A:AnswerI looked at pictures of a Denon s700 AVR and it has rca inputs that you can use. They are labeled cbl/sat and media player for some reason, but these are the inputs you can use assuming this is the model you mentioned.
A:AnswerYou'd just need a computer, connect the turntable via USB and use Audacity or some other recording software (I like Final Vinyl if it's still available) to record the vinyl. Once you record it and save the files, you can do whatever you want with them. I put them on my phone and burn CDs of them.
A:AnswerYour key word is Passive, those are not powered speakers, so they won't work. You'll need powered speakers with a stereo or USB input, or a full stereo amp/speakers etc.
A:AnswerIt's AT's lower priced Elliptical cartridge. Replacement needles are about 35-40.00. I have no complaints with it and that 40.00 isn't too bad for replacement after 200-300 hours of play.
A:AnswerCheck AT they do sell a 78 cartridge/shell. It is easy/peasy to change the shell, in fact there is a place on the base for an alternate shell/cartridge.
A:AnswerGrab the latest version of Audacity from their site and when you are done capturing your vinyl, save the entire project as a Lossless project. Then when you do your edit, export as FLAC instead of MP3. You have the option thru Audacity to select what type of file export your recordings will come out as.
A:Answer1) Yes the Pioneer DJM S9 has two channels, each with stereo Phono inputs. It can also input by USB but I'd use that for other things. 2) Not directly but as the DJM S9 is the actual controller doesn't appear absolutely necessary. For further Turntable automation your gonna need something else.
