Ok, here's the problem:
   I've hooked up a (ceramic-cartridge) turntable to my boom-box's AUX input.
This works fine, execpt that records sound much 'tinnier' than they should.
I would guess this is due to the RIAA equalization curve that records are
cut with.  What I want is a simple filter to de-equalize the signal to match
a standard AUX-type input.  This should preferably be a simple R-C passive
filter, so that I don't have to build a separate power supply for it, but if
the signal loss would be too low, a simple single-transistor per channel
active filter would be OK.  Incidently, this circuit does not have to be
super-accurate; this is not rec.audio.high-end here!

Sorry if this is sort of a basic question, but I don't know how the RIAA
equalization curve is defined.  What is the RIAA curve anyway?


Anyway, thanks in advance for your help...
