AUTOMATIC AND SIMULTANEOUS CONTROL OF LOUDNESS AND LOUDNESS COMPENSATION OF AN AUDIO SIGNAL

摘要

The invention disclosed is a room volume control that simultaneously and automatically controls both the loudness and the loudness compensation of sound from speakers of an audio system as the volume level is changed. A resistive volume control having a movable contact provides a different resistor value from an input terminal of the volume control to the movable contact for controlling the loudness of an audio signal. A parallel circuit of an inductor and a capacitor coupled through the movable contact is in series with the resistor value of the resistive volume control from the input terminal to the movable contact for controllin g the loudness compensation of the audio signal.
