MediaPort 200 Audio Application Tutorial • Audio Application Setup 1

Audio Application

Setup

The MediaPort 200 is designed to integrate seamlessly into a variety of applications. This

section contains tutorials for how to set up the MediaPort 200 in the following applications:

• Application 1 – MediaPort 200 (standalone)

• Application 2 – MediaPort 200 + DSP matrix processor with AEC

• Application 3 – MediaPort 200 + hardware video codec

• Application 4 – MediaPort 200 + DSP matrix processor with AEC + hardware video

codec

In applications 2 and 4, specific inputs or outputs are defined for use with the Extron

DMP 128 C models as the external DSP matrix processor (herein referred to as “DSP

processor”). DSP Configurator template files with the routing and configurations described

are available for use with all DMP 128 C models, and can be downloaded from the Extron

website. These pre‑configured files facilitate and greatly simplify the integration of the

MediaPort 200 with Extron DMP 128 C model products. See section, Configurations for

DMP 128 on page 22 for more information on using the DSP Configurator template files.

Overview

This section contains a general discussion on MediaPort inputs and outputs and their

intended uses. All of the principals described in this section are put into practice in the

application setup tutorials that follow.

Line Inputs

The following MediaPort 200 line inputs are typically used for program audio:

• USB Playback — The MediaPort is the computer USB audio playback device.

• HDMI — Accepts 2‑channel PCM signals from this digital connection.

• Line Input (Analog) — Accepts balanced or unbalanced line level signals.

USB Playback Input

The local PC may be used as a program source via the USB connection. This is

independent of the far end USB Communication audio sent from the computer to the

MediaPort 200.

MediaPort 200 Audio Application Tutorial • Audio Application Setup 2

HDMI Input

The HDMI input may be fed from a camera, a computer, or from a switcher or other HDMI

source. The loop out may be connected to a local display, or to a hardware codec in

applications that utilize a hardware codec (such as Applications #3 and #4). The HDMI

source may be a video conference or document camera without audio, or may be another

program source such as a PC or switcher output that includes embedded audio. If the

HDMI input is used with a camera that includes microphone audio, the HDMI audio input

should be muted.

The HDMI input may alternatively be connected to a matrix switcher. In this case, the loop

out may be used to connect to a hardware codec. For additional flexibility, an output from

the matrix switcher may be connected to the hardware codec. Connecting an output from

the matrix switcher to the hardware codec allows for different content to be sent to software

codec and the hardware codec, as needed.

Line Input (Analog)

Connect an analog program source to the line input. This could be the output of a switcher,

or an auxiliary program source such as a CD/DVD player, mobile device, media player, etc.

These line inputs are mixed to the USB output and sent to the far end, and are also sent to

the analog line output. The analog line output path also mixes in the USB Communications

audio (from the far end), while USB audio output path does not. See section,

MediaPort 200 Signal Flow on page 13 for more information.

USB Communications Input

USB “Communications,” or far end audio, is mixed with the line inputs to the analog line

output for local sound reinforcement. It is also summed and sent by itself to the AEC Ref

Out. When the MediaPort 200 is used with a DSP processor, USB far end audio should be

muted to the line output, and received at the DSP processor from the MediaPort Ref Out

instead.

Mic Input

The mic input may be connected to a dynamic or condenser microphone that will serve

as the conferencing mic. Alternatively, a mic mixer—generally, a DSP processor with

AEC—may be connected to the mic input. The mic input is sent to the USB output to the

computer to be sent to the far end of a soft codec conference, but not to the line outputs.

The mic input is also sent to the Aux Output and can be connected to a hardware codec for

the application of soft codec + hardware codec conferencing (Application #3), or to a sound

reinforcement “voicelift” system if needed.

