TRI MODE operation
Tri Mode Operation output allows a crossover (Subwoofer) to be operated in Mono
mode while the main speakers are playing in stereo.
Leave the crossover (Subwoofer) switch of FULL position.
Use a 100 Volt, 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.
