The A Professional Power Amplifier Series is designed for professional sound reinforcement applications requiring high output power, stable operation and excellent speaker control. Featuring three models from A204 to A208, the series provides output power ranging from 2×400W to 2×800W at 8Ω, making it suitable for a wide range of live events and commercial audio installations.
Built with high-current output stages and efficient cooling, the A Series delivers clean and dynamic audio while maintaining low distortion even at high output levels. The amplifiers support both stereo operation and bridge mono mode, allowing flexible system configuration for full-range speakers, monitor speakers and passive subwoofers.
With high damping factor, excellent signal-to-noise ratio and professional XLR/SpeakON connectivity, the A Series is an ideal choice for rental companies, performance venues, houses of worship, conference centers and touring productions.
For complete system integration, the A Series works perfectly with Stage Sound System and professional passive loudspeaker systems.
