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.
Connect the NEGATIVE SPEAKER TERMINAL to the
RIGHT CHANNEL NEGATIVE AMPLIFIER TERMINAL.
Connect the POSITIVE SPEAKER TERMINAL to the
LEFT CHANNEL POSITIVE AMPLIFIER TERMINAL.
Connect the NEGATIVE SPEAKER TERMINAL to the
RIGHT CHANNEL NEGATIVE AMPLIFIER TERMINAL.
Connect the POSITIVE SPEAKER TERMINAL to the
LEFT CHANNEL POSITIVE AMPLIFIER TERMINAL.
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 subwofer, as shown in the figure below. Pls review the table below
for inductor and capacitor component value, to determine the desired
crossover frequencies
