Abstract:
A method for dynamically maintaining audio output balance in a stereo audio system, wherein said stereo audio system includes a base unit and at least four speakers, said method comprising the steps of:coupling a first control unit between a first of said at least four speakers and said base unit;coupling a second control unit between a second of said at least four speakers and said base unit;coupling a third control unit between a third of said at least four speakers and said base unit;coupling a fourth control unit between a fourth of said at least four speakers and said base unit, wherein each of said control units is positioned in close proximity to each of said respective speakers;indicating a physical position of a listener with respect to all of said control units via a remote control;determining a relative distance of said remote control with respect to each of said control units; andadjusting audio output of each of said plurality of speakers by adjusting a value of a variable resistor within each of said control units, wherein said value of said variable resistor within each of said control units, R.sub.s, is adjusted as follows:for said first control unit, ##EQU5## for said second control unit, ##EQU6## for said third control unit, ##EQU7## for said fourth control unit, ##EQU8## where t.sub.1 is a cumulative flight time between said first control unit and said remote control, t.sub.2 is a cumulative flight time between said second control unit and said remote control, t.sub.3 is a cumulative flight time between said third control unit and said remote control, and t.sub.4 is a cumulative flight time between said fourth control unit and said remote control, so that true stereo balance audio is obtained at said physical position.
