Digital Signal Processing (DSP)

The PWR-DSP3 amplifier is a plate amplifier with embedded Digital Signal Processing (DSP) controlled remotely over
Ethernet networks. Real time/live changes of the settings are saved automatically inside the flash memory of the
PWR-DSP3. The load/save feature also allows users to reload an existing configuration among multiple units.

The audio signal processing signal flow diagram is shown below.

The following section of this user manual will highlight settings available for each section.
