About this Guide
This guide discusses how to install, configure, and operate the Extron
MGP 641 xi Series processors.
Throughout the guide, the terms “MGP,” and “processor” are used interchangeably to refer
to either of the products.
About the MGP 641 xi Series Multi-Graphic Processors
The Extron MGP 641 xi Series are multi-window processors that scale and present up to
four 4K @ 60 Hz source signals on a single screen. They feature advanced Extron Vector 4K
scaling technology for high image quality. The HDCP 2.3-compliant processors include four
HDMI 2.0 inputs and an additional HDMI background input for presenting live, non-scaled
content behind source windows. The MGP 641 xi SDI model additionally has four SDI
inputs. HDMI and DTP 4K @ 60 Hz outputs deliver duplicate signals to local and remote
displays. Fully customizable window layouts, logo and video keying, and window transition
effects enhance presentation of the source content. Source and output rotation enable use
with portrait displays, and audio de-embedding simplifies integration. Configurations can be
saved as presets and recalled as needed.
The MGP 641 xi Series processors can be controlled and configured remotely using the
Extron Simple Instruction Set (SIS) commands via the RS-232, USB, or Ethernet LAN
connections, the Videowall Configuration Software (VCS) via an Ethernet LAN or USB, the
MGP 641 xi Series embedded web pages, and the front panel buttons and knobs.
Models
The MGP 641 xi Series consists of two models: MGP 641 xi and MGP 641 xi SDI. Both
models have four HDMI inputs and one live HDMI background input. The MGP 641 xi SDI
model has, in addition, four SDI inputs.
Both models have two outputs: one HDMI and one DTP3. On the front panel, both models
have one USB-C configuration port.

MGP 641 xi Series use DTP3 extension technology on the DTP output and support DTP
and DTP3 receivers.
• DTP receivers — The units are compatible with all products that contain DTP inputs.
• Transmission distance of 330 feet (100 meters) — Requires the connected
receiver to be 330 feet (100 meters) capable. Data rates up to 10.2 Gbps are
supported at this distance.
• Transmission distance of 230 feet (70 meters) — Requires the connected
receiver to be 230 feet (70 meters) capable. Data rates up to 6.75 Gbps are
supported at this distance. Data rates above 6.75 Gbps, up to 10.2 Gbps are
supported at 130 feet (40 meters).
• DTP3 receivers — The units are compatible with all products that contain DTP3
inputs. Data rates up to 18 Gbps are supported at 330 feet (100 meters).
Audio
Digital audio from any of the four windows or the background input can be de-embedded or
passed through as embedded digital audio. Multi-channel bitstream formats can be passed
to the HDMI and DTP3 outputs. Also, embedded two-channel PCM audio can be extended
over the DTP3 output or extracted as balanced or unbalanced stereo audio to the analog
outputs.
A single embedded multi-channel or 2-channel audio signal on an HDMI or SDI input is
passed through to be embedded on the local HDMI output and the DTP HDMI signal. If
the selected audio source is 2-ch LPCM (HDMI) or AES (SDI), it is also made available on a
local 5-pole captive screw connector and as over DTP analog audio. If the audio source is
multi-channel, the local analog connection and the over DTP audio signals are muted.

SDI Embedded Audio (xi SDI Model Only)
For the SDI inputs, specific audio channels can be selected to be heard on the analog
and HDMI outputs via SIS commands (see AES Audio Pair or Channel Selection on
page63) and VCS (see the VCSHelpFile). The 16 channels are divided into four groups,
each consisting of two channel pairs (four channels).
NOTES:
• Bitstream audio formats on the SDI inputs are not supported as de-embedded or
pass through audio.
• The default source selection is window 1, but all audio outputs are muted by default
to ensure audio is not passed through without being configured.
See Audio Configuration starting on page62 for information on the channels contained
within each group.

1. Mount the MGP to a rack using the pre-installed side mounting brackets (see
Mounting the MGP 641 xi Series Processor on page102). The MGP 641 xi Series
has a 1U high, full rack wide enclosure.
Alternatively, attach the four provided rubber feet to the bottom of the MGP and place
the unit in the desired location.
2. Connect HDMI or DVI (with an appropriate adapter) sources to the HDMI input
connectors (inputs 1 through 4) or
Connect SDI sources to the SDI input connectors (SDI model only) (see figure4, Bon
the next page).
3. If desired, connect a source to the HDMI live background connector (C). The MGP
windows are displayed in front of this unscaled background video source.
NOTE: You must set the output resolution to match that of the background source,
or the background video is not displayed. The refresh rates do not need to match.
4. Make the following output connections as needed:
• Connect an HDMI, or DVI with an appropriate adapter, display to the HDMI
output 1A connector (D).
• Connect a DTP endpoint, XTP matrix switcher, or HDBaseT compatible receiver
to the buffered DTP/XTP/HDBT output connector 1B (F). For cable wiring and
recommendations, see Twisted Pair Recommendations for DTP, XTP, and
HDBT Communication on page14.
5. Connect a balanced or unbalanced analog audio output device (such as a DSP device
or an amplifier) to the 5-pole captive screw AUDIO OUT connector (J) for 2-Ch audio
from the selected input. This connector is configurable via VCS (see the VCS Help File)
or SIS (see Audio Output Format commands on page62) as two discrete mono
outputs or as one stereo output.

6. If the MGP is to be connected to a computer or to a host controller for remote control,
connect an RS-232 cable from the host to the 5-pole REMOTE RS-232 rear panel
connector (see figure4, K) or to the front panel USB mini-B CONFIG port (see
figure9, A, on page 13). The default protocol for the RS-232 port is 9600 baud, 1
stop bit, no parity, and 8 data bits, with no flow control.
Alternatively, connect an RJ-45 network cable to the rear panel LAN port for remote
configuration and control.
7. Connect power to the MGP by plugging a standard IEC power cord (provided) from a
100 to 240 VAC, 50-60 Hz power source into the power receptacle (see figure4, A).
8. Apply power to all other devices.
