damnspynovels Posted November 27, 2013 Report Share Posted November 27, 2013 Actually I'm not quite sure how to describe my question... I've just got a Jb940 - and I've read somewhere in the instructions about improving sound quality by adjusting the bit rate? I'm not referring to LP etc, but something to do with changing the bits between 16, 20, and 24? My set up would include a CD player that I think has a 24bit BurrBrown DAC in it, and a MacBook which I'll transfer audio (likely of 16bit origin) optically - but otherwise I'll be using analogue inputs. So what / how does this bit selection factor in the process? Quote Link to comment Share on other sites More sharing options...
trott3r Posted November 27, 2013 Report Share Posted November 27, 2013 As i understand it keeping the same bit depth as your source maintains quality. ie CD is 16bit so have the MD set to 16bit when you record from it. From vinyl 24bit on the analogue inputs. Quote Link to comment Share on other sites More sharing options...

MDietrich Posted November 27, 2013 Report Share Posted November 27, 2013 Yeah that would make sense, but I think I also read something about how it only affects digital output? That´s correct. The 24 bit setting affects the digital output only, the input (digital or analogue) is always 24 bits. It´s for transferring WideBitStream recordings with full quality. Switching to 16 bit will dither the 24 bit files to 16 bits without truncating values. In case you are using your JB940 with an external DAC (or an amp with digital inputs) I´d set it to 24 bit. It doesn´t matter how it was recorded as MD always encodes with 24 bit precision. Quote Link to comment Share on other sites More sharing options...

Exception: a DAC or a recorder (DAT for example) that´s not 24 bit capable. For those it´s 16 bit. Quote Link to comment Share on other sites More sharing options...
