Ashly CA502 2-Channel 500W Class D Ampmáis vivo

1. Introdución

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.

2. Información de seguridade

Please read and understand all safety instructions before operating this device. Retain this manual for future reference.

• Fonte de enerxía: Conecta o amplifier only to a power supply of the type specified in this manual and on the unit.
• Conexión a terra: Asegurar o amplifier is properly grounded to prevent electric shock.
• Ventilación: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. Maintain adequate airflow around the unit.
• Auga e humidade: Non expoña este aparello á choiva nin á humidade. Non o empregue preto da auga.
• Calor: Non instale preto de fontes de calor como radiadores, rexistros de calor, cociñas ou outros aparellos (incluíndo amplificadores) que producen calor.
• Servizo: Non intente atender este produto vostede mesmo. Remita todo o servizo a persoal de servizo cualificado.
• Cables: Protexa o cable de alimentación para evitar que se pise ou se pinche, especialmente nos enchufes, tomas de corrente e no punto de saída do aparello.

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.

• Monte o amplifier securely in a standard 19-inch equipment rack using appropriate rack screws.
• Allow at least 1U of empty space above and below the amplifier for optimal airflow, especially in enclosed racks.

3.2 Conexións do panel traseiro

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.
• Saídas de altofalantes: 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 do 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 o cable de alimentación CA subministrado ao amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4. Funcionamento

4.1 Controis e indicadores do panel frontal

• Input Level Controls: Axuste a sensibilidade de entrada para cada canal.
• Indicadores LED:
  • Clip/Mute (Red): Illuminates when the output signal is clipping or the channel is muted.
  • Sinal (verde): Indicates the presence of an input signal.
  • Protexer (vermello): Ilumínase se o amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): Ilumina cando o ampO lificador está a funcionar en modo ponteado.

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 paso alto (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
• Bloqueo do 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 voltage speaker systems.

• 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. Mantemento

Regular maintenance ensures the longevity and optimal performance of your Ashly CA502 ampmáis vivo.

5.1 Limpeza

• Desconecta o amplifier from the power source before cleaning.
• Use un pano suave e seco para limpar o exterior da unidade.
• Periodically use a vacuum cleaner with a brush attachment to remove dust from the ventilation grilles.
• Do not use liquid cleaners or solvents, as they may damage the finish or internal components.

5.2 Sistema de refrixeración

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

• Asegúrese de que o 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:

• Sen enerxía:
  • Check that the power cord is securely connected to both the amplifier and a live AC outlet.
  • Verify the AC outlet is functioning by plugging in another device.
• Sen saída 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.
  • Verify that the input source is active and sending a signal.
  • Check the speaker connections for correct polarity and secure contact.
  • Asegurar o amplifier is not in standby mode or muted.
• Distorted Audio / Clipping:
  • Reduce the input level to prevent the Clip/Mute LED from illuminating.
  • Ensure speakers are correctly matched to the amplifier's impedance.
  • Check for damaged speaker cables or faulty speakers.
• Overheating (Temp LED on):
  • Garantir unha ventilación adecuada ao redor amplifier. Clear any obstructions from the air vents.
  • Reduce the output level or the duration of high-power operation.
  • Verify speaker impedance is within the amplifier's specified range.

If the issue persists after performing these checks, contact Ashly technical support or a qualified service technician.
