About this User Guide

This guide contains information to install, configure, and operate the Extron Electronics
MPS 409, Media Presentation Switcher.

In this guide, the MPS 409 may be referred to as “MPS”, “MPS 409” or “switcher”.

About the MPS 409

The Extron MPS 409 is a multi video format Media Presentation Switcher for small
presentation systems. The MPS 409 integrates several video switchers into one product. The
MPS 409 is a 2x1 VGA and audio switcher, a 2x1 DVI-D video and audio switcher, a 3x1
HDMI and audio switcher, and a 2x1 composite video and audio switcher. The MPS 409 can
also function as a 9x1 video switcher and includes a mic/line input with phantom power,
mic audio ducking (talkover), executive front panel lockout, and a program audio output. In
addition it has the ability to combine DVI & HDMI inputs to create a 5x1 DVI/HDMI video and
audio switcher. The switcher includes EDID Minder® and provides HDCP compliance.

Features

• Multiple video inputs — Nine inputs include two VGA (or SVGA, UXGA, RGBHV,

RGBS, RGsB, or RsGsBs) inputs on 15-pin HD female connectors, two DVI (DVI-D only),
three HDMI, and two composite video.

• Multiple video outputs — Four outputs for simultaneous (in Separate mode), or one

at a time (in Single mode) display on VGA, DVI, HDMI, or composite video devices.

• EDID Minder — Automatically manages EDID – Extended Display Identification Data

communication between the display and connected DVI, and VGA input sources. EDID
Minder ensures that all sources power up correctly, whether or not they are actively
connected to the display device through the switcher output.

• HDCP compliance — Ensures display of content protected media and interoperability

with other HDCP compliant devices.

• Multiple audio inputs — Seven 3.5 mm female stereo input connectors include two

in the VGA group, two in the DVI group, and three in the HDMI group corresponding
to the video inputs. The composite video group includes two stereo RCA inputs
corresponding to the two composite video inputs.

• Multiple audio outputs — One 3.5 mm stereo output for each VGA, DVI, and HDMI

group, and one stereo RCA output for the composite video group, plus one 5-pole
captive screw connector for Program Audio Out.

MPS 409 • Introduction 1

• Program audio switcher — A four input, one output stereo audio switcher allows

the audio input of any video group to be selected for the program audio output, with
volume and mute control. The MPS 409 features balanced/unbalanced program audio
output on a 5-pole captive screw connector.

• Microphone/line input — One 3.5 mm captive screw connector is used for a

balanced/unbalanced Mic or Line level input. The input has an adjustment range of

-66 dB to +12 dB. The microphone input includes a Mute button for "talk-over", with
adjustable threshold and volume control.

• Front panel security lockout (Executive mode) — Prevents unauthorized use in

non-secure environments. Locks out all front panel functions except input selection and
program volume control to prevent unauthorized changes.

• RS-232 remote control — A rear panel RS-232 port enables control via a control

system. Extron Electronics Simple Instruction Set™ (SIS™) allows for quick and easy
programming.

• Rack-mountable — The 1U high, full rack width, metal enclosure is rack-mountable,

with supplied rack mounting brackets.

• Multiple switcher modes — Multiple switcher modes provide flexible signal routing

capabilities to address the varying system switching environments. Users can choose
among four switcher modes: Single, Separate, Single-combine, and Separate-combine.

о Single switcher mode — Allows one-touch switching. When one of the nine

inputs is selected, video and associated audio input signals are routed to the outputs
of its group; the selected audio is also routed to the program audio output. In this
mode, outputs of the other groups are muted.

о Separate switcher mode — Allows independent switching of any given group.

This effectively segregates switching operations so that the MPS 409 becomes four
separate video switchers. While operating in separate switcher mode the program
audio can be output from any group, while cueing up for another group, without
interruption.

о Combine switcher mode – Allows up to five HDMI and DVI source devices to

be routed to a single HDMI-enabled digital display. Audio from the corresponding
digital input, connected through the 3.5 mm stereo jack, is routed to the local and
program audio outputs. This mode can be used when the switcher is in Separate or
Single switcher mode.

