The DI-2.4000 is a 4-channel digital amplifier manufactured in Germany. The DSP amplifiers developed and manufactured by Fohhn offer high power density and excellent sound. The amplifiers are designed for mobile sound systems and fixed installations. They provide all essential functionalities and almost unlimited connectivity in terms of audio inputs. Whether AES/EBU, Dante or Analogue – they offer maximum flexibility through interchangeable connection modules. The corresponding speaker presets ensure optimal performance and reliability.
Digital audio everywhere
Almost all Fohhn devices are equipped with transformer-balanced digital AES/EBU inputs (AES-3 standard). As AES/EBU is a common standard format, all digital audio networks have AES/EBU interfaces. Fohhn thus enables maximum connectivity for fully digital and interference-free transmission of audio signals.
