Abstract: A system for eliminating cables. The system includes a transmitter including an external input and a RF transmitter module; and a receiver including an RF receiver module and an external output.

Abstract: A system for wireless control of audio signal switching. The system includes a remote unit, having a physically actuated switch and a remote unit status indicator, and a main unit. The main unit includes a main unit transceiver and one or more relays which may switch the path of the audio signal or provide remote control of external devices, in response to input at the physically actuated switch. The main unit may send status updates to the remote unit, allowing the remote unit to display the current state of the main unit to a user at the remote unit.

Abstract: A system for providing wireless connections in configuring an instrument or microphone with audio effects, effects pedal boards, mixers, and other studio equipment. The signal from an audio source such as an instrument or microphone is connected to a main unit, from which it is transmitted via wireless link to a floor unit connected to one or more effects pedals or other studio equipment. After processing, the audio signal is returned via wireless link to the main unit and then routed to an amplifier.

Abstract: A system for wireless control of audio signal switching. The system includes a remote unit, having a physically actuated switch and a remote unit channel status indicator, and a main unit. The main unit includes a main unit transceiver and one or more relays which may switch the path of the audio signal or provide remote control of external devices, in response to input at the physically actuated switch. The remote unit may be programmed with effects patches, i.e., combinations of effects to be activated simultaneously, to enable the user to select a combination of effects with a single push of a button at the remote unit.

Abstract: A system for wireless operation of an expression pedal. In one embodiment a remote unit senses the position of an expression pedal and transmits the sensed expression pedal position information to a main unit. The main unit receives the sensed expression pedal position information and sets an adjustable element, to change an audio quality of an audio signal propagating through an external effects box, or of an audio signal propagating through the main unit.
