  • Page 25: Initialization

    Using ProManager Plus™ is possible creating a custom model based on Zero Latency DSP (included on M-Drive) or based on an additional Powersoft DSP-4. Once you have created and exported the custom Armonía Plugin, the loudspeaker equipped with M-Drive can be recognized and managed via ArmoníaPlus™ software.

  • Page 26: 2.Initialization Framework

    In order to initialize the DSP on board and external Powersoft DSP, the ProManager Plus™ proposes two approaches: Powersoft init or Custom init. The former initializes your DSP with default settings, while the latter initializes the DSP with your custom processing and it will allow ArmoníaPlus™ to identify your system as proprietary. As shown on the workflow, before directly proceeding with a custom initialization of the DSP, you are required to create a valid custom model for your product in which the presets –...
