Digitizing Vinyl, Part Five: Preamps
The standard Party Line regarding audio is that analog is always better. It's "warmer and punchier" while digital is "cold and harsh." I'm not going to embark on a rant (8-track) about this (cassette), but I will sum up my experiences. The tube preamp I bought does two things. The first is it has much more low end response, probably between 4 and 8 dB if I had to guess. It also has a much smoother curve to the low end frequencies. The second thing I have noticed is a definite difference in the sound of the mid and high end. Sadly, I just don't know how to describe it. So I'll say this... I think the tube preamp sounds better. At the end of the day, I'm an obvious heretic who is methodically converting beloved records to digital, so I'm not a hater of the 1 and 0... But passing the signal through a tube on its way to being frozen forever on a hard drive seems to produce a pleasing result. That said, I have noticed it is easy to accidentally get slight distortion on bass drum hits and sub bass parts, so I have to be really careful with the volume knob. At which point it is probably worth offering another tip: test what you are doing. Specifically, record small sections, and play them back. It's better to use up 5 or 10 minutes double checking your settings than to record a whole side of a record and find out later you had some distortion.
While writing this, I just noticed that Bellari now makes a USB version of its tube preamp, which might be worth trying. I'll be writing about A to D converters in my next installment.

Digitizing Vinyl, Part Three: The Turntable
My first set up for digitizing records was a Techniques 1200 MKII turntable with a Stanton 680 EL Cartridge, plugged into a Vestax Mix Stick mixer, using an M-Audio Firewire A to D converter into my Mac Laptop running Peak LE to record. And it sounded OK. Sorta. The 1200 MKII has been a standard club turntable for decades. Its a direct drive workhorse with loads of torque and solid timing... but its not an audiophiles dream come true. The deal is, you want to keep noise out of the signal, and with a direct drive unit, the platter is essentially sitting right on top of the motor. If you use a belt driven unit, it makes it easier to isolate the motor from the platter, helping reduce vibration that might be picked up by the needle. Thats the theory anyway, the reality is that it isn't easy to hear that kind of noise during the loud parts of the music, but I wanted to get the cleanest grab that I could. Like I mentioned earlier, digitizing records is a pain, so I wanted to do it once, and get it over with. Frankly, the Vestax mixer was a bigger part of my equation, but I'll be addressing that in a later post.
Once I realized that I needed to upgrade, I started looking into USB turntables, this was in early 2007. At the time Ion was starting to get a name for is products, so I read some reviews. Several of them noted that the unit didn't have a grounding line, and there was a very slight hum. In the olden days, turntables had a ground line that was connected to the receiver to prevent an electrical hum. If the reviews were correct, it seemed like USB didn't quite fully ground the Ion units, but I wasn't sure. Being a gadgety guy I decided to jump into USB anyway. I bought a Stanton USB turntable at Guitar Center... And you know what? It hummed. A very soft 60 cycle hum. It went back to the shop the same day, and I swore off USB until they had real ground lines.
So with that option done, I decided to buy the cheapest new turntable I could that would still produce a clean signal. I found two contenders, the Rega P1 and the Sumiko Pro-ject Debut III. After reading reviews, I couldn't decided between the two, so I bought the first one I found in stock at a neighborhood Hi-Fi store. I'm a proud owner of a Rega P1. Generally I'm happy with it, although switching between LP and 45 means removing the platter and moving the belt from one pulley to another. Which is actually kind of cool. It comes with an Ortofon cartridge which sounds good, but it can't take too much weight. Some of the old Jamaican 45's I have been restoring need 3 or more grams of weight to get them to play through, but really that is my problem, not Rega's. I do still believe I'm picking up some rumble from the motor, but It's acceptable. It damn sure doesn't hum. So With the turntable issue solved, next came the preamp.

