TRI MODE operation output allows a subwoofer to be operated in mono mode while the main speakers are playing in stereo. Leave the crossover
switch on “Full” position.
Use 100 volt, non-polar capacitors for a high pass crossover to filter out low frequencies and Air- core or
Ferrit- ore coils with a minimum diameter of 1 mm / 0.039” for the lowpass crossover to filter out high frequencies.
The capacitor and inductor values as written in the above table. The front and rear channels of this amplifier get this capability. Only the rear left and
right channels are shown on the above pictures.
