HOW TO BEGIN RESTORING OLD RECORDS.

CONNECTING


a)
The record player should be placed the furthest away from the computer and from the screen. (Risk of induction hum)

b)
If you have a simple turn table with a piézo-electric head, just connect to the "LINE IN" of your sound card.

c)
If you have a "integrated" record player, connect to " LINE IN " of your sound card. If the record player has no 'OUT' sockets, it will be necessary you to tinker a bit to fit them in.
And if you do not know how to do this, find somebody who does. (The solution to connect the outlet of loudspeakers to the " LINE IN " of your sound card can be fatal to the quality of the the sound and DANGEROUS for your equipment)

d)
If you have a setup consisting of a turn table (incorporated or not) and an preamplifier and amplier, connect the "Auxiliary" outlets of your setup to the " LINE IN " of your sound card.

e)
If you have a record player which head is not a piezo-electric and you don't have a preamplifier, it will be necessary for you to get one.
It should not cost more than some 85 Euros. One can still find these at electronic stores specialized in sound systems. One can also find electronic "kits" that you can build. (If you know how to handle a soldering iron)
This preamplifier must necessarily be of a R.I.A.A. type.

f)
The lead depends on the mechanical configuration of the connectors equiping the preamplifier and those equipping your sound card. You can find all sorts in computer shops.

Jack


"Jack" connector.
In general plugged into the
"Line In" of the sound card.
R.C.A.


"R.C.A." connectors.
In general plugged into the
preamplifier's output.


g)
You MUST NOT connect your analogical source to the " MIC " ( microphone) of your sound card. Otherwise you will end up having a disastrous digital saturation

h)
Finally the sound card is an essential element acting on the quality of the final result.
Very numerous cards of big brands offer a quality of conversion digital to analogical that is more than satisfactory, but these even cards skimp seriously on the quality of the conversion analogical to digital.
Few people of the general public use this function, thus it is evaded for economic reasons.
On the NET one can find numerous references to these problems and also help for choosing card if you decide to improve the quality of your recordings. (But to begin, maybe this is not necessary.)
