Tired of carrying bulky
devices all around to execute your acoustical measurements?
Duran Audio has developed a handy, compact, and yet highly accurate
USB microphone pre-amp to alleviate this problem. The AXYS® D-audio
USB Audio Reference Preamplifier is designed for use with acoustic
measurement software such as WinMLS, EASERA and Smaart for the
purpose of the precise capturing of audio data to ensure fast
and reliable STI figures without the common measurement setup
hassles. This extremely high quality unit can also be used for
the most demanding recording purposes.
D-audio provides two line
and two microphone level inputs and two transformer balanced
line outputs with software controllable local loopback functionality
and a rock steady 48V phantom power. The unit can be powered
by the USB port or an external power supply.
