IEEE-139 4
IEEE- 139 4 (o therwise kn own as F ireWire-„¢ o r i.Lin k-„¢) is a high sp eed (up to 400 mb ps) serial data bus th at is design ed to mo ve
digital informati on. It ha s se veral flavors, de pendi ng on whi ch type of data i s be ing u sed. For exam ple, in the video worl d, 1 394 is
used to m ove high de finition tr ans port stre ams , which are the MP EG-2 compre ssed bit stre am s that you could watc h, decoded on
your HD mo nitor at home. It is al so a stan dard conn ectio n for digital camco rders. In the audio wo rld wh ere th e SR9600 lives, IE EE -

both in fidelity as well as co nvenien ce, b ecaus e o nly o ne wire can be conne cted instead of the mu ltiple conne ctions tha t hav e to be

proc esse d for bas s ma nage me nt a nd ti me alignme nt like ev ery othe r si gnal . Thi s enables the ow ner to ha ve setup done once and e very
sign al will b e processed in a similar fash ion. To furth er add to the fidelity, flo w rate co ntrol is used alo ng with a sp ecial e xtremely high
bit rate conversion f rom DS D (f or SACD sou rces).
