I initially used this to connect my Linn LP12 turntable into my computer and transfer vinyl. Latterly, I used this with some recording machines and a PC. This was an expensive high end interface when new.
Usefully this is the USB version so can connect straight to a PC for recording. Please note you will need something else to monitor as this does not have a DAC buit in (I used a DAC initially with the hi-fi then just used the PC and CD recorder headphone sockets). Very useful as a mastering converter and usefully it can create a second copy at a different sample rate - I used the PC at 96KHz and could enable the secondary sample rate at 16 / 44.1 to connect to my CD recorder.
Please google to check further if needed. At the moment, I can't find the original box so it will be packed in a different box. Only the interface is included in the sale - nothing else (although can include a kettle power lead).