• Front-panel Mic and Program Audio output volume controls — To streamline

audio setup, the MPS 409 features front-panel Mic and program audio output volume
controls which allow for easy and separate adjustment of Mic and program audio
volumes. This eliminates the need for audio preamplifiers in many system designs.

• Audio input gain and attenuation — Allows users to set the level of audio gain and

attenuation for each input channel so that there are no noticeable volume differences
when switching between sources.

• Mic talk over — The talk over feature automatically reduces program audio when it

detects a microphone signal. This eliminates the need for a separate stand-alone audio
ducking processor. The talk over level is adjustable via the RS-232 control.

• HDMI 1.3 compatible — Supports HDMI 1.3 specification features, including data rates

up to 6.75 Gbps, deep color, auto-lip sync, and HD lossless audio formats.

• Audio breakaway — Provides the capability to break an audio signal away from its

corresponding video signal and route to the program audio output, allowing the audio
channels to be operated as a separate switcher.

MPS 409 • Introduction 2

Projector

• +48V phantom microphone power — Powers a condenser microphone.

• Provides +5 VDC, 250 mA power on the HDMI and DVI outputs for external peripheral

devices

• Internal universal power supply — The 100-240 VAC, 50-60 Hz, international power

supply provides worldwide power compatibility.

MIC PROGRAM AUDIO

The MPS switcher can be connected to as many as nine input devices and four output
displays plus an audio amplifier. It operates in one of four switching modes: single (the
default), separate, single-combine, or separate-combine.

The functions of the front panel controls are described in the following sections. Each input
group; VGA/YUV, DVI-D, HDMI, and composite, have one video and one audio output each.
The output is switchable only between the inputs of the corresponding group, except in
combine mode.

Although the wiring and connection of the switcher are identical, the four modes operate
differently.

Switcher Operating Modes

The switcher operating modes are:

• Single switcher (default) mode emulates one switcher with 9 inputs (9x1).

• Separate switcher mode allows the four groups of inputs (DVI, HDMI, VGA, Composite

video) to be used as individual switches, creating four independent switchers.

• Single-combine mode operates exactly as the normal single mode except the three

HDMI and two DVI inputs are output on the HDMI output.

• Separate-combine mode operates exactly as the normal separate mode except the three

HDMI and two DVI inputs are output on the HDMI output.

NOTE: The switcher does not convert signal formats between VGA and DVI/HDMI

nor will it scale or convert between other input formats.

View Mode

The current switcher mode can be determined by observing the input LEDs. If the unit is
in separate switcher mode, up to four input LEDs can be lit (one in each group). In single
switcher mode only one input LED at a time is lit.

To view the current switcher mode, press and hold the Mode button (VGA/YUV #1) for more
than 3 seconds.

Input Selection — Separate Switcher Mode

There are four input selection groups on the front panel: VGA/YUV, DVI, HDMI and
(composite) Video. These groups correspond to the four independent A/V switchers (in
separate switcher mode) available.

Each input group has two (three for HDMI) numbered input selection buttons, allowing
selection from among the input sources in that group.

The output of each of the four groups is always active and the selected input audio/video
is available on each group’s output. Program audio output is taken from the most recently
selected input. That group (input) is indicated by a flashing LED, while the other groups are
indicated by solid LEDs. See Program Audio on page 15 for more details.

In the example below each group has an input selected. In addition, the blinking LED
indicates which input audio is also routed to the program audio output.

MIC PROGRAM AUDIO

Combine mode switches a selected HDMI/DVI input to the HDMI output, deactivating the
DVI audio and video outputs. This enables the MPS 409 to function as one 5x1 HDMI/DVI
and audio switcher, adding VGA/YUV and Video inputs. Combine mode can be used
whether the switcher is in separate or single switch mode. All other inputs and outputs
function according to the selected switcher mode.

Input selection — Single-combine mode

In single-combine mode, the front panel input selection LEDs operate the same as standard
single mode; a single lit LED indicates the current input selection.

Input selection — Separate-combine mode

In separate-combine mode, only one input selection is allowed from the HDMI/DVI groups
along with a single input selection from the VGA/YUV group and another from the video
group. So there will only be three front panel LEDs lit in combine mode rather than four
when in separate switcher mode.

