Abstract
Systems and methods are described for outputting audio information via both wired and wireless outputs from a in-flight or in-vehicle entertainment system. An audio output device can include a wireless transmitter and an audio output port. A transmission power of the wireless transmitter can be controlled via a processor based on a measured received signal strength indicator (RSSI) level of a connected slave device and a transmission power of the connected slave device.
