Cool

Hey Riccardo :-)

Neat idea. Speaking from experience your pre-amp will need to have an 'RIAA compensated frequency response' to play music off a cassette tape. To reduce rumble and hiss from the media the lower and higher frequencies are compressed and band-passed before recording, and then expanded by the compensator before playback. Using a flat response amp will give you a very mushy playback...

;-)

HELLO!, pre-amp like this? http://piperidis.smartdev.gr/MyWebPage/Contructions/Amplifiers/tapeplayer/tapeplayerEN.htm 

Yeah perfect, that should do it. Anything with a flatter response in the middle and slopes off the top and bottom edges will play it back better than a Mic pre-amp.
Thanks for the shout out.

I thought that cassettes are not encoded this way, vinyl records are in order to get the audio to fit the dynamic range of the medium. Like when I say make a cassette from one of my records, I take the preamp output from the phono preamp and run it into the cassette deck and just record the decoded audio to cassette like that. Everything plays back all nice too. Just curious.

That Dolby double-D symbol means it was squished with their response curve, most of it was. Vinyl has a steeper cutoff to remove the rumble from that, yes, which is RIAA, I got confused with the acronyms. However the principle is the same. The response curve from the tape head is dealt with by the preamp itself, the same as in a vinyl setup. So yes, it will sound fine coming out of the preamp. The filtering and compression / decompression was meant to be transparent to the user, thats all, it's a stage lower than phono jacks. 

Dont forget you cant record on vinyl so it only has a filter to remove noise, not a decoder to expand a coded signal ;-)

hey thanks for explaining what you meant!! As soon as you said Dolby I was like "so that's what he meant" hahahaha
