The AIREA system components

<--- Picture Gallery



The AM-50 AIREA Master module is equipped with digital AES/EBU inputs and forms the main link to any digital mixing console, matrix, external sound source or digital audio network. 2U, Power Supply. Central interface with 8 x AES/EBU and Fohhn-Net inputs, plus 8 x digital outputs and power supply for up to 32 AIREA active loudspeakers.



Today’s sound systems are not only expected to deliver perfect audio results. They also need to be simple and flexible to install, compact and elegant in appearance, with high levels of performance capability. Most importantly, they also need to accommodate a digital signal input in order to be networked and remotely controlled. These demands have inspired Fohhn engineers to re-evaluate the current state of audio technology and to follow new and innovative paths of development.

Active loudspeaker concept. Digital Audio Networking Capability.
AIREA is an intelligent, active loudspeaker concept combined with versatile, digital audio networking capabilities. The system has been specially developed for high quality, flexible, forward-looking sound reinforcement applications. The AIREA system consists of state-of-the-art loudspeakers with integrated digital amplifiers and DSP technology, as well as a master module with digital inputs and outputs. Components are linked together via a conventional network cable.

A whole range of applications:
AV-Integration, Iosono 3D-Sound, Broadcast, TV-Studios, Shops, Conference rooms, Theaters, Rental, Churches, Hotels, Bars, Restaurants, High-End Home-Audio and more.
