Abstract
An apparatus and method for providing a centralized speaker system that allows multiple speakers connected to a central amplifier speaker line to be monitored and controlled from a central location via a master/slave protocol. The centralized speaker system comprises a central station for selectively communicating at least one of a command and an information signal to a destination device. A tone generator is adapted to communicate an activation tone to the destination device. An amplifier, which is colocated with the central station, is adapted to amplify the signals to the destination device.

A speaker control system, comprising:
- a central station for selectively communicating at least one of a command and an information signal to a destination device, wherein said destination device is associated with a speaker;
- a tone generator for generating an activation tone for supplying power to said destination device;
- and
- an amplifier colocated with said central station for amplifying said information signal and said activation tone, prior to being received by said destination device.
A method for providing centralized speaker control, comprising:
- selectively communicating providing at least one of a command signal and an information signal from a central station to a destination device, wherein said destination device is associated with a speaker;
- generating an activation tone using a tone generator for supplying power to said destination device;
- and
- amplifying said information signal and said activation tone, prior to being received by said destination device, using an amplifier colocated with said central station.
