low level converter

zx3chris · 19th April 2003, 06:42 PM

im looking for a schematic for a low level converter---- you take the leads off of a speaker and it converts it to low level signal, for rca input to another amp.. i have a 2 channel amp that i use as my main amp and i want to use another 2 channel amp just for subs--but i dont want to have 2 volumes.. thx

Why don't you use a voltage divider with resistors?
It's easy:

use 2 resistors in series (220k and 22k)
connect one terminal of the 220k to the speaker(+) and one terminal of the 22k to the speaker (-)
join the other terminals of the resistors and connect to the input of the other amplifier.
ground is taken from speaker (-)

only applicable if the main amp is not bridged
