Dual Tri-Mode Speaker Wiring

Tri-Mode Operational Output is a unique feature which allows a Crossover (Subwoofer) to Be operated in MONO mode, while the main speakers are playing in STEREO.

To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the "OUT" position. Use a 100v non-polar capacitor for a high pass crossover and a wire coil inductor to block high frequencies from the Crossover (Subwoofer) as shown in the figure below.Please review the table below for inductor and capacitor component values to determine the desired crossover frequencies.
