    Abstract: Embodiments of a configurable loudspeaker using a user orientable routing card that allows for multiple electrical drive modes in a non-powered loudspeaker system. The speaker has one or more drivers mounted in enclosure, an audio input interface configured to be coupled to an audio source through one or more amplifiers, and a connector interface configured to receive a routing card. The routing card is configured to be inserted in a first orientation to connect the audio input interface in a first operating mode with respect to driver selection and connection to the one or more amplifiers, and a second orientation to connect the audio input interface in a second operating mode with respect to driver selection and connection to the one or more amplifiers.

    Abstract: Embodiments are described for a hybrid amplification architecture that separates individual audio amplifier stages from the power supply and a simple two- or three-conductor bus that transmits both power and audio signal to a plurality of daisy-chained speakers to playback adaptive audio content in an expanded surround-sound environment including surround and overhead speakers or for use within professional live sound applications and/or distributed audio systems. A control unit generates digital audio and power and transmits both simultaneously over the bus to individual speaker units associated with each speaker. The speaker units recover the power decode the channel assignment to route the audio to the appropriate speakers.
