PRESENTATION AUDIO SYSTEM
First Claim
1. A presentation audio system comprising:
- a. at least one IR microphone/controller wherein said IR microphone of said at least one IR microphone/controller is operable to transduce sound into audio signals and said IR controller of said at least one IR microphone/controller is operable to transduce manual control manipulations into commands, and wherein said audio signals and said commands are multiplexed for wireless IR transmission from said at least one IR microphone/controller; and
b. multiple separate redundant pluralities of IR transmission LEDs operable to concurrently wirelessly transmit said multiplexed audio signals and commands from said at least one IR microphone/controller.

Abstract
A presentation audio system with two dual-mode, dual-channel, wireless IR microphone/controllers that concurrently transmit multiplexed audio and command IR signals to IR sensors communicating to an amplifier that sends amplified audio to one or more speakers, responsive to the received commands. Each wireless IR microphone/controller includes a microphone and controller in a housing with manual controls and separate redundant groups of transmitting IR LEDs. The amplifier is controlled as to volume, audio sources selected, and control closure operation. First mode controls the audio of the IR microphone/controller that is set in the first mode and second mode controls all audio sources in the system. One manual control is a control closure that may be used to initiate a building alarm or for other purposes. A headset microphone jack enables use of the IR microphone/controller as an IR transmitter. A dual recharger usable vertically or horizontally is included.
