Sound Quality

[Zscoundrel]

That 'buzz' is probably a 60hz hum from the power lines.  Many of the 
better turntables used a very sensitive electro-magnetic pickup that put 
out a much lower line-level output than tape decks and stereo systems.  
You probably need to get a pre-amp or just hook the turntable into a 
stereo that is built to accept turntable level input and puts out 
standard line-level out put. 

Also, BE SURE that the green wire from the turntable is FIRMLY grounded 
to the frame of the pre-amp, stereo or computer.  The turn table must be 
a the same ground potential that all of the other components or you will 
get this annoying 60hz buzz. 

Note, the turn table MUST NOT be near the monitor or it will give you a 
nasty buzz as well.

The Supreme Court has ruled that they cannot have a nativity scene in Washington, D.C. This wasn't 
for any religious reasons. They couldn't find three wise men and a virgin.
