STANDARD OR BI-WIRE (BI-AMP) INPUT SELECTION:
The input to the crossover networks can be set up two ways:
Standard: Your crossovers are pre-set in this position at the factory.This position is selected by placing the
jumpers in the lower position as shown above. Use this setting to drive the crossovers with a single amplifier
channel or pair of wires. In this mode, you will only use the input connections marked “Main Input” on the
crossover cover (“INL+” and “INL–” on the crossover circuit board.) Follow the white markings labeled
“Standard” on the crossover cover.
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.
