TRI MODE OPERATIONAL OUTPUT allows a Crossover (Subwoofer) to be operated in MONO
mode while the main speakers are playing in Stereo. Leave the Crossover (Subwoofer) switch on
"Full" position. Use a 100 Volt, non-polar capacitor tor 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 have this capability. Only the rear left and right channels
are shown below.
