PURPOSE: To improve the efficiency of a crossover network by forming a tap in a autotransformer and coupling outputs from taps to a tweeter and a woofer. CONSTITUTION: The output signal of a sound output amplifier 1 is connected to respective one terminals of at least two autotransformers 3a and 3b and the other terminals are grounded; and the taps a1 to a6 are formed halfway on respective single windings and the output signals from the taps a1 to a6 are coupled with the tweeter 2a and woofer 2b. |
