ABSTRACT:
In an adjustable power fader device for a loudspeaker system with at least four speakers right and left channel input signals are received by respective power fader circuits. Each power fader circuit has a variable resistor connected across its input terminals and a series of at least two speakers across its output terminals. The sliding terminal of the variable resistor is connected via a capacitor to the mid point of the series of speakers, one of which has good low pitch sound reproduction. The two sliding terminals of the respective power fader circuits are movable together and the level of audio signals applied to the loudspeakers is accordingly adjusted.
