Abstract
An apparatus comprises a volume-control user interface, a transmitter, an audio amplifier (having a corresponding amplification range), and a control circuit operably coupled to the foregoing components. This control circuit is configured to respond to a volume change made via the volume-control user interface that is within the amplification range of the audio amplifier by making a corresponding change to a volume level for an audio signal being transmitted by the transmitter. The control circuit is also configured to respond to a volume change made via the volume-control user interface that exceeds the amplification range of the audio amplifier by transmitting a volume-increase command.
