A vehicle sound system includes a subwoofer system having a subwoofer, a satellite amplifier for driving the subwoofer, a host amplifier for receiving an audio signal, a noise management processing unit for providing, to the host amplifier, information to be used for achieving a desired audio environment, a sensor for providing information to the noise management processing unit concerning the ambient audio environment, a control line between the satellite amplifier and the host amplifier for transmission of control signals to the satellite amplifier, and a signal line between the satellite amplifier and the host amplifier for transmission of audio signals to the satellite amplifier, the satellite controller being configured to cause a diagnostic signal to be placed on the control line, the diagnostic signal being indicative of an operating condition of the subwoofer system.
An apparatus for controlling an ambient audio environment, said apparatus comprising a vehicle sound system comprising a subwoofer system having a subwoofer, a satellite amplifier for driving said subwoofer, a host amplifier for receiving an audio signal, a noise management processing unit for providing, to said host amplifier, information to be used for achieving a desired audio environment, a sensor for providing information to said noise management processing unit concerning said ambient audio environment, a control line between said satellite amplifier and said host amplifier for transmission of control signals to said satellite amplifier, and a signal line between said satellite amplifier and said host amplifier for transmission of audio signals to said satellite amplifier, said satellite controller being configured to cause a diagnostic signal to be placed on said control line, said diagnostic signal being indicative of an operating condition of said subwoofer system.
A method of communicating between a host amplifier and a satellite amplifier in a vehicle sound system, said method comprising at said satellite amplifier, receiving a control instruction from said host amplifier via a communication link, receiving, from a subwoofer system, diagnostic information indicative of an operating condition of said subwoofer system, based on said information, generating a diagnostic signal indicative of said operating condition, and transmitting said diagnostic signal to said host amplifier on said communication link.
An apparatus for generating a sound field within a vehicle, said apparatus comprising a satellite amplifier, a host amplifier, a communication link between said satellite amplifier and said host amplifier for transmitting control instructions from said satellite amplifier to said host amplifier, and means for transmitting, on said communication link, diagnostic information indicative of an operating condition of a subwoofer system driven by said satellite amplifier.
