(C)TRI MODE
TRI MODE OPEATIONAL OUTPUT allows a Crossover(Subwoofer) to be operated in MONO
mode while the main speaker is playing in stereo.
Leave the Crossover(Subwoofer)Switch on FULL position.
Use a 100Volt,non-polar capacitor for a high pass crossover and a wire coil (inductor)to
block high frequencies from the Crossover (Subwoofer)as shown in the figure below.
Capacitor and inductor values as written in the below determine the crossover
frequencies.
The front and rear channels of this amplifier get this capability.
Only the rear left and right channels are shown below.
