Dual Tri-Mode Speaker Wiring

 

 

 

AUDIO

 

 

 

 

 

 

Tri-Mode Operational Output is a unique feature which allows a subwoofer to be operated in MONO

 

mode, while the main speakers are playing STEREO simultaneously on one pair of amplifier output

 

channels.

 

 

 

 

 

 

To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the FULL position.

 

Use a 100V non-poplar capacitor for a high pass crossover and a wire coil inductor to block high

 

 

 

 

 

 

SYST

 

frequencies from the subwoofer, as shown in the figure below. Please review the table below for

 

inductor and capacitor component values to determine the desired crossover frequencies.
