What's the frequency response of vinyl?

Dear Gnugear: If we take in count what is already done on Lp recording we can say that the frequency range could be this: 8Hz to 50kHz, the 1812 recording on Telarc goes to 8Hz and the cutting machine on the recording goes to 50kHz: so this is the theorethical frequency range.

Now, which is the frequency range response that we normally heard at home systems?, the answer is a complex one because there are several factors that define that frequency response range: the recording it self, the cartridge, the phonolinepreamp, amplifier, speakers and room interaction.

The whole frequency range response never was/is a problem with the analog reproduction recordings: we have all the " music " frequency range like in a live event.

Regards and enjoy the music.

google RIAA frequncy curves, etc. mono stereo....its limited by our ears

Here I am again quoting Poaul Ladegaard.Anyway the 8hz resonance is due to the rubbish that exists in the vinyl groove at about the 3-4hz level,so there is your real limitation to the bass end.The Sheffield discs indeed did go out to 50Khz and Stereophile's John Atkinson found that most commercial vinyl seems to extend typically out to about 35Khz most days.

Stan Ricker reported that his cutting system could cut signals well above 100 kHz on his master lacquers. Can this be transferred to vinyl pressings? I dunno. Only a few cartridges spec'd out that far (top line Allaerts, Technics EPC).

If any of you guys were alive in the 1970s :) remember the CD-4 system that RCA used for 4 channel? The LPs were cut as 2 channel records, but had the rear channels imposed on a 42KHz FM carrier that was *also* cut on the record. And this was with 1970s cartridges! (of course there were CD-4 cartridges that they recommended, but a good 2 channel unit would work too).

IOW, exceeding CD bandwidth is a piece of cake. You can do that with cassettes for pete's sake!
