Audio Application
Setup
The MediaPort 200 can integrate seamlessly into a variety of applications. This section
contains instructions on how to set up the MediaPort 200 for the following applications:
•
•
•
•
Applications 2 and 4 include suggestions for specific inputs or outputs for use with
the Extron DMP 128 C Digital Matrix Processors models, including DMP 128 C AT,
DMP 128 C P, and DMP 128 C P AT as the external DSP matrix processor (referred to in
this guide as DSP processor).
Additionally, DSP Configurator template files with the routing and configurations described
are available for use with DMP 128 C model products and can be downloaded from
www.extron.com. These preconfigured files facilitate and greatly simplify the integration of
the MediaPort 200 with DMP 128 C model products.

Overview

This section contains a general discussion of MediaPort 200 inputs and outputs and
their intended uses. All of the principles described here are used in the application setup
procedures that follow.

Line Inputs

The following MediaPort 200 line inputs are typically used for program audio:
•
•
•
These line inputs are mixed to the USB output and sent to the far end and to the line output.
The analog line output signal path also mixes in the USB communications audio from the far
end, while the USB audio output path does not.
