To connect the home studio the MacBook's with the consoles it needed this cable. The signals are now fed high-quality analog-to-digital converter (ADC) to the MBP and music recordings for reproduction via digital-to-analog converter (DAC) fed back to the mixer's. Crystal clear sound! If not deceive me my ears, the sound quality is even better than with the pure analog transmission. The cables are surprisingly flexible, easy to handle and above all both connectors fit exactly side by side in the bushes of the Mac (and sit there also firmly). Practically - as mentioned in other reviews - the protective caps on both sides.
Through a combined transmission and mixer with USB and analog I was always right significant noise with purely analog cabling has quite annoyed and disturbed. The absolute highlight is now that this high-frequency Hintergrundpfeiffen is almost completely gone, only if one winds the fader really full, then you hear something.
