• Plug and Play: The USB DI-Q installs as a fully compatible 'Plug and Play' generic USB audio device so does not require any special driver installation on Mac OSX, Win7/8/10.
• Compatible: The USB DI-Q is ideal for interfacing any USB equipped computer with the balanced inputs of a professional sound system.
• Retrofit: The simplicity of the setup of the USB DI-Q means that this product can be integrated easily into the existing AV infrastructure of a building. 
• Simple: Once in place, the USB DI-Q only requires touch button operation so that it can be used by non technical operators.  
• The USB DI-Q is housed in a heavy duty all-steel chassis finished in attractive matt textured powdercoat, with hardwearing epoxy screen printing and non-slip rubber base pad. It is ideal for interfacing any USB equipped computer (especially notebook/laptop computers) with the balanced inputs of professional sound systems.