Front Panel Security Lockout (Executive mode)

To prevent unauthorized configuration changes, executive mode limits front panel access.
Control and monitoring are still available using the rear panel RS-232 or front panel USB port
and the control software. The front panel Exec Mode LED is lit when either lockout mode is
active.

Executive mode contains two levels:

• Mode 1 locks out the Mic Mute and Mic Volume control. When active, if mic control or

mute are attempted via the front panel, the mic mute LED will flash once.

• Mode 2 locks all front panel functions except Executive mode. When any adjustment is

attempted via the front panel, all front panel LEDs flash once.

To toggle through the executive modes:

1. Press and hold the mode button for more than 3 seconds,

2. Press the HDMI input 1 button to toggle through the executive modes.
a. If executive mode is not active (Exec mode LED off), the switcher toggles to

executive mode 1, the Mic Mute LED flashes three times, and the exec mode LED
turns on. Release both buttons to enter executive mode 1.

b. If already in mode 1, the switcher toggles to mode 2 and the exec mode LED

remains on. All front panel LEDs flash three times. Release both buttons to enter
executive mode 2.

c. If in mode 2, the switcher exits executive mode and turns off the Exec mode LED.

Release both buttons to exit executive mode.

Audio Gain and Attenuation Adjustments

Individual audio inputs can be adjusted over a range

Front Panel LEDs

of -18 dB to +24 dB using the program audio mute
button and program audio volume control knob.
These adjustments can be used to normalize
the input audio levels so that output volume is
consistent for all inputs.

The front panel input LEDs provide a status of
the current input gain/attenuation levels. When
adjusting the audio level, the LEDs used for inputs
1-8 (VGA inputs 1-2, DVI inputs 1-2, HDMI inputs
1-3, and video input 1) function as indicators of the
current audio level for the selected input as shown
in the table.

The LED input associated with video Input 2
functions as an indicator of gain (+) or attenuation
(–). If Input LED 9 (video input 2) is off, audio is
at a positive level (gain). If the LED is on, audio is
negative (attenuated).

To adjust the input audio level from
the front panel:

1. Press and hold the Program Audio Mute AND

Mic mute buttons for 3 seconds. The two Mute
LEDs flash three times.

2. Press the input button for the audio to be

adjusted. If no input button is pressed, the
switcher times out and exits audio level
adjustment mode.

3. Once the input button is pressed, the front

panel input LEDs indicate the current gain or
attenuation setting. Factory default is 0 dB (all
LEDs off). Rotate the Program volume knob
clockwise to increase and counterclockwise to
decrease the audio level. The front panel LEDs
display the level setting as the knob is adjusted.

4. Once the desired level is achieved, to adjust

another input, select it within 3 seconds. If
audio adjustments are complete:

a. Do not press any front panel buttons for at

least 3 seconds to exit the gain/attenuation
mode, or

b. Press the program audio and Mic mute

buttons to exit the gain/attenuation mode.

At any time during the adjustments, if front panel
buttons are not pressed or the program knob is not
rotated for 3 seconds, the switcher times out and

PROGRAM AUDIO

Mic on/off

Mic volume and mute are controlled from the front panel. The Mic mute button toggles the
Mic input on or off. The corresponding red LED illuminates when Mic volume has been shut
off (muted).

When the Mic input is enabled it is mixed with the program audio output. Mic volume is
a stepped encoder, adjusted at a rate of 1 dB per step of the control. Clockwise rotation
increases and counterclockwise decreases the Mic volume.

MIC

MUTE

Figure 17. Mic Volume and Mute

Talk-over

The MPS 409 also features talk-over to automatically reduce program audio volume when
microphone audio is present allowing the microphone audio to be heard more intelligibly.
When the switcher detects an audio signal from the Mic input, it immediately reduces or
"ducks" the program audio volume. When microphone audio is not detected for a period of
one second, it increases the program audio level at a rate of 3 dB per second until it reaches
the original volume level.

The program audio can be ducked from 0-30 dB (default is 6 dB), adjustable through
software control only. The Mic level threshold where ducking is initiated is adjustable from
0-15 dB through software control only. See Mic talk-over threshold on page 24 .

