Abstract:
1. A method of operating an adapter comprising a first audio circuit and a second audio circuit independent of the first audio circuit, the adapter configured for connecting an electronic device, a first accessory, and a second accessory, the method comprising: at the adapter, receiving a first command signal from the first accessory and receiving a second command signal from the second accessory; at the adapter, generating control signals, with a control circuitry, by processing the first and the second command signals, wherein a first control signal, associated with the first command signal, is used to modify a gain value of the first audio circuit, a second control signal, associated with the second command signal, is used to modify a gain value of the second audio circuit independent of the first audio circuit, and a third control signal is used to modify an operation of the electronic device; sending the first control signal to the first audio circuit and the second control signal to the second audio circuit; sending the third control signal to the electronic device; and at the adapter, adjusting, with the control circuitry, the gain values of the first and second audio circuits in accordance with the first and second control signals, respectively.
