Patent
CA 2468201
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 controlling the loudness compensation of the audio signal.
