Crestron HD-MD8X1/HD-MD8X2 QuickSwitch HD HDMI Switcher
QuickSwitch HD HDMI
Switcher: HD-MD8X1/
HD-MD8X2
Introduction
QuickSwitch HD® switchers from Crestron® enable high-performance HDMI® signal
selection while delivering fast, trouble-free switching of all DVD and Blu-ray Disc
players, HDTV receivers, media servers, game consoles, multimedia computers,
surround processors, and high-definition displays in a system. The HD-MD8X1
features eight HDMI inputs and a single HDMI output to feed a video display or
processor. The HD-MD8X2 features eight HDMI inputs and two independently
switchable HDMI outputs to feed two separate displays or to support a single display
that has built-in PIP capability.
For simplicity within this guide, the term “HD-MD8X1/2” is used except where
noted.
HDMI is the standard for interfacing high-definition AV equipment and is key to
handling the latest HD video and audio formats. Providing unparalleled performance,
functionality, and custom integration capability, the HD-MD8X1/2 supports HDMI
with HDCP, Deep Color, and 3D, handling 1080p60 HD video and WUXGA
computer resolutions as well as multichannel HD lossless audio.

QuickSwitch HD Technology
Handling high-definition digital media means handling HDCP (High-bandwidth
Digital Content Protection), the encryption scheme that content providers use to
protect their DVDs, Blu-ray discs, and broadcast signals against unauthorized
copying. Viewing HDCP encrypted content requires a source device to
“authenticate” each display and signal processor in the system and issue each one a
“key” before the content can be viewed. Ordinarily, this causes a complete loss of
signal for up to 15 seconds each time a new source or display is selected anywhere in
the system. In addition, every source device has a limited number of keys available;
therefore, if too many displays are connected, the source stops outputting a signal
without warning. Crestron QuickSwitch HD, however, manages the keys for every
HDCP-compliant device in the system, maintaining continuous authentication for
each device to ensure fast, reliable switching.
®
EDID Format Management
With HDMI comes a multitude of confusing video and audio formats to keep track
of, and chances are that not every device in a system supports all of the same
formats. The HD-MD8X1/2 eliminates any conflicts by managing the EDID
(Extended Display Identification Data) that HDMI devices use to communicate their
capabilities. Via Crestron Toolbox™ software, the format and resolution capabilities
of each device can be assessed, allowing the installer to configure EDID signals
appropriately for the most desirable and predictable behavior. Signal information
such as resolution, frame rate, aspect ratio, color depth, and audio format can also be
sent to the control system and displayed on a touch screen to allow custom
functionality and enhanced diagnostics.
High-Definition Scaler Option
High-performance scaling capability can be added to the HD-MD8X1/2 using the
optional HD-SCALER (sold separately). The HD-SCALER features fully automatic
operation and is compact enough to install at the display location, ensuring an
optimal image regardless of the source that is selected. It also provides analog video
and audio inputs to accommodate additional analog sources.

Crestron HD-MD8X1/HD-MD8X2 QuickSwitch HD HDMI Switcher
Computer Compatibility
Besides handling every available HD format supported by HDMI, the
HD-MD8X1/2 also supports computer resolutions up to 1920 x 1200 WUXGA, and
is compatible with DVI and DisplayPort Multimode computer signals using a
suitable adapter or dongle*.
Audio Breakaway
Audio signals may be routed independently of video in the HD-MD8X1/2, allowing
listening to one source while viewing another. For instance, listening to favorite
music from a media server is possible while playing a video game or surfing the
Internet on screen.
Front Panel Controls
The HD-MD8X1/2 works out of the box without requiring any connection to a
control system or computer, providing intuitive signal switching via its front panel.
The front panel is great for everyday use, or may be used just for initial system
testing. Front panel buttons may be locked out to prevent unauthorized tampering or
accidental switching, while the LED indicators remain active to show signal routing
status. The input and output controls can be labeled easily using Crestron Engraver
software or standard 3/8" (10 mm) tape labels.
Native Crestron Control
Via the choice of Cresnet® or high-speed Ethernet, the HD-MD8X1/2 allows direct
communication with a Crestron control system for a fully integrated signal routing
solution as part of any high-end home theater, boardroom, classroom, or command
center system.
Easy Setup
Despite its many powerful features and capabilities, the HD-MD8X1/2 is simple to
set up using Crestron Toolbox software. The Toolbox setup tool allows the installer
to view information about each HDMI device and easily make intelligent choices to
ensure a reliable system setup.
* HDMI IN requires an appropriate adapter or interface cable to accommodate a DVI or DisplayPort
Multimode signal. HDMI OUT requires an appropriate adapter or interface cable to accommodate a
DVI signal. CBL-HD-DVI interface cable sold separately.

