ENGLISH ■ 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.
