Re: repeater noise problems

Right.  All units generate some noise (noise floor) that's just the nature 
of
reality...right now.  If the unit's functioning correctly, that noise floor
should be low enough compared to the signal on it so that you don't notice 
it.
(I don't on mine)  However, if you are pluging it into a guitar amp, it's 
going
to expect a tiny signal and hope to boost it a lot. (instrument level to 
line
level)  If it's already at line level, it's still going to boost the whole
thing, noise and all.  You'll have to turn down your signal or you may 
distort
the input.  Now the noise is a LOT closer to the signal level.  Not good.
Running distortion effectivly ads compression which is even worse.  I did 
an
experiment with my guitar amp.  First, I plugged the guitar right into the 
main
in.  Not much noise.  Then I put the repeater before the amp.  A lot of 
noise.
Then I put the repeater in the amps stereo line level effect loop.  Noise
gone.  That's why I bought this amp, because it was one of the only guitar 
amps
out there that had a stereo line level effect loop.  (a Johnson JT50) and 
it
was being blown out by Musician's Friend for $250.  I think it's a hell of 
an
amp for it's price.  But I digress...
