1. Įvadas
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.

3.1 Fizinis įrengimas
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.
- Sumontuokite 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 Galinio skydelio jungtys
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.
- Įvesties jungtys: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
- Garsiakalbių išvestys: 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.
- DIP jungiklio nustatymai: 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 Maitinimo jungtis
Prijunkite pridedamą kintamosios srovės maitinimo laidą prie amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.
4. Operacija
4.1 Priekinio skydelio valdikliai ir indikatoriai
- Įvesties lygio valdikliai: Sureguliuokite kiekvieno kanalo įvesties jautrumą.
- LED indikatoriai:
- 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): Šviečia, jei amplifier enters protection mode due to an issue.
- Current (Yellow): Indicates high current draw.
- Temp (Yellow): Indicates high internal temperature.
- Bridge (Green): Šviečia, kai 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:
- Įvesties padidėjimas: Adjusts the input gain for the channel.
- Output Clip Limiter: Engages or disengages the output clip limiter.
- Aukšto dažnio filtras (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
- Standby Polarity: Configures the standby control input polarity.
- Priekinio skydelio užraktas: 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.
