1 Speaker Charcterization

Advanced speaker modeling is essential to maximizing the performance of the selected speaker while still protecting it from damage. The speaker model can be obtained using the characterization process in PPC3 (request access). TI’s Smart Amp algorithm then uses this model to protect the speaker during operation while maintaining the loudest and highest quality audio. This section will walk through how to characterize a speaker in PPC3.

The linear parameters of the speaker can be obtained through the Characterization tab in the PPC3 software. Characterization of the speaker is done using the Learning Board 2, TAS2563EVM, PPC3-EVM-MB and PPC3 Software. Please refer to SmartPA Speaker Protection Algorithm for details on the algorithm used during the characterization process.

Note:

Please verify the device is set as default PC playback device and configure the jumpers for mono playback/characterization as described in TAS2563EVM User Guide before begin speaker characterization

In order to characterize the speaker, please setup the EVMs and the learning board according to the TAS2563 Quick Start Guide and reference to the following figure. The characterization results demostrated in this document is based on demo speaker ASE03008MR-LW150-R (8Ω, 1W).