Installation
Ventilation
Rack Mounting
The HD-MD8X1/2 should be used in a well-ventilated area. The venting holes
should not be obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Contact with thermal insulating materials should be avoided on all sides
of the unit.
The HD-MD8X1/2 can be mounted in a rack or stacked with other equipment. Two
“ears” are provided with the HD-MD8X1/2 for rack mounting. These ears must be
installed prior to mounting. Complete the following procedure to attach the ears to
the unit. The only tool required is a #2 Phillips screwdriver.
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, observe the following guidelines:
When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: Observe the following guidelines when installing equipment in a rack:
Elevated Operating Ambient Temperature - If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of airflow required for safe operation of the equipment is
not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven mechanical
loading.
Circuit Overloading - Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (e.g., use of power strips).
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.

To install the ears:
CAUTION: To prevent equipment damage, use only the rack ears Crestron
provides for this device.
1. There are screws that secure each side of the HD-MD8X1/2 top cover.
Using a #2 Phillips screwdriver, remove the three screws closest to the front
panel from one side of the unit. Refer to the diagram following step 3 for a
detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
by the screws in step 1.
3. Secure the ear to the unit with three screws from step 1 as shown in the
following diagram.
Ear Attachment for Rack Mounting
Stacking
Use Cover Screws
4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the
opposite side.
Four “feet” are provided with the HD-MD8X1/2 so that if the unit is not rack
mounted, the rubber feet can provide stability when the unit is placed on a flat
surface or stacked. These feet should be attached near the corners prior to the hookup
procedure.
NOTE: No more than two HD-MD8X1/2 units should be stacked.

weighing less than 100 pounds tends to crumple while sliding in, while paper
weighing more than 100 pounds may not fit.
HDCP Signal Path
Sources using HDCP limit the number of display devices it can transmit to while
simultaneously limiting the depth of devices in the signal path. Too many devices or
greater than the allowed depth in a signal path (from source to display) may create
problems with the display of audio and video content. The HDCP specification states
that the maximum depth of devices between source and display is six. Examples are
provided in the following diagram.

EDID
EDID is a data structure that HDMI receivers use to indicate their capabilities to the
HDMI sources.
The HD-MD8X1/2 routes HDMI signals from any of the eight video inputs to one or
two (HD-MD8X2 only) output channels. According to the HDMI standard, HDMI
sources are expected to only deliver audio and video formats that are supported by
the destination.
To configure video/audio EDID, use the DMTool in Crestron Toolbox. The DMTool
allows the EDID configuration to be set manually while ensuring that the EDID is
accurate. For detailed information about configuring video/audio EDID, refer to the
Crestron Toolbox help file.

Uploading and Upgrading
Crestron recommends using the latest programming software and that each device
contains the latest firmware to take advantage of the most recently released features.
However, before attempting to upload or upgrade, it is necessary to establish
communication. Once communication has been established, files (for example,
programs or firmware) can be transferred to the control system (or device). Finally,
program checks can be performed (such as changing the device ID or creating an IP
table) to ensure proper functioning.
NOTE: Crestron software and any files on the Web site are for authorized Crestron
dealers and Crestron Service Providers (CSPs) only. New users must register to
obtain access to certain areas of the site (including the FTP site).

Operations & Installation Guide – DOC. 6714B QuickSwitch HD HDMI Switcher: HD-MD8X1/HD-MD8X2 23
To ensure optimum performance over the full range of the installation topology, use
Crestron Certified Wire only. Failure to do so may incur additional charges if
support is required to identify performance deficiencies because of using improper
wire.
QuickSwitch HD HDMI Switcher Crestron HD-MD8X1/HD-MD8X2
Calculate Power
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system
(www.crestron.com/calculators
).
When calculating the length of wire for a particular Cresnet run, the wire gauge and
the Cresnet power usage of each network unit to be connected must be taken into
consideration. Use Crestron Certified Wire only. If Cresnet units are to be
daisy chained on the run, the Cresnet power usage of each network unit to be
daisy chained must be added together to determine the Cresnet power usage of the
entire chain. If the unit is home-run from a Crestron system power supply network
port, the Cresnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be used in the
following equation to calculate the cable length value on the equation’s left side.
Cable Length Equation
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM ))
P = Cresnet power usage of entire run (or chain)
2
2
L <
40,000
Where:
R x P
Make sure the cable length value is less than the value calculated on the right side of
the equation. For example, a Cresnet run using 18 AWG Crestron Certified Wire and
drawing 20 watts should not have a length of run more than 333 feet (101 meters). If
Cresnet HP is used for the same run, its length could extend to 1250 feet (381
meters).
Strip and Tin Wire
Add Hubs
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One
twisted pair is the 24 and G pair and the other twisted pair is the Y and Z pair.
When daisy chaining Cresnet units, strip the ends of the wires carefully to avoid
nicking the conductors. Twist together the ends of the wires that share a pin on the
network connector and tin the twisted connection. Apply solder only to the ends of
the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the number of
Cresnet devices on a network exceeds 20 or when the combined total length of
Cresnet cable exceeds 3000 feet (914 meters).
