CRITICAL INFORMATION! Weunderstand that the desireto listen to yourfavoritemusicthroughthis fine componentmaytake precedenceover reading this document.However,your SBP-64X is a verysophisticatedmulti-computer systemas wellas a state of the art audiophilecomponent.It should alwaysbe connectedwith great care. Forthis reason,wehavecompiled this installationguideto enableyouto "boot" yourprocessor quicklyandcorrectly,withoutthe possibilityof damage throughhaste.
Caution:Theblue SpanningCablesare proprietary in both their material design, and their "pin out" connections. Donot modify, substitute, or extendthemin anyway!Thiswouldincura highrisk of damageto both the powersupply andprocessorwhichwill void all warranty coverage. 2. Runthe, maleend of the suppliedACcordfromthe powersupplylocationto a nearby~vall socket.Thiswill be easierto accomplish now,as the component itself is not in the way.
Note:Careshouldbe takenin selectingthe typeof cableusedto link the digital sourceto yourprocessor.If coaxialcable is to be used,it shouldbe non-capacitive andhavea bandwidth in excessof 1OMHZ to preventdropout errors. If available, westronglyrecommend fiber optics for their ability to completely isolate all groundingbetweencomponents,thereby preventing any player/processor groundloopinterferences. AnalogOutputs 1.
Q. A. Q. A. Q. A. Q. A. Q. A. Q. A. Q. A. Q. A. I ownboth a CDandDATplayer.Do I have to change mycables every time I listen to a different digital source? No. YourSBP-64X will accommodate both thefiber optic an~l coaxial input. Simplyconnectboth sourcesusing the separate inputs. Note;Whenthe SBP-64X senses twolive inputs simultaneously,it will default to thefi~er optic link. Therefore,whenyouwishto listen to the sourcelinked with coa£ialcable, youmustturn the other (optically linked) source off.
KRELLDIGITAL SBP-64X DESIGNFEATURES Software BasedProcessingrequiresa perfectblendof exacting,multifaceted technologies, fromhightech digital innovationto an ultimaterefinement of analog circuit design. Onthe nexttwopages,wewill brieflypointout ourmethods of addressing these requirements in the KrellDigitalSBP-64X. INPUT TheSBP-64X will accommodate bothCoaxialandFiberOpticalinput to insure compatibility withanydigital sourcewithdigital outputs.
our processorsgivinga true recreationof the original musicperformance, without the colorationsnormally associated withintegratedcircuits. BALANCEDOUTPUT TheSBP-64X provides balancedoutputs for those with the complimentary components whichallowthemto obtainstill lowernoiseanddistortion, whileproviding~orespecific imaging. CLASSiX" ANALOG DESIGN Theanalogsection of the SBP-64X is basedon classic Krell Highbias, Pure Class"A"design which hasalreadyset newstandards for excellence in musical integrity.
CLASS "A" In audio components, Class "A"represents an operatingstate for power supplies and circuitry whichis widelyacknowledged as havingsuperior sonic characteristicsto otherformsof operation.
