Digital to analogue converter (DAC)
Converts the digital data signal into analogue signal that can be amplified and reproduced using speakers or headphones so that our ears can hear it.
In the case of video the data is converted into a video signal that can be reproduced by a display device so that we can see it.
Once data is converted to an analogue signal it then can degrade and lose its quality every step of the way. Most modern equipment is designed to keep data in the digital (Lossless) domain as long as possible.
In an ideal world data would be kept digital right up until the point that you see or hear it avoiding degradation.

The rear-panel USB Type-B allows you to use the A70 as a high quality off-board USB Soundcard/DAC. Because it is asynchronous (Allowing clock timing data to be synced to the PC) it allows for Jitter Free audio up to 192kHz/32-Bit from a PC, that with the right software is bit-for-bit accurate.
