Bi-Wire (Bi-Amp):
This position is selected by
placing the jumpers in the upper position as shown
below. In this mode, the input to the woofer’s low-
pass filter and the tweeter’s high-pass filter is
electrically isolated.This way, you can connect
different amplifier channels to the woofer and
tweeter sections (bi-amp), or you can run separate
wires for each section from the amplifier (bi-wire).
In this mode, you will use the Input connections
marked “Tweeter Input” and “Woofer Input” on the
crossover cover (“INL+”, “INL–”, “INH+” and “INH-
” on the crossover circuit board.) Follow the gold
markings labeled “Bi-Wire” on the crossover cover.)
Please note that the use of additional active filtering
on the amplifiers or outboard active crossovers is
not recommended in this mode for the woofer
low-pass or the tweeter high-pass.
