2. The sound control circuit according to claim 1 , wherein a first pin on the game port is grounded through a first switch to provide a temperature alarm function for the jukebox device.

3. The sound control circuit according to claim 2 , wherein a second pin on the game port is grounded through a second switch to increase volume.

4. The sound control circuit according to claim 3 , wherein a third pin on the game port is grounded through a third switch to reduce the volume.

5. The sound control circuit according to claim 4 , wherein a fourth pin on the game port is grounded through a fourth switch when a microphone is activated, to increase the microphone volume and reduce the volume of other audio sources that are managed by the jukebox device.

6. The sound control circuit according to claim 1 , wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a short period to obtain access to system configuration modification functions.

7. The sound control circuit according to claim 1 , wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a long period to cancel a musical selection being played, and other musical selections that are in a queue of songs to be played residing in a memory of the jukebox device.

8. The sound control circuit according to claim 1 , wherein the sound control circuit constitutes different hardware than does an input control circuit connected to the jukebox device.

9. The sound control circuit according to claim 8 , wherein both the sound control circuit and the input control circuit are configured (1) to access the configuration of the jukebox device, and (2) to manage the jukebox device, via respective peripherals connected to ports thereof.

10. The sound control circuit according to claim 1 , wherein the game port is further configured to manage any two or more of: sound signals provided by microphone input to the jukebox device, transmission of sound signals to loudspeakers from the jukebox device, and songs stored in a mass storage location of the jukebox device.

11. A digital jukebox device, comprising:

an operating system configured to manage operations of the jukebox device;

a sound control circuit configured to support a plurality of input sources for the jukebox device,

wherein the sound control circuit includes a game port, the game port comprising pin connectors operably connected to electrical switches of the jukebox device, the sound control circuit providing access to configurational and management-related settings of the jukebox device through the electrical switches, and wherein the sound control circuit is configured to power off the amplifier during initializing of the jukebox device and to power on the amplifier after the initializing.

12. The jukebox device according to claim 11 , wherein a first pin on the game port is grounded through a first switch to provide a temperature alarm function for the jukebox device.

13. The jukebox device according to claim 12 , wherein a second pin on the game port is grounded through a second switch to increase volume.

14. The jukebox device according to claim 13 , wherein a third pin on the game port is grounded through a third switch to reduce the volume.

15. The jukebox device according to claim 14 , wherein a fourth pin on the game port is grounded through a fourth switch when a microphone is activated, to increase the microphone volume and reduce the volume of other audio sources that are managed by the jukebox device.

16. The jukebox device according to claim 11 , wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a short period to obtain access to system configuration modification functions.

17. The jukebox device according to claim 11 , wherein first, second, third and fourth pins on the game port are grounded through a fifth switch for a long period to cancel a musical selection being played, and other musical selections that are in a queue of songs to be played residing in a memory of the jukebox device.

18. The jukebox device according to claim 11 , wherein the sound control circuit constitutes different hardware than does an input control circuit connected to the jukebox device.

19. The jukebox device according to claim 18 , wherein both the sound control circuit and the input control circuit are configured (1) to access the configuration of the jukebox device, and (2) to manage the jukebox device, via respective peripherals connected to ports thereof.

20. The jukebox device according to claim 11 , wherein the game port is further configured to manage any two or more of: sound signals provided by microphone input to the jukebox device, transmission of sound signals to loudspeakers from the jukebox device, and songs stored in a mass storage location of the jukebox device.
