Re: [ARSCLIST] Good industrial-strength LP cartridge for spoken-word material/stanton
kind of in reverse order but you will see why..
1) All magnetic cartridges used today require additional amplification to be used with a turntable connected to the "line in" of a computer sound card. Thus the term pre amp(lifier).
Many Hi Fi stand alone units have these built internally, with jacks labeled "Phono in" as well as "line in".
Computer sound cards are specified as "line in" devices or microphone.
2) RIAA eq? This is a specific recording standard used in the recording and reproduction of LP recordings.
To compensate for mechanical and acoustical limitations of disc recording the high frequencies are boosted by a specific amount and the low frequencies are reduced by a specific amount.
The Recording Industry Association of America (RIAA) adopted an industry standard for all records. This is known as the RIAA curve and modern "Pre amps", as described in item 1, have this equalization network included in them.
At one time several companies (Shure, GE, CalRad) had pre amps with a switch to provide mic, flat (no eq) or phono with eq.
#3) 47k,220/200 ppf capacitor network. This is a specific resistor/capacitor combination that cartridge manufactures use to assure a response from their cartridge without sever peaks in response.
Some pre amps have adopted this others leave it to the user to match the particular cartridge they are using.
The components are standard off the shelf components from RShack, local electronics store or ham radio outlet.
I hope this hasent made things more confusing... ive tried to demystify the engineer language and get it to street level.
