4 Ohms, and 250W into 8 Ohms. When bridged, it can provide 1000W into 4 Ohms or drive 70V/100V loads. This amplifier incorporates Ashly's proprietary D-MAX technology, featuring ultra-fast Silicone-Carbide switches, a high-speed power supply, and Dynamic Power Factor Correction for exceptional efficiency and stable performance. The SailFlow directed cooling system ensures optimal thermal management, allowing the amplifier to operate reliably even under demanding conditions.

Key features include front-panel input level controls, LED indicators for amplifier status, balanced Euroblock and XLR combo input connectors, VCA control ports, and switchable High-Pass Filters (HPF) and Limiters on each channel. A standby port and front panel lockout provide additional flexibility and security.

3. Configuración

3.1 Instalación física

The Ashly CA502 is designed for rack mounting. It occupies 2U of rack space. Ensure sufficient space for ventilation, especially at the front and rear of the unit.

• Montar el ampfije el dispositivo de forma segura en un rack de equipos estándar de 19 pulgadas utilizando los tornillos de rack adecuados.
• Deje al menos 1U de espacio vacío por encima y por debajo del ampLificador para un flujo de aire óptimo, especialmente en racks cerrados.

3.2 Conexiones del panel posterior

The rear panel provides all necessary input, output, and control connections. Refer to Figure 2 for a visual guide.

Figure 2: Rear panel of the Ashly CA502 amplifier, detailing connection points.

• Conectores de entrada: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
• Salidas de altavoz: Connect your speakers to the Euroblock speaker output terminals. Ensure correct polarity and impedance matching.
• VCA Control Ports: For remote volume control, connect a standard volume control device (e.g., Ashly WR-1.1) to the VCA control ports.
• Standby Port: Connect external control systems for amplifier standby functionality.
• Configuración del interruptor DIP: Configure per-channel settings such as Limiter and High-Pass Filter using the DIP switches. Refer to the 'Operation' section for detailed settings.

3.3 Conexión de alimentación

Conecte el cable de alimentación de CA suministrado a la amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4. Operación

4.1 Controles e indicadores del panel frontal

• Controles de nivel de entrada: Ajuste la sensibilidad de entrada para cada canal.
• Indicadores LED:
  • Clip/Mute (Red): Illuminates when the output signal is clipping or the channel is muted.
  • Señal (Verde): Indicates the presence of an input signal.
  • Protect (Red): Se ilumina si el amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): Se ilumina cuando el amplifier is operating in bridged mode.

4.2 Rear Panel DIP Switch Settings

The DIP switches on the rear panel allow for per-channel configuration of various functions:

• Ganancia de entrada: Adjusts the input gain for the channel.
• Output Clip Limiter: Engages or disengages the output clip limiter.
• Filtro de paso alto (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
• Bloqueo del panel frontal: Enables or disables the front panel controls.

4.3 Bridged Mode and 70V/100V Operation

The CA502 can be configured for bridged operation to combine the power of both channels into a single, higher-power output. This is also used for driving 70V or 100V constant voltagsistemas de altavoces electrónicos.

• To engage bridged mode, refer to the DIP switch settings on the rear panel and the wiring diagram provided on the unit.
• For 70V/100V applications, ensure the amplifier is correctly configured and wired for constant voltage output. The CA502 model requires bridging to achieve 70V output.

5. Mantenimiento

Regular maintenance ensures the longevity and optimal performance of your Ashly CA502 ampmás duradero.

5.1 Limpieza

• Desconectar el amplifier from the power source before cleaning.
• Utilice un paño suave y seco para limpiar el exterior de la unidad.
• Periodically use a vacuum cleaner with a brush attachment to remove dust from the ventilation grilles.
• No utilice limpiadores líquidos ni disolventes, ya que pueden dañar el acabado o los componentes internos.

5.2 Sistema de enfriamiento

The CA Series amplifiers feature a SailFlow directed cooling system designed for efficient heat dissipation. This system helps the amplifier run cool and quietly.

Figure 3: SailFlow directed cooling system diagram, showing efficient airflow.

• Asegúrese de que el amplifier's ventilation openings are never obstructed.
• Maintain proper rack ventilation to prevent heat buildup, which can affect performance and lifespan.

6. Solución de problemas

If you encounter issues with your Ashly CA502 amplifier, consult the following basic troubleshooting steps:

• Sin energía:
  • Compruebe que el cable de alimentación esté conectado de forma segura a ambos amplifier and a live AC outlet.
  • Verify the AC outlet is functioning by plugging in another device.
• Sin salida de audio:
  • Ensure all input and output cables are correctly connected and secure.
  • Check the input level controls on the front panel are not set to minimum.
