Abstract

A channel divider that can suitably set a crossover frequency when a biwiring-connectable multiway speaker system including network circuits are used is provided. The channel divider includes a low-pass filter LPF and a high-pass filter HPF for dividing a band of a sound signal into a first output signal and a second output signal so as to output the signals, and a control circuit for controlling the filters. The channel divider has a sound output mode in which the control circuit sets a cutoff frequency fcL of LPF to a value higher than fc 0 by about ⅙ to 1 Oct., sets a cutoff frequency fcH of HPF to a value lower than fc 0 by about ⅙ to 1 Oct., and outputs the first output signal and the second output signal including frequency bands fcL to fcH when any crossover frequency fc 0 for defining the band division is specified.

First claim

What is claimed is:

1. A channel divider, comprising:
a digital signal processor DSP including a low-pass filter LPF and a high-pass filter HPF for dividing a band of an input sound signal into at least a first output signal whose frequency is lower and a second output signal whose frequency is higher than that of the first output signal and outputting them to a first output terminal and a second output terminal;
a control circuit for controlling the digital signal processor DSP…
