Abstract: Apparatus allowing a performer on stage using a microphone to communicate privately backstage during a performance with minimum or unobservable interruption to the audience. A miniature switch on an attachment to the microphone handle when actuated via the communications channel operates a relay or switching device to transfer communications from the performer's microphone to a backstage intercommunication system while temporarily disconnecting the microphone from the public address system. The attachment constituting a minor extension to the microphone handle enabling a self contained battery and resistance network to provide operating current to a switching relay. One or more visual indicators signal operation of the apparatus to backstage personnel alerting them to a forthcoming performer message.
