The new Fohhn Audio Interface.
Trouble-free, direct transmission of audio data from a computer to a professional sound reinforcement system, without any reduction in sound quality or level.

The A-1 live has been specially developed to enable a high-quality, trouble-free transfer of audio data from a computer to a professional sound reinforcement system. Despite offering a variety of functions and possibilities, many standard sound cards and interfaces often lack either balanced XLR outputs or a galvanically isolated USB connection. This frequently leads to interference, hum, poor transfer quality and insufficient output levels. With the A-1 live however, such problems become a thing of the past.

Easy handling
Using the A-1 live, the computer can be directly connected to the system via balanced XLR connectors, without the need for additional devices such as a mixer. A trouble-free connection is guaranteed, with no reduction in signal level and the galvanic isolation providing additional protection for your computer.

The A-1 live is a high-quality, two-channel USB audio interface with balanced XLR outputs and a galvanically isolated USB connection.