Mic volume

After turning on (unmuting) the Mic input, use the Mic volume control knob to adjust the
volume of the microphone output. When the control knob is turned, volume increases at a
rate of 1 dB per step. The program audio level has no affect on Mic volume.

Setting mic talk-over threshold

Microphone threshold and program audio ducking levels can only be adjusted using RS-232
control. See SIS Programming and Control on page 20 for more information.

1. Adjust program audio for nominal listening levels.

2. Turn on the microphone by pressing the Mic Mute button.

3. Speak into the microphone in a normal voice. The main program level should drop

immediately.

a. If the microphone consistently cuts off the beginning of speech, or cuts out

sections of audio, adjust the threshold level via RS-232 control. See Mic talk-over

threshold on page 24

b. If the program level is too high during talk-over, but is the proper level for times

where talk-over is not active, see Program audio ducking level in talk over

mode on page 24.

4. Stop speaking into the microphone. The main program audio should gradually increase

to the previous level within 2-4 seconds. If not, increase the threshold level. See Mic

talk-over threshold on page 24.

MPS 409 • Operation 17

EDID Minder

The DVI and VGA/YUV groups feature EDID Minder, ensuring that each input source reads
the EDID of the output display even when not selected. The result is the video source powers
up properly and reliably outputs content when selected. The EDID remains in the selected
mode (automatic or user assigned) even after loss of power.

The DVI group does not support HDCP by default. In order to support HDCP, EDID Minder
must be disabled. EDID Minder can be disabled for the DVI group using SIS commands.

Automatic Mode — If an output display has not been connected, a default EDID file is
placed on the VGA and DVI inputs according to the following table:

Input Group Default EDID

VGA 1024 x 768 @ 60 Hz
DVI 1024 x 768 @ 60 Hz

Figure 18. Default EDID Resolutions

When a display is connected to the group output, the EDID of that display device is read and
replaces the default EDID on each input. The EDID remains even if the display is removed.
If a different display is connected or a user assigned EDID is selected, the previous EDID is
overwritten.

NOTE: When the HDMI/DVI combine mode is enabled at the same time EDID Minder

is enabled on the DVI inputs, the EDID will be updated with the HDMI output
device EDID.

MPS 409 • Operation 18

User assigned EDID Mode — Using SIS commands, an EDID file can be selected from a
table of 19 EDID files. One additional EDID file location is reserved for user-loaded EDID files
for the VGA and DVI groups. Once a user assigned EDID is chosen, the switcher stores it at
the inputs and no longer polls for the EDID of a connected display. The chart below lists the
native resolution of each factory EDID file and timing characteristics associated with each.

USB configuration port. SIS commands consist of one or more characters per command field.
They do not require special characters to begin or end the command character sequence.
Each response to an SIS command ends with a carriage return and a line feed (CR/LF = ]),
which signals the end of the response character string. A string is one or more characters.

MPS Switcher-initiated Messages

When a local event occurs, such as a front panel operation, the MPS switcher responds
by sending a message to the host. The MPS 409-initiated messages are listed below
(underlined).

Boot-up messages

(c) Copyright 2010, Extron Electronics, MPS 409, Vx.xx

The copyright message is initiated by the switcher when it is first powered on. Vx.xx is the
firmware version number.

]

Status change messages

The switcher-initiated status change messages are a result of front panel operations (actual
or software-simulated). The status change messages are the same as switcher responses to
certain commands. See the last column of the command/response tables on the following
pages.

MPS Switcher Error Responses

When the MPS switcher receives an SIS command and determines that it is valid, it performs
the command and sends a response to the host device. If the switcher is unable to perform
the command because the command is invalid or contains invalid parameters, it returns an
error response to the host. The error response codes are as follows:

E01 ] — Invalid input channel number (too large)

E10 ] — Invalid command

E13 ] — Invalid value (out of range)

Command/Response Table

Using the Command/Response Table

The command/response table is shown on the following pages. Lower case characters are
acceptable in the command field only where indicated. Symbols are used throughout the
table to represent variables in the command/response fields. Symbol definitions and an
ASCII-to-hexadecimal (HEX) conversion table are shown below. Command and response
examples are shown throughout the command/response table.
