Description
Settings
To select the A-2 live as your default audio device under Windows,
go to the Control Panel -> Hardware and Sound -> Audio Devices.
Here you can select the A-2
live as your default device.
The A-2 live will appear in
the operating system as USB
Audio DAC.
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-2 live.
The A-2 live is a high-quality, 2-channel USB audio interface with
galvanically isolated AES/EBU digital audio output.
Digital audio signals can be directly transferred from a computer to
a professional sound reinforcement system, such as Airea, without
any reduction in sound quality or level.
Despite offering a range of features, many standard sound cards
lack an AES/EBU output. This frequently results in interference,
hum, poor transfer quality or insufficient output level. With the A-2
live, these issues become a thing of the past.
Connect the A-2 live to a free USB port on the computer and it
will be ready for immediate use. No additional driver installation is
necessary.
The A-2 live is compatible with Windows XP, Windows Vista,
Windows 7, Windows 8 and Windows 8.1 (32-bit and 64-bit), as well
as with Mac OS 10.4-10.8 and Linux from Kernel 2.6.
