Using A Channel Divider And Subwoofers; Phone Plug Wiring - Yamaha R112 Owner's Manual

■ Using a Channel Divider and Subwoofers

Using a channel divider in a multi-way system like the one shown in the diagram can
provide superior dynamic range and overall sound quality. The channel divider divides
the line-level audio from the preamplifier or mixing console into separate frequency
bands that are then sent to separate power amplifiers. The power amplifiers drive
speaker systems selected for optimum performance in the corresponding frequency
ranges.
