1. A method for delivering amplified audio signals into a venue comprising the steps of:

  • at a first location;

    (a) generating an audio signal;

    (b) generating a first control signal;

    (c) generating a first RF signal;

    (d) encoding said first RF signal with said audio signal and said first control signal;

    (e) from a first transmitter, wirelessly transmitting in spread spectrum format said first RF signal encoded with said audio signal and said first control signal;

    (f) at a first receiver wirelessly receiving in spread spectrum format a second RF signal containing a second control signal but no audio signal;

    (g) detecting said second RF signal and separating therefrom said second control signal;

    (h) Identifying the separated second control signal;

    (i) evaluating the separated second control signal for controlling transmission of said first RF signal in accordance with values of the second control signal;

    at a second location spaced from said first location;

    (j) at a second receiver, wirelessly receiving the transmitted first RF signal in spread spectrum format containing said audio signal and said first control signal;

    (k) detecting said first RF signal and separating said audio signal and said first control signal therefrom;

    (l) identifying the separated first control signal;

    (m) evaluating the separated first control signal and controlling delivery of the separated audio signal in accordance with values of the first control signal;

    (n) rendering the separated audio signal audible if and only if said first control signal contains predetermined instructions to do so;

    (o) generating the second control signal;

    (p) generating the second RF signal;

    (q) encoding said second RF signal with said second control signal; and

    (r) from a second transmitter, wirelessly transmitting in spread spectrum format said second RF carrier signal containing said second control signal but no audio signal;

    thereby effecting one-way spread spectrum transmission of audio signals and two-way spread spectrum transmission of control signals between said first and second locations.
