Dual 32 bit DSP Th e SR9600 is on e o f the first products in the wo rld to use the n ew Cirrus Logic CS4950 2 DSP.

HDAM-SA2 Th e o rigin al HDA M® mo dule (High Defin ition Amp lifier Modu le) was de velope d in the mi d nineties to replace the IC op-a mps that were used to bu ffer the voltage portions of output s tages .

In this latest versio n, designe d for hi gh band width au dio sou rces, the signal path s are as short as possible, for reduction of external noise an d reduce d m ountin g area. Th e SR9600 uses 16 of these devices at th e jun cture b etween the p reamp lifier and power amplifier stages. 2

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 - 1394 is used to deliv er en cryp ted multi-ch annel audio fro m so urce p roducts like DVD-A an d SA CD to the receiv er. Th e advan tage i s 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 made fo r m ulti-ch annel an alo g. An other advan tage is that s ince the information enters the recei ver in digital fo rmat, it can 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). Flow Rate Control Th is circuit allo ws the recei ver to control the signal trans fer s peed. It us es the rece ivers extrem ely h igh precis ion clo ck to regen erate th e origin al digital sign al, elimin atin g an y jitter that migh t occur. Th is results in a fourfold decrease in distortion in t he au dible frequencies! 32 Bit DSD – PCM Co nversion Thi s Maran tz de signe d au dio c ircui t al low bit stre am from SACD t o high bit rate PCM f or post processing.
