Connecting the MediaPort 200 to the DSP
1. Connect the analog Line output of the MediaPort 200 to line inputs on the DSP (DMP
input 9 and input 10). The MediaPort Line output sends the program mix signal to the
DSP.
2. Open PCS on the host computer and connect it to the MediaPort (see
Starting the PCS Software
3. On the PCS main window, click the

The DSP uses this signal as an AEC reference on microphone inputs and also routes it
to the sound reinforcement system.
5. Connect the Ref output of the MediaPort 200 to a line input on the DSP (DMP 128
input 11). The Ref output sends the USB communications signal (far end audio)
from the MediaPort to the DSP. The DSP uses this signal as an AEC reference on
microphone inputs, and also routes it to the sound reinforcement system.
6. Connect a line output on the DSP that contains the mic mix to the Mic/Line input of the
MediaPort 200 (DMP 128 output 3). This line output sends the MediaPort 200 a mix of
the microphones connected to the DSP.