New Pressure Sounds Release: Pleasure Dub
Duke Reid died from cancer in 1974 and his nephew, Errol Brown, who had been a junior engineer at Treasure Isle and who would go on to become one of the key engineers at Bob Marley's Tuff Gong Studio, took over the studio controls. He mixed three dub albums at Treasure Isle that dressed down and dubbed up some of the best of the Bond Street catalogue. Snatches of the original vocals were woven in and out of mixes that sound as fresh and as vital today as they did when they were first released, both in their original sixties incarnations and their seventies counteractions. 'Treasure Dub Volume One' and 'Treasure Dub Volume Two' have been available in various incarnations ever since. However, 'Pleasure Dub', the best of the set featuring Errol Brown's cuts to rock steady classics such as 'The Right Track' by Phyllis Dillon, 'The Tide Is High' and 'Riding On A High & Windy Way' from The Paragons and 'Things You Say You Love' by The Jamaicans has never been re-pressed since its initial release. 'Pleasure Dub' is a record we have wanted to release for a long, long time and we are all delighted to be able to finally add a Treasure Isle album to the Pressure Sounds catalogue.Pressure Sounds, started in 1994, is up there with Blood and Fire and Soul Jazz, producing some of the best Reggae re-issues available. It is affiliated with Adrian Sherwood's On-U Sounds.

Digitizing Vinyl, Part Two: An Overview
There are literally hundreds of different ways to set up a system to digitize records, but most of them will have 4 main parts. Even if you have one of ION's all in one units, one way or another it will have the following things:
A Turntable -> A Preamp -> an Analog to Digital Converter -> A device to record on, probably a computer.
The turntable AKA "record player" can come in a variety of configurations, but most are either direct drive or belt driven. The preamp's job is to raise the volume of the turntable up to "line level" like your CD player or iPod. For decades, the job of preamplification was usually done by a stereo receiver, but new (cheap) receivers have omitted this option. The A to D converter takes the analog signal generated from your record, and converts it into digital glory. You can choose to do this with tons of different external boxes, or just roll with the built in audio input on your laptop. Finally, the recording device might be a computer, a minidisc player, a DAT deck, or a score of other devices that are on the market. As I mentioned above, some devices can combine one or all of these things. For example, if I had a spare 500 bucks, I'd pick up a Sumiko Debut III USB, which combines the turntable, preamp, and A to D converter. In the following posts, I'll be providing more detail about what I've tried, what worked, and what didn't.

Digitizing Vinyl, Part One: The Big Question...
Before you spend a single minute digitizing a record, make darn sure to ask yourself one question... "Why am I doing this?"
If your answer is along the lines of "I spent all this money on my records, and I don't want to buy this junk again for my iPod" then stop right there. If you are seriously longing to hear Eliminator by ZZ Top again, go buy the damn thing used on CD. Why look, Amazon has it for sale for under $3.50. Unless you just have an overwhelming need to keep busy, digitizing music from an analog source is a time consuming process at the best of times. Even if you buy a kit that comes with free software and a USB turntable, you still have to play through everything in realtime... Thats about 40 minutes per LP, not including clean up and splitting the audio file into named tracks with artist info. If you are dealing with an old record that is dusty and might skip, things can go downhill quick. Seriously, read a book or build a ship in a bottle. You should really try to only digitize records that aren't available for a reasonable price elsewhere. Believe me, I've done it and it just doesn't seem worth it at the end of the day.
Now what if your answer is "But records sound better." To that I can only suggest that you dim the lights, fire up the McIntosh amp, and enjoy your nice album. Digitizing a record because you like the way analog sounds, only to play it back on a digital device... well, if that floats your boat, more power to you. I personally can't recommend it for everyone.
Years ago I read that a shocking amount of records are not and will never be digitized and re-released. So If your grandmother left you more than 5 records in her will, the chances are good that you might have something that in the digital age, does not exist. Or if you're like me, that dusty old Well Charge 45 from Kingston might be the last survivor, and the quest for those gems makes all the trouble worth while. Further, some of the inexpensive audio restoration software can produce stunning, if not magical results, proving that math can actually be cool.
