Ultimate flexibility wireless system for remote audio effects pedals

A method for processing an audio signal by a main unit and a floor unit, the main unit comprising an audio input, an audio output, a main unit wireless transmitter and a main unit wireless receiver, and the floor unit comprising an effects send output, an effects return input, a floor unit wireless transmitter and a floor unit wireless receiver, the method comprising:

• routing the audio signal from the audio input to the main unit wireless transmitter;
• transmitting the audio signal from the main unit wireless transmitter to the floor unit wireless receiver;
• routing the audio signal from the floor unit wireless receiver to the effects send output;
• routing the audio signal from the effects return input to the floor unit wireless transmitter;
• transmitting the audio signal from the floor unit wireless transmitter to the main unit wireless receiver;
• and
• routing the audio signal from the main unit wireless receiver to the audio output selectively operating in a first audio control state and a second audio control state where one of the audio control states comprises the routing of the audio signal from the audio input directly to the audio output;
• wherein the floor unit further comprises a physically actuated switch;
• and further transmitting a control signal from the physically actuated switch to the main unit wireless receiver, and transitioning from one of the first audio control state and the second audio control state to the other one of the first audio control state and the second audio control state when the physically actuated switch is activated after having been deactivated.
