In Digital USB Mode
The USB DI Plus VC has an inbuilt 24 bit High Resolution digital to analog converter (DAC) which removes the need to use a Computer's existing internal sound card outputs, with their inherent noise and distortion.
The USB DI Plus VC installs as a fully compatible generic "Plug and Play" USB audio device, requiring no special driver program installation.
The USB DI Plus VC 's DAC delivers Professional Line Level audio signals to Left and Right balanced XLR outputs.
When switched to USB mode the USB DI Plus VC is powered via the USB cable, so no batteries or phantom power required to use it.
In Analog Mode:
Many Tablet Devices, Phones and iPads have no direct USB Digital Audio output, and interfacing their Audio with the professional world of balanced audio can be problematic.
Switching the USB DI Plus VC to Analog mode effortlessly solves this problem by buffering the audio signal from the Headphone or Line output and producing a Professional Balanced Line Level audio signal on Left and Right balanced XLR outputs.
To ensure reliability, Analog mode is passive with no batteries or phantom power required for use.
Both the USB DI Plus VC Digital and Analog operating modes feature full transformer balanced output isolation. This eliminates earth loops / ground hum and helps remove extraneous interaction noise and distortion ensuringt noise free operation even in the harshest audio environments.
