Tri-Mode Operational Output is a unique feature which allows a subwoofer to be operated in MONO
mode, while the main speakers are playing STEREO simultaneously on one pair of amplifier output
channels.
To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the FULL position.
Use a 100V non-poplar capacitor for a high pass crossover and a wire coil inductor to block high
frequencies from the subwoofer, as shown in the figure below. Please review the table below for
inductor and capacitor component values to determine the desired crossover frequencies.
