Phono Box USB is an ideal phono preamplifier for both your hifi system and vinyl recording to PC or Mac. MM and MC cartridges will be welcome. The analogue output of Phono Box USB can easily be connected to a line-input (AUX,...) of your hifi and digitally via USB to your computer. Both outputs can be used simultaneously. Any professional recording software will give best results on Windows and Mac computer systems.  

This high-quality Digltal Audio Converter (DAC) delivers upgraded sound to any USB compatible computer. The USB DAC is ideal when used to bypass the low-grade internal sound card in your computer, adding a higher fidelity to your digital music library. Included with this DAC is an unique music player software package incorporating Direct Streaming Technology that outputs an exact bit-copy of the original source by resampling the Kernel Mixer of your PC. The software is compatible with Windows®, MacOS® and Linux® operating systems. Power is supplied to the USB Box via the USB port.
