Technical specifications
Depending on your playback application, this selection can also be
made from within the audio software itself. Your on-board soundcard
will remain as the default device, so that any system sound for
example won't be transmitted via the A-1 live.
The A-1 live is a high-quality, two-channel USB audio interface with
balanced XLR outputs and a galvanically isolated USB connection.
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. 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.
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.
The A-1 live is compatible with Windows XP, Windows Vista and
Windows 7 (32-bit and 64-bit), as well as Mac OS 10.4 – 10.7 and
Linux from Kernel 2.6.
