Ashly CA502 2-Channel 500W Class D Ampmés viu

1. Introducció

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.

• Manteniment: No intenteu atendre aquest producte vosaltres mateixos. Consulteu tots els serveis a personal de servei qualificat.
• cables: Eviteu que el cable d'alimentació sigui trepitjat o pessigat, especialment als endolls, els endolls i el punt on surten de l'aparell.

3. Configuració

3.1 Instal·lació 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.

• Muntar el ampFixeu el lifer de forma segura en un rack d'equips estàndard de 19 polzades amb els cargols de rack adequats.
• Deixeu com a mínim 1U d'espai buit per sobre i per sota del ampLifter per a un flux d'aire òptim, especialment en bastidors tancats.

3.2 Connexions del panell 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.

• Connectors d'entrada: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
• Sortides dels altaveus: 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.
• Configuració del commutador 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 Connexió d'alimentació

Connecteu el cable d'alimentació de CA subministrat a amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4. Funcionament

4.1 Controls i indicadors del tauler frontal

• Input Level Controls: Ajusteu la sensibilitat d'entrada per a cada canal.
• Indicadors LED:
  • Clip/Mute (Red): Illuminates when the output signal is clipping or the channel is muted.
  • Signal (Green): Indicates the presence of an input signal.
  • Protect (Red): S'il·lumina si el amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): S'il·lumina quan 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:

• Guany d'entrada: Adjusts the input gain for the channel.
• Output Clip Limiter: Engages or disengages the output clip limiter.
• Filtre de pas alt (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
• Bloqueig del panell 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. Manteniment

Regular maintenance ensures the longevity and optimal performance of your Ashly CA502 ampmés viu.

5.1 Neteja

• Desconnecteu el amplifier from the power source before cleaning.
• Feu servir un drap suau i sec per netejar l'exterior de la unitat.
• Periodically use a vacuum cleaner with a brush attachment to remove dust from the ventilation grilles.
• No utilitzeu netejadors líquids ni dissolvents, ja que poden danyar l'acabat o els components interns.

5.2 Sistema de refrigeració

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.

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