1.1. This system consists of one or two 2.4 ghz digital transmitter(s) + one 2.4 ghz digital receiver or one 2.4 ghz digital receiver + digital stereo amplifier or one 2.4 ghz receiver + digital stereo amplifier + speakers (all-in-one unit). 1.2. Performed uninterrupted transmission and true regeneration of audio Signals to a level of cd quality sound. 1.3. Unlike other conventional analog systems available in the market, the frequency employed, intrinsic characteristics of the digital technology and aeis engineering know-how and skills incorporated into this system made it possible for this system to perform the following unique and convenient functions in addition to ordinary functions of Transmitting audio inputs wirelessly to a receiver unit. leave no or extremely minimal room for radio wave interferences for 2.4 ghz being far Away from most commercially used bands of uhf and by digitally pairing ids between a Transmitter and a receiver. This system allows users to select one of 99 id sets for Pairing between the transmitter and receiver. enable a mp3 player to transmit its output from the transmitter to the receiver to Entertain audiences. control the receivers output remotely and wirelessly from the transmitter. This unit Has a built-in volume control knob as an added convenience for users to be able to Control the output of a receiver by adjusting the knob. As a result, users do not have To run to the receiver to adjust the speaker volume when necessary. This functionality Is possible only because this system is a full digitally communicating unit between a Transmitter and a receiver. 1.4. This system can be a very useful and effective tool for the following occasions. lecturing at classrooms preaching at churches presenting at conferences entertaining at indoor or outdoor social/family gatherings
