MediaPort 200 with Exter
nal DSP with AEC
Connecting Inputs to the DSP
Connect up to eight microphones to DMP 128 inputs 1 through 8. After selecting the
microphone types, Extron Building Blocks can be used to configure the mic channels for
gain and processor settings (see the
DMP 128 User Guide
DSP Configurator Help
file for information on Building Blocks).
Connecting DSP Outputs
Connect line outputs on the DSP to the local sound reinforcement system (DMP 128 output
1 and output 2). This line output contains a mix of the local program material routed from
the MediaPort Line output plus the USB communications audio that was routed to the DSP
from the MediaPort Ref output.
DSP Routing for Application 1
Mic Inputs 1 – 8
•
Microphone inputs are routed to the Virtual Send A, using the “Include Automixing”
routing option.
•
From Virtual Return A, the Mic Mix is routed to Output 3. DMP 128 Output 3 is
connected to the MediaPort 200 Mic/Line Input.
•
In the DMP 128 AEC processing dialog, “AEC Ref (Virtual Return #H)” is assigned as
the AEC reference for mic inputs 1 – 8.
Program L/R Inputs 9 and 10
Program content comes from the MediaPort 200 Line Output L/R, which is a mix of the
USB Playback, HDMI, and Line Input signals.
•
MediaPort 200 Line Output L/R is connected to the DMP 128 Inputs 9 and 10 “MP
Program L/R.”
•
DMP 128 Inputs 9 and 10 are routed to Outputs 1 and 2, and then connected to a
stereo sound reinforcement system in the room.
•
DMP 128 Inputs 9 and 10 are routed to Virtual Send H for the AEC reference.
USB Communications Input 11
“Far end” audio from a soft codec conference is received at the MediaPort USB
Communications input and is sent to the MediaPort 200 Ref Out.
•
MediaPort Ref Out is connected to DMP 128 Input 11 “MP Far End.”
•
DMP 128 Input 11 is routed to Outputs 1 and 2, and then connected to the sound
reinforcement system in the room.
•
DMP 128 Input 11 is also routed to Virtual Send H for the AEC reference.
