AD 2U Class D Digital Power Amplifier Series

The AD 2U Class D Digital Power Amplifier Series is designed for professional sound reinforcement systems that require high continuous output, superior efficiency and long-term reliability. Featuring advanced Class D amplifier technology, Dual PFC switching power supply and a rugged 2U rack-mount chassis, the AD 2U Series delivers powerful performance while reducing energy consumption and operating weight.

Compared with conventional analog amplifiers, the AD 2U Series offers significantly higher efficiency, lower heat generation and improved portability. The amplifiers remain stable under demanding operating conditions and provide clean, dynamic audio for both mobile and permanent installations.

Available in four output configurations ranging from 2×600W to 2×1350W at 8Ω, the series supports 2Ω operation, making it suitable for driving multiple loudspeakers while maintaining excellent control and low distortion.

For complete sound reinforcement systems, the AD Series integrates perfectly with Stage Sound System and professional passive loudspeaker systems.
