Ashly CA502 2-Channel 500W Class D Ampзадымнік

1. Уводзіны

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.

• Крыніца харчавання: Падключыце ampпадключайце прыладу толькі да крыніцы сілкавання тыпу, указанага ў гэтым кіраўніцтве і на ёй.
• Зазямленне: Забяспечце amplifier is properly grounded to prevent electric shock.
• Вентыляцыя: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. Maintain adequate airflow around the unit.
• Вада і вільгаць: Do not expose this apparatus to rain or moisture. Do not use this apparatus near water.
• Цяпло: Не ўстанаўлівайце побач з крыніцамі цяпла, такімі як радыятары, абагравальнікі, пліты або іншыя прылады (у тым ліку ampLifiers), якія вырабляюць цяпло.
• Абслугоўванне: Не спрабуйце самастойна абслугоўваць гэты прадукт. Звярніцеся да ўсіх абслугоўванняў кваліфікаванага абслуговага персаналу.
• Кабелі: Абараняйце сеткавы шнур ад наступання або заціскання, асабліва ў месцах вілкі, разеткі і месца выхаду з прылады.

3. Настройка

3.1 Фізічная ўстаноўка

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.

• Змантаваць 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 Злучэнні задняй панэлі

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.

• Уваходныя раздымы: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
• Выходы для дынамікаў: 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.
• Налады DIP-пераключальніка: 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 Падключэнне харчавання

Падключыце шнур харчавання пераменнага току, які ўваходзіць у камплект, да amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4. Аперацыя

4.1 Элементы кіравання і індыкатары на пярэдняй панэлі

• Input Level Controls: Адрэгулюйце ўваходную адчувальнасць для кожнага канала.
• Святлодыёдныя індыкатары:
  • 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): Illuminates if the amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): Загараецца, калі 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:

• Уваходнае ўзмацненне: Adjusts the input gain for the channel.
• Output Clip Limiter: Engages or disengages the output clip limiter.
• Фільтр высокіх частот (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
• Блакаванне пярэдняй панэлі: 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. Тэхнічнае абслугоўванне

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

5.1 Ачыстка

• Адключыце amplifier from the power source before cleaning.
• Use a soft, dry cloth to wipe down the exterior of the unit.
• 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 Сістэма астуджэння
