Product Development: PD04 - New Amplifier Requirements for Speaker Protection and Control

Presenter:
Joachim Schlechter

The rising demand for active speaker protection across all audio applications creates new challenges on the audio amplifier design. The amplifier is transforming more and more into a "smart" system integrating sensing capabilities, digital interfaces, and internal signal processing. To push nonlinear "green" loudspeakers in small enclosures to their physical limits, a higher peak power from the amplifier is desirable. At the same time, there is a growing need for higher overall efficiency and minimal battery power consumption. This tutorial is discussing current trends and coming requirements in amplifier design in conjunction with speaker protection and control.
