A-2 live Fohhn Digital Audio Interface

The A-2 live has been specially developed to enable a high-quality, trouble-free transfer of digital audio data from a computer to a professional sound reinforcement system.


AIREA Break Out Extension, Analogue interface for AIREA; Analogue and Fohhn-Net output for AIREA, AIREA-Net input, 2 x analogue and 1 x Fohhn-Net output.


AIREA 2 x 300W DSP amplifier module. AIREA-Net input, 2 x loudspeaker outputs

AIREA Cable for mobile applications

CAT-5 /AWG 24 network cable for mobile AIREA applications. Roadproof and tread-resistant. Black with Neutrik EtherCON connectors (RJ-45, metal housing).


flying- and mounting bracket, set of 2, ball impact resistant (for AS-06 ASX, AS-10 ASX, AS-22 ASX, AS-06, AS-10 and AS-22 as well as DLI-330 and DLI-430)

Ultra-compact, Active System Subwoofer with DSP and Long Excursion Chassis for use in a Digital Audio Network System

Compact, active system subwoofer with integrated 2-channel amplifier and DSP technology, equipped with a 12“ long excursion chassis with dual voice coil. With a capacity of up to 200 W, the sub can generate a maximum SPL of 119 dB.

The speaker’s high quality birch plywood housing is available as standard with a black textured paint finish. All classic RAL colours are optionally available. Other colour catalogues are also possible on request.

To protect the loudspeaker chassis and electronics the housing is fitted with a high grade, ball impact resistant, sound permeable front grille made from powder-coated steel. Six integrated M6 threaded inserts are designed to accommodate mounting brackets.

The subwoofer has been developed for dedicated use in a digital audio network system that includes active loudspeakers with integrated digital amplifiers and DSP technology, master modules and other system components

Connections: Input via RJ-45 (Neutrik etherCON) for digital AES/EBU signals, control signals and power supply. Output via RJ-45 link out (Neutrik etherCON) enables serial connection (Daisy Chain) to other system components.
