The HADA-4B400 from Ecler is a high-power four-channel installation amplifier engineered for demanding professional audio applications. It delivers 4 x 400W at 4 ohms and can operate in bridge mode to provide 2 x 800W for high-impedance 70V/100V line systems, offering flexibility for both low- and high-impedance loudspeaker configurations within the same installation. The amplifier includes four analogue inputs on Euroblock connectors for secure and straightforward integration.

An internal matrix mixer and built-in signal processing provide flexible routing, level management, and system optimization without requiring external DSP hardware. The unit features four GPI ports for remote volume control and an external mute input for convenient day-to-day operation. Configuration and control are managed through HADA DSP Manager software, while third-party integration via TCP/IP ensures compatibility with centralized control systems.

The HADA-4B400 is well suited for leisure venues, hospitality environments, educational institutions, corporate facilities, and sports and wellness centers where reliable, high-output multi-channel amplification and flexible system control are essential.
