837850	2009-12-09 09:07:00	You'd be better off just plugging the RCA into a 3.5mm line in jack.	roddy_boy (4115)
837851	2009-12-09 17:21:00	I wonder if you could plug an ordinary turntable with RCA leads into a computer with an RCA to USB adapter. :) Sure, why not. Is there enough voltage output to be acceptable for that? How about RCA-to-1/8" stereo into the sound card mic-in?	SurferJoe46 (51)
837852	2009-12-09 18:51:00	No chance of blowing something up. :)	Trev (427)
837853	2009-12-09 18:56:00	I wonder if you could plug an ordinary turntable with RCA leads into a computer with an RCA to USB adapter. :) No, of course not, except if it had a crystal pickup which give a high output. Possibly a ceramic cartridge would have enough output at around 100mV, but the characteristics still need to be matched with a passive equaliser which would reduce the signal. Magnetic cartridges give around 5 millivolts output, so a pre-amplifier is required. The USB turntables, and the DSE LAB 1100 have pre-amps built in. Also the pre-amps have RIAA equalisation networks, without that the playback would be awful.	Terry Porritt (14)
837854	2009-12-09 19:06:00	Yes forgot about the pre-amp side of things. :)	Trev (427)
837855	2009-12-09 19:34:00	The 'cheap' USB turntables usually have ceramic cartridges, and el cheapo pre-amps, from what I have read on 78rpm forums. These would be not as good as magnetic cartridges. I have also read that with some el cheapos the speeds can be a bit variable, giving a bit of 'wow'. The LAB 1100 turntable at DSE looks good value for money. Edit: but it is not USB, so it would just be plugged into your sound card. Forget ceramics. They were the cartridges that wrecked so many of my records back in the 60s and 70s until I could afford a decent magnetic cart..	paulw (1826)

In those days when you finally found some lightning stricken tree limbs and got the fire burning and threw all the saber toothed cats out of the cave, you'd relax and carve new needles for your Edison Cylinder.

I don't recall ever having any sort of cartridge when I had a turntable all those eons ago. In the early days you just replaced the stylus. It looked like a short needle - it was simple, made of metal, you could buy several at a time in a small tin. They got blunt and you replaced them. Subsequently capitalist man (ie Americans) learned how to make more money out of this simple process. They made them more complex and made them out of plastic and precious metals like semi precious stones that were shaped to fit in the grooves of the record. Some of them worked on magnetism. They came to be called cartridges - "needle" seemed inadequate to their makers. These votive offerings to the Gods of Capitalism became vastly expensive, and unnecessary to the auditory capacity of 99.9% of ordinary human beings. However, they were extremely necessary to the directors and shareholders of the companies that made them because they brought in much wealth. However, turntables were eventually surpassed by developments in technology such as tape decks. The Gods of Capitalism began to demand and consume ever more complex bits of technology called "heads". And so on and so on...	John H (8)
