■ 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.
■ Phone Plug Wiring
Phone plugs for connection to the phone
jack inputs should be wired as shown to
the right. Be sure to use proper speaker
cable – NOT shielded instrument or line
cable – for all speaker connections.
