Daisy chaining of tournament audio controllers

1. A system for processing audio signals, the system comprising:

a headset operatively coupled to a first audio controller, said first audio controller being in a daisy chain of audio controllers, said system being operable to:

receive a chat signal from a user of a second audio controller in said daisy chain of audio controllers;

receive a microphone signal in said headset;

sum said chat signal with said microphone signal;

communicate a chat signal from a user of a third audio controller to said user of said second audio controller in said daisy chain if said first audio controller is not at an end of said daisy chain of audio controllers;

communicate said summed chat signal and microphone signal to said user of said second audio controller if said first audio controller is at an end of said daisy chain; and

communicate said chat signal to an output of said headset.

2. The system of claim 1 , wherein the first audio controller is operable to remove said microphone signal from said summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with said microphone signal.

3. The system of claim 2 , wherein the first audio controller is operable to sum said chat signal with said microphone signal at an amplitude set by a user of said headset after said removal of said microphone signal from said summed chat signal and microphone signal.

4. The system of claim 3 , wherein the first audio controller is operable to communicate said summed chat signal and microphone signal at an amplitude set by said user to said headset.

5. The system of claim 1 , wherein a chat loop switch is coupled to two summers, each of which is coupled to a separate terminal of a microphone.

6. The system of claim 1 , wherein the first audio controller is operable to sum a signal from a gaming console with said summed chat signal and microphone signal.

7. The system of claim 1 , wherein each audio controller in said daisy chain of audio controllers is coupled to a headset.

8. The system of claim 7 , wherein said chat signal comprises audio from users of said headsets coupled to each of said audio controllers in said daisy chain.

9. The system of claim 1 , wherein said microphone signal is a balanced signal.

10. The system of claim 1 , wherein the first audio controller is operable to convert said received chat signal from a differential signal to a single-ended signal while being summed with said microphone signal.

11. A method for processing audio signals, the method comprising:

in a headset coupled to a first tournament audio controller (audio controller), said first audio controller being in a daisy chain of audio controllers:

receiving a chat signal from a user of a second audio controller in said daisy chain of audio controllers;

receiving a microphone signal in said headset;

summing said chat signal with said microphone signal;

communicating a chat signal from a user of a third audio controller to said user of said second audio controller in said daisy chain if said first audio controller is not at an end of said daisy chain of audio controllers;

communicating said summed chat signal and microphone signal to said user of said second audio controller if said first audio controller is at an end of said daisy chain; and

communicating said chat signal to an output of said headset.

12. The method of claim 11 , comprising removing said microphone signal from said summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with said microphone signal.

13. The method of claim 12 , comprising summing said chat signal with said microphone signal at an amplitude set by a user of said headset after said removal of said microphone signal from said summed chat signal and microphone signal.

14. The method of claim 13 , comprising communicating said summed chat signal and microphone signal at an amplitude set by said user to said headset.

15. The method of claim 11 , wherein a chat loop switch is coupled to two summers, each of which is coupled to a separate terminal of a microphone.

16. The method of claim 11 , comprising summing a signal from a gaming console with said summed chat signal and microphone signal.

17. The method of claim 11 , wherein each audio controller in said daisy chain of audio controllers is coupled to a headset.

18. The method of claim 17 , wherein said chat signal comprises audio from users of said headsets coupled to each of said audio controllers in said daisy chain.

19. The method of claim 11 , comprising converting said received chat signal from a differential signal to a single-ended signal while being summed with said microphone signal.

20. A system for processing audio signals, the system comprising:

a headset coupled to a first tournament audio controller, said first audio controller being in a daisy chain of audio controllers, said system being operable to:

receive a chat signal from a user of a second audio controller in said daisy chain of audio controllers;

receive a microphone signal in said headset;

sum said chat signal with said microphone signal;

communicate a chat signal from a user of a third audio controller to a user of said second audio controller in said daisy chain if said first audio controller is not at an end of said daisy chain of audio controllers;

communicate said summed chat signal and microphone signal to said user of said second audio controller if said first audio controller is at an end of said daisy chain;

sum said chat signal with a signal from a gaming console and a second microphone signal 180 degrees out of phase with said microphone signal; and

communicate said summed chat signal and signal from said gaming console to an output of said headset.
