1. 서론
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.

4.1 전면 패널 컨트롤 및 표시기
- Input Level Controls: 각 채널의 입력 감도를 조정하십시오.
- LED 표시등:
- Clip/Mute (Red): Illuminates when the output signal is clipping or the channel is muted.
- 신호 (녹색): Indicates the presence of an input signal.
- Protect (Red): 만약 ~라면 밝혀줍니다 amplifier enters protection mode due to an issue.
- Current (Yellow): Indicates high current draw.
- Temp (Yellow): Indicates high internal temperature.
- Bridge (Green): 다음과 같은 경우에 켜집니다. 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:
- 입력 이득: Adjusts the input gain for the channel.
- Output Clip Limiter: Engages or disengages the output clip limiter.
- 하이패스 필터(HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
- Standby Polarity: Configures the standby control input polarity.
- 전면 패널 잠금: 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.
