Ashly CA502 2-Channel 500W Class D Amppiù vivace

1. Introduzione

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. Informazioni sulla sicurezza

Si prega di leggere attentamente tutte le istruzioni di sicurezza prima di utilizzare questo dispositivo. Conservare il presente manuale per riferimento futuro.

• Fonte di energia: Collegare il amplifier only to a power supply of the type specified in this manual and on the unit.
• Messa a terra: Assicurare il amplifier is properly grounded to prevent electric shock.
• Ventilazione: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. Maintain adequate airflow around the unit.
• Acqua e umidità: Non esporre questo apparecchio a pioggia o umidità. Non utilizzare questo apparecchio vicino all'acqua.
• Calore: Non installare vicino a fonti di calore come radiatori, bocchette di riscaldamento, stufe o altri apparecchi (inclusi amplificatori) che producono calore.
• Manutenzione: Non tentare di riparare questo prodotto da soli. Affidare tutte le operazioni di manutenzione a personale di assistenza qualificato.
• cavi: Proteggere il cavo di alimentazione per evitare che venga calpestato o schiacciato, in particolare in corrispondenza delle spine, delle prese di corrente e del punto in cui esce dall'apparecchio.

3. Impostazione

3.1 Installazione fisica

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.

• Montare il 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 Collegamenti del pannello posteriore

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.

• Connettori di ingresso: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
• Uscite altoparlanti: 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.
• Impostazioni dell'interruttore 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 Collegamento di alimentazione

Collegare il cavo di alimentazione CA in dotazione al amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4. Funzionamento

4.1 Comandi e indicatori del pannello frontale

• Controlli del livello di ingresso: Regola la sensibilità di ingresso per ciascun canale.
• Indicatori LED:
  • Clip/Mute (Red): Illuminates when the output signal is clipping or the channel is muted.
  • Segnale (verde): Indicates the presence of an input signal.
  • Protect (Red): Si illumina se il amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): Si illumina quando il 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:

• Guadagno in ingresso: Adjusts the input gain for the channel.
• Output Clip Limiter: Engages or disengages the output clip limiter.
• Filtro passa-alto (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
• Blocco del pannello frontale: 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 voltagsistemi di altoparlanti.

• 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. Manutenzione

Regular maintenance ensures the longevity and optimal performance of your Ashly CA502 amppiù vivace.

5.1 Pulizia

• Scollegare il amplifier from the power source before cleaning.
• Utilizzare un panno morbido e asciutto per pulire la parte esterna dell'unità.
• Periodically use a vacuum cleaner with a brush attachment to remove dust from the ventilation grilles.
• Non utilizzare detergenti liquidi o solventi, poiché potrebbero danneggiare la finitura o i componenti interni.

5.2 Sistema di raffreddamento

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.

• Assicurarsi che il amplifier's ventilation openings are never obstructed.
• Maintain proper rack ventilation to prevent heat buildup, which can affect performance and lifespan.

6. Risoluzione Dei Problemi

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

• Nessun potere:
  • Verificare che il cavo di alimentazione sia collegato saldamente a entrambi i amplifier and a live AC outlet.
  • Verify the AC outlet is functioning by plugging in another device.
• Nessuna uscita 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.
  • Assicurare il amplifier is not in standby mode or muted.
• Audio distorto/clipping:
  • Reduce the input level to prevent the Clip/Mute LED from illuminating.
  • Ensure speakers are correctly matched to the ampimpedenza del condensatore.
  • Check for damaged speaker cables or faulty speakers.
• Overheating (Temp LED on):
  • Assicurare una ventilazione adeguata attorno all' amplifier. Clear any obstructions from the air vents.
  • Ridurre il livello di uscita o la durata del funzionamento ad alta potenza.
  • Verificare che l'impedenza dell'altoparlante sia compresa tra ampintervallo specificato dal lificatore.

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