Configurations for
DMP 128
Applications #2 and #4, described in the
the user guide, utilize a DSP matrix processor with AEC to add additional microphones to
a conferencing system. Detailed instructions for using an Extron DMP 128 C model DSP
processor with the MediaPort 200 are provided in this section. A DSP Configurator template
file with pre‑configured routing and control points is available on the Extron website,
making it extremely easy to configure and use a DMP 128 C (herein referred to as
DMP 128). Troubleshooting will also be simplified, should it be necessary to contact Extron.
