The Bush MTT1 does have a
built-in preamp so you can connect it straight to the line-in on your soundcard.
You will of course need to find the correct cables to do this, or adaptors at least. Does the Bush have phono sockets on the back or phono leads straight out? Either way you will need a
phono to 3.5mm stereo jack plug to attach it to your sound card.
Record Now DX is a Japanese product from
Sonic and looks more like a CD burner than audio recording software. As I'm not familiar with the product I would suggest trying
All Sound Recorder XP.
