For analogue inputs it uses quality VS Preamps, its power unit has low noise level, body is made of aluminum and it supports Direct-Box ( DI ) function for electro-magnetic interference protection on live concerts. Card supports Roland VS Streaming technology and ASIO 2.0 and WDM ( in Windows XP, Vista, 7, 8 and newer ) and Core Audio ( in Mac OS X ) interfaces for tight integration with modern DAWs : Cackewalk Sonar, REAPER, Avid Pro Tools, Ableton Live, Steinberg Cubase, FL Studio and others.
