1. הקדמה
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.

- אַרייַנשרייַב קאַנעקטערז: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
- רעדנער אַוטפּוץ: 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.
- דיפּ סוויטש סעטטינגס: Configure per-channel settings such as Limiter and High-Pass Filter using the DIP switches. Refer to the 'Operation' section for detailed settings.

- Current (Yellow): Indicates high current draw.
- Temp (Yellow): Indicates high internal temperature.
- Bridge (Green): יללומאַנייץ ווען די 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:
- אַרייַנשרייַב געווינס: Adjusts the input gain for the channel.
- Output Clip Limiter: Engages or disengages the output clip limiter.
- הויך-פּאַס פילטער (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
- Standby Polarity: Configures the standby control input polarity.
- פראָנט פּאַנעל לאַק: 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.
