Power and Speaker Wiring
Tri-Mode
Tri-mode operation allows you to connect this amplifier to a pair of main speakers
plus a subwoofer on one pair of output channels. The main speakers will operate
in STEREO while the subwoofer simultaneously operates in MONO.
To set up the amplifier to run in this mode, put the crossover switches in the FULL
position. Insert high pass filter capacitors and a low pass filter inductor into the
wiring as shown below. Be sure to check the table at the bottom of this page to
determine the correct capacitor and inductor values for the crossover frequency
you wish to achieve.
