I have a Stereo Audio feed for 2 Watts {at} 8 Ohms (per channel) that I need to
convert to "Line" level (I'm assuming this is around 1 Vac
Peak-to-Peak at a
much higher impedance) in order to pass the signal through an Equalizer, then
back thru a secondary Amplifier (probably 5-10 Watts per channel, not built
yet). Can this be done with a simple Voltage Divider like dual Pots and would
the pot(s) need to be Audio-taper?

Are there any industry standard Audio Amp ICs that deliver approx. 10W/RMS per
channel I should use for the last stage? I have a couple of National Stereo
Amps (Lm4755) rated at 11W/channel with low noise/distortion specs, I think.

I dismantled a very expensive TV to develop the Line-level outputs but could
only work out speaker taps (no schematic :( they go for over $50) and cannot
risk/afford to cause any damage by playing around . My old TV had
Audio/Line-out taps that sounded incredible through the Equalizer. :)
