Key Technologies

Class D High-Efficiency Amplification

The AD Series utilizes modern Class D amplifier architecture to achieve outstanding power efficiency while maintaining accurate audio reproduction. Compared with conventional amplifier designs, Class D technology significantly reduces heat generation and energy consumption.

Dual PFC Switching Power Supply

Dual PFC (Power Factor Correction) technology improves power conversion efficiency while maintaining stable output under different electrical conditions. It also minimizes power supply noise and improves amplifier reliability during continuous operation.

Wide Voltage Operation (90–265V)

The amplifier automatically adapts to different regional power supplies, making it suitable for international touring productions and export projects without requiring manual voltage switching.

Lightweight 1U Design

With only a 1U rack height, the amplifier occupies less rack space while reducing transportation weight, making it particularly attractive for rental companies and touring systems.

Advantages of Class D Technology

• Up to 40% lower power consumption

• Smaller and lighter chassis

• Lower heat generation

• Higher power density

• Lower operating costs

• Improved long-term reliability
