Digitizing Vinyl. Help!
Time has come to digitize my Vinyl collection. Having successfully
copied tape material to CD, I thought this would be easy! My equipment is a Denon DP-35F Turntable with a Denon DL-300 Cartridge, a New ART "USB Phono Plus" interface and a Dell Latitude D810 Notebook equipped with RIP Vinyl. This past weekend I copied three albums. The signal is clean but not strong. I have the gain on the USB Phono turned to the max. But, the meter in RIP barely rises about the quarter way mark. If I look at the signal in Audacity it is pretty "thin". I could comfortably use at least 3dB more. Do you have any thoughts on what is "wrong"? And, what can I do about it? You guys have given me great advice in the past. Many thanks Adrian |

If I had to guess, without doing too much research for you, I'd wager that the USB PHono Plus was designed with MMC's in mind, and not the small output MCC that you have. -- /"\ ASCII Ribbon Campaign | Todd H \ / | http://www.toddh.net/ X Promoting good netiquette | / \ http://www.toddh.net/netiquette/ | http://myspace.com/bmiawmb |

Does anyone have a recomentation for a more appropriate cartridge. Thanks Adrian |

Your MC cartridge has a very low output compared the the more usual MM (Moving Magnet) cartridges - I doubt a USB phono interface would sport this. geoff. |

Whether MC cartriges have any inherent benefits over MM cartridges has always been controversial. One of the finest MM cartridges ever made still costs less than $100. It's hard to get a good MM preamp for $100, and MC preamps are generally far more expensive. |

It will have an input stage better suited to your low-output cartridge. Use that as a preamp, feeding Tape Out into Line In on the ART, switching out the RIAA stage. |

Adrian You don't have to 'set it up' per se...just plug it in, in the vicinity of the turntable and computer...ie you don't need speakers, antenna or anything else. Put it under your monitor.... Space might be an issue, but you're just setting it up as a preamp for your computer...one cord for power, one double RCA to the preamp, and start ripping while you're figuring out your cartridge issues. jak |

The background noise on the vinyl will dither the quantisation quite effectively. Whilst ideally one would record with the peak signal just failing to hit 0dBFS, in practice even with a 16 bit ADC when digitising vinyl anything up to around 12dB of gain could be retrospectively applied to the digital signal without audible quantisation noise becoming apparent.

Whilst ideally one would record with the peak signal just failing to hit 0dBFS, Not necessarily ideal, due to the possibility of intersample peaks. It's advisable to record with peak samples a dB or three shy of 0 dBFS, unless you have accurate peak monitors that show you what the *output* level is. ___ -S "As human beings, we understand the world through simile, analogy, metaphor, narrative and, sometimes, claymation." - B.

If he is recording at a lower than optimum level then it is well worth using the extra bits, to reduce the detrimental effect of bringing up the level once digitised. It is a long time since amounts of data like that have been significant. And once on CD he can delete the computer data anyway. Sheesh. geoff |

If he is recording at a lower than optimum level then it is well worth using the extra bits, to reduce the detrimental effect of bringing up the level once digitised. It's very unlikely that there will be any audible difference using 24-bit unless the level is increased significantly (20dB or more) because the background noise from the vinyl will dither the quantisation. What matters far more is to use a high-quality RIAA amp and a low-distortion ADC. It is a long time since amounts of data like that have been significant. And once on CD he can delete the computer data anyway. Sheesh. But many audio recording programs only work in 16 bit. There is no advantage to using 24-bit for this purpose so it's not worth the extra hassle. David. |

A MC preamp or transformer raises the signal above the noise floor of the MM preamp. Since there is currently no MC preamp or transformer, the noise floor of the MM preamp is probably the weakest link. Before saving it to any 'lossy' compression method, simply amplify it in Audacity. This is a mathematical operation, and the 'clean signal' will be end up being as loud as you want it to be. Problem here is that there's always an analog domain noise floor, if only in the existing analog-to-digital converter. In this case I expect that the MM RIAA preamp is the weakest link. I base this on many experiences with them. Even with 16 bit converters, a MM RIAA preamp is the weakest link. Let me give a real world numerical example. If I adjust a good MM RIAA preamp so that the preamp clips at a slightly higher level than a high-trackability cartridge mistracks on a test record, the needle-up noise floor will be 70+/- dB down. Since the noise floor of a good 16 bit converter is more like 96 dB down, the weakest link is the MM RIAA preamp. However as you amplify it, yo will also bring up the quantisation noise. It is best to optimise your recording level first. Agreed. And that's why there are such things as MC pre-preamps and transformers. The effect can be reduced by ensuring you are recording at 24 bits resolution. A 24 bit converter does no more good - it just gives a higher resolution rendition of the noise in the MM RIAA preamp. |
