Tri-Mode Speaker Wiring
Tri-Mode Operation is a unique feature which allows a two channel amplifier to drive a sub-woofer operated
in MONO mode, while simultaneously driving full range speakers in STEREO.
To engage the amplifier in this mode, place the Crossover (Subwoofer)
switch in the "FULL" position. Use a 100v non-polar 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 capactior component values to determine the desired
crossover frequencies.
