(C)TRIMODE
TRIMODE OPEATIONAL OUTPUT allows a Crossover(Subwoofer) to be operated in MONO
modewhile the main speaker is playing in stereo.
Leavethe Crossover(Subwoofer)Switch on FULL position.
Usea 100Volt,non-polar capacitor for a high pass crossover and a wire coil (inductor)to
blockhigh frequencies from the Crossover (Subwoofer)as shown in the figure below.
Capacitorand inductor values as written in the below determine the crossover
frequencies.
Thefront and rear channels of this amplifier get this capability.
Onlythe rear left and right channels are shown below.
