Ashly CA502 2-Channel 500W Class D Ampلايف

1. پیژندنه

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.

• ان پټ نښلونکي: Use the balanced Euroblock or XLR Combo input connectors for audio signal input.
• د سپیکر محصولات: 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.
• د DIP سویچ تنظیمات: 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 د بریښنا نښلول

ورکړل شوی AC بریښنا تار سره وصل کړئ amplifier's power inlet and then to a grounded AC power outlet. The amplifier operates on 100-240VAC, 50/60Hz.

4.1 د فرنټ پینل کنټرولونه او شاخصونه

• د ننوتلو کچې کنټرولونه: د هر چینل لپاره د ننوتلو حساسیت تنظیم کړئ.
• د LED شاخصونه:
  • 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): روښانه کوي که چیرې amplifier enters protection mode due to an issue.
  • Current (Yellow): Indicates high current draw.
  • Temp (Yellow): Indicates high internal temperature.
  • Bridge (Green): روښانه کوي کله چې د 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:

• د ننوتو لاسته راوړنه: Adjusts the input gain for the channel.
• Output Clip Limiter: Engages or disengages the output clip limiter.
• د لوړ پاس فلټر (HPF): Activates an 80Hz high-pass filter to protect smaller speakers.
• Standby Polarity: Configures the standby control input polarity.
