The Ashly CA-502 is a high-efficiency 2-channel power amplifier designed for professional audio, commercial sound, and demanding loudspeaker installations. It delivers up to 500 watts per channel at 2 or 4 ohms and 250 watts per channel at 8 ohms, while also supporting constant-voltage applications with 70V and 100V operation.
Powered by Ashly's D-MAX™ technology, the CA-502 is designed to deliver high output power while using electrical power efficiently. Its compact chassis, advanced cooling system, and flexible output configuration make it suitable for installations where amplifier performance, efficiency, and available electrical power are important considerations.
500W Per Channel Power
The CA-502 provides two amplifier channels with flexible low-impedance power ratings:
- 500W per channel at 2 ohms
- 500W per channel at 4 ohms
- 250W per channel at 8 ohms
- 1,000W bridged output
- 70V constant-voltage operation
This combination allows the CA-502 to power conventional low-impedance loudspeakers as well as commercial distributed audio systems.
High-Efficiency D-MAX™ Technology
Ashly's D-MAX™ technology is designed to maximize amplifier efficiency while delivering substantial output power. This makes the CA-502 particularly useful for installations where multiple amplifiers may need to operate from limited AC power.
The amplifier's efficient power architecture can help reduce the electrical and thermal demands associated with high-output amplification.
Designed for Heavy Loudspeaker Loads
The CA-502 is designed to remain stable with demanding speaker loads and can operate down to 0.2 ohms under supported configurations.
This low-impedance capability makes the amplifier useful for installations that require multiple loudspeakers to be powered from a single amplifier channel. Proper loudspeaker wiring and system configuration should always follow Ashly's installation and load requirements.
70V and 100V Commercial Audio
The CA Series can be used in constant-voltage commercial audio systems, including 70V and 100V installations.
This makes the CA-502 suitable for applications such as:
- Commercial paging systems
- Background music
- Distributed audio
- Retail sound systems
- Hospitality installations
- Performance spaces
- Large commercial facilities
- Multi-speaker installations
For 70V and 100V systems, the amplifier can provide the higher voltage output needed to distribute audio over longer cable runs and power multiple transformer-equipped loudspeakers.
Efficient Cooling with SailFlow™
The CA-502 incorporates Ashly's SailFlow™ cooling architecture to manage heat while keeping fan noise under control.
The cooling system is designed to provide reliable operation during demanding amplifier use without unnecessarily increasing acoustic noise in the installation environment.
Flexible Audio Connections
The CA-502 provides professional audio input connections for integration with mixers, DSP processors, signal processors, and other professional audio equipment.
Connection options include:
- Balanced XLR inputs
- Euroblock connections
- Professional speaker output connections
This allows the amplifier to be integrated into both conventional rack-mounted audio systems and commercial installed sound systems.
Compact Professional Amplifier
Despite its high output capability, the CA-502 uses a compact chassis designed for professional installations. Its efficient architecture allows substantial amplifier power without requiring the physical size and power consumption associated with many traditional high-power amplifier designs.
Applications
The Ashly CA-502 is well suited for:
- Commercial sound systems
- Professional installed audio
- Distributed 70V audio systems
- 100V commercial audio systems