MediaPort 200 Audio Application Tutorial • Audio Application Setup 3

Line Output

The line output is used to connect to a local sound reinforcement system. All line input

program sources, plus the USB Communications audio from the far end, are mixed to the

line output. In an application that uses a DSP processor in conjunction with the MediaPort

200, the analog line output will be connected to the DSP processor as an AEC reference for

the program material, and then sent to local sound reinforcement from the DSP processor.

In this case, USB communications audio (far end) will be muted to the line output and sent

to the DSP processor via the AEC reference output (see section, Using the Mix Tab on

page 10 for more information).

USB Communications audio from the far end is always routed to the AEC Out. This is

intended for use with a DSP processor, so that far end USB Communications audio can

be used as an AEC reference in the DSP, and then sent to the local sound reinforcement

system from the DSP processor. When USB Communications audio is muted to the line

output, the line output will send only program audio to the DSP processor. This allows

program audio to be managed separately from USB Communications audio. Program audio

may also be used as an AEC reference, and either mixed to the same sound system as USB

Communications audio or sent to a separate sound system.

Ref/Aux Out

The AEC “Ref” output is used in conjunction with a DSP processor using multiple

microphones with distributed AEC (i.e., an AEC processor on every microphone channel).

Only USB far end audio is routed directly to the AEC reference output. Alternatively, the AEC

output can be used to send USB Communications audio to a separate sound system from

program audio mixed to the line output. In this case, USB Communications audio would be

muted to the line output.

The Aux Out contains only the mic input signal from the MediaPort 200. This facilitates

connecting both the MediaPort 200 and a hardware codec when the same mic applied to

the MediaPort 200 is to be simultaneously used as the mic source for the hardware codec.

Application 2 – MediaPort 200 with DSP Processor with AEC

This is an application for soft codec conferencing, where the MediaPort 200 operates in

conjunction with a DSP processing device with AEC (acoustic echo cancellation). The

MediaPort AEC Ref output sends far end USB communications audio to the DSP processor

as an AEC reference. The line output from the MediaPort 200 sends program audio to the

DSP processor, where it’s routed for AEC reference and for sound reinforcement. The send

to the sound reinforcement system, which includes program and far end audio, comes from

the DSP processor output.

MediaPort 200 Audio Application Tutorial • Audio Application Setup 6

Connect MediaPort 200 to the DSP matrix processor

1. Connect the line output of the MediaPort 200 to line inputs on the DSP processor

[DMP 128 Input 9 (“MP Program L”) and Input 10 (“MP Program R”)].

The MediaPort line output sends the program mix signal to the DSP processor. In this

application, select the “AEC Ref Only” radio button for USB Communications audio,

located on the Mix tab in PCS. This signal is used in the DSP processor as an AEC

reference on each microphone input, and also routed to the sound reinforcement

system from the DSP processor.

2. Connect the AEC Ref output of the MediaPort 200 to a line input on the DSP processor

[DMP 128 Input 11 (“MP Far End”)].

The AEC Ref output sends the USB Communications signal (far end audio) from the

MediaPort to the DSP processor. This signal is used in the DSP processor as an AEC

reference on each microphone input, and also routed to the sound reinforcement

system from the DSP processor.

3. Connect a line output on the DSP processor to the mic input of the MediaPort 200

[DMP 128 Output 3 (“To MP Mic In”)].

This line output sends a mix of the microphones connected to the DSP processor.

Connect from the DSP processor

1. Connect line outputs on the DSP processor to the local sound reinforcement system

[DMP 128 Output 1 (“SP Spkr L”) and Output 2 (“SP Spkr R”)].

This line output will contain a mix of the local program material routed from the

MediaPort Line Out plus the USB Communications audio that had been routed to the

DSP processor from the MediaPort AEC Ref Out.

Connect to the DSP processor

1. Connect up to eight microphones to DMP 128 Inputs 1 – 8. Once the microphone

types are selected, Extron Building Blocks can be used to configure the mic channels

for gain and processor settings (see the DMP 128 User Guide or DSP Configurator

Help File for information about Building Blocks).
