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.
