QuickSwitch HD™ HDMI Switchers: HD-MD8X1/2 • 1
QuickSwitch HD™ HDMI Switchers
Crestron HD-MD8X1/2
HDMI is the new standard for interfacing high-definition AV equipment, and it is
key to handling the latest HD video and audio formats. Crestron has designed its
QuickSwitch HD switchers to provide unparalleled performance, functionality, and
custom integration capability. The HD-MD8X1 and HD-MD8X2 support HDMI
1.3a w/Deep Color and HDCP, handling 1080p60 HDTV and WUXGA computer
resolutions, and multi-channel HD lossless audio.
QuickSwitch HD™ Technology
Crestron’s QuickSwitch HD technology minimizes switching latency that plagues
other HDMI switchers. As the move to digital takes hold, more and more movie
studios and television service providers are using HDCP (High-bandwidth Digital
Content Protection) to protect their DVDs, Blu-ray Discs, and broadcast signals
against unauthorized copying. Viewing the HDCP encrypted content in its full highdefinition format requires the source device to “authenticate” each display and signal
processor in the system through an HDMI connection before delivering an output
signal. Normally the authentication process occurs every time any HDMI signal is
switched, causing a complete loss of signal for up to 15 seconds.
QuickSwitch HD technology achieves very fast switching of HDMI signals by
maintaining a constant HDCP connection with each HDMI device in the system,
eliminating the need to re-authenticate each time a different source is selected.
EDID Format Management
With HDMI comes a variety of video and audio formats to keep track of, and
chances are not every device in a system supports all of the same formats. HDMI
attempts to resolve this confusion using EDID (Extended Display Identification
Data). When two HDMI devices are connected together, the receiving device (a
display or surround sound processor) uses EDID to announce its format capabilities
to the source device (a TV tuner or video player), which in turn configures itself to
output the most effective format that both devices can support.
Unfortunately, there is no guarantee that EDID will always choose the “preferred”
format, and often conflicts arise that can result in disappointing picture and sound
quality. The HD-MD8X1 and HD-MD8X2 take full advantage of EDID to prevent
conflicts, assessing the formats supported by each HDMI device in the system,
allowing the installer to assign only the combinations that work and provide the best
results. Input 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
touchpanel to allow custom functionality and enhanced diagnostics.
HDCP Key Management
Another aspect to HDCP is its use of “keys” to manage the handshaking that occurs
between any two devices. Every HDMI source device has a limit to how many
downstream devices it can support, determined by the number of HDCP keys it has
available. Rarely is that limit advertised or specified by the manufacturer or service
provider, so connect too many displays or processors and the source will simply stop
outputting a signal without warning.
To prevent such surprises, the HD-MD8X1 and HD-MD8X2 test the HDCP limits of
each HDMI source, allowing the installer to configure the system around any
limitations, or substitute a different component.
CEC Embedded Device Control
The primary objective of every Crestron system is to enable precisely the control
desired for a seamless user experience. The HD-MD8X1 and HD-MD8X2 provide
2 • QuickSwitch HD™ HDMI Switchers: HD-MD8X1/2
Operations Guide – DOC. 6714A
Crestron HD-MD8X1/2
QuickSwitch HD™ HDMI Switchers
an alternative to conventional IR and RS-232 device control by harnessing the CEC
(Consumer Electronics Control) signal embedded in HDMI. Through its connection
to the control system, the HD-MD8X1 and HD-MD8X2 provide a gateway for
controlling many devices right through their HDMI connections, potentially
eliminating the need for any dedicated control wires or IR probes. Through proper
CEC signal management, Crestron allows you to take control of each device as you
like.
Adagio® Media System Expansion
The HD-MD8X1 and HD-MD8X2 provide transparent input expansion for the
Crestron AMS, increasing its input capacity to 10 full-featured HDMI inputs with all
signal routing controlled right through the AMS's front panel and remote. Adding an
HD-MD8X1 or HD-MD8X2 to an AMS system is made simple using Adagio
Composer software.
Computer Compatibility
Besides handling every available HDTV format supported by HDMI, the
HD-MD8X1 and HD-MD8X2 also support computer resolutions up to 1920 x 1200
WUXGA, and are compatible with DVI and DisplayPort Multimode computer
signals using a suitable adapter or dongle (not included).
Audio Breakaway
Audio signals may be routed independent of video in the HD-MD8X1 and
HD-MD8X2, allowing listening to one source while viewing another. For instance,
listen to your favorite music from your media server while playing a video game or
surfing the Internet on screen.
Front Panel Controls
The HD-MD8X1 and HD-MD8X2 work right out of the box without requiring any
connection to a control system or computer, providing intuitive signal switching via
the 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 and HD-MD8X2
allow direct communication with any Crestron 2-Series 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 their many powerful features and capabilities, the HD-MD8X1 and
HD-MD8X2 are 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.

Installation
Ventilation
The HD-MD8X1 and HD-MD8X2 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. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the environment may be greater
than the room ambient temperature. Contact with thermal insulating materials should
be avoided on all sides of the unit.
Rack Mounting
The HD-MD8X1 and HD-MD8X2 can be mounted in a rack or stacked with other
equipment. Two “ears” are provided with the HD-MD8X1 and the HD-MD8X2 so
that they can be rack mounted. 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, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
•
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: 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.
NOTE: 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).
To install the ears:
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.

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-allowed depth in a signal path (from source to display) may create
problems with displaying of audio and video content. The HDCP specification states
that the maximum depth of devices between source and display is six. Some

Using Crestron Toolbox, the switcher can test HDMI sources and displays for
switching limitations due to HDCP keys. The number of HDCP keys specify the
number of display devices that can be connected to a source over HDMI using
HDCP authentication. For more information, refer to the Crestron Toolbox help file.
EDID
EDID is a piece of data that HDMI receivers use to indicate their capabilities to the
HDMI sources.
The HD-MD8X1 and HD-MD8X2 route 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 do this, the switcher reads the EDID information
from devices connected to the outputs and determines the video resolutions and
audio format to send to the inputs to program EDID on the inputs.
Using Crestron Toolbox, the switcher can be configured to use several different
algorithms to determine what EDID information is sent to each source:

Only resolutions that are available in all of the displays that are connected
will be transmitted to the source. This ensures that any video signal coming
in from the source will be able to be shown on all displays. If certain
resolutions are only available on a subset of the displays, they will be
omitted.
•
Manual
Use Crestron Toolbox to select which resolutions are transmitted to the
source.
“Best Common” is initially set to use information from all displays, but can be
modified to use information from just a subset of displays by deselecting them in
Crestron Toolbox.
By managing which displays are used for the EDID calculations, you can maximize
the resolution of each source while ensuring that the source can be shown on each
display where it is needed.
The EDID calculations also affect audio formats. Each HDMI receiver sends its
supported audio formats to the source in the following format:
<Format> <Maximum # of channels> <sampling freq supported>
For example, a 5.1channel audio processor may have the following audio EDID
information:
•
Linear PCM, 2ch, 32/44.1/48kHz
•
AC3, 6ch, 32/44.1/48kHz
•
DTS, 6ch, 32/44.1/48kHz
Under “Best Common”, the same rules apply to audio as video.

Failure to do so may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.

Calculate Power
QuickSwitch HD™ HDMI Switchers
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 daisychained on the run, the Cresnet power usage of each network unit to be daisychained 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
40,000
L<
RxP
Where: L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM 2 ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM 2 ))
P = Cresnet power usage of entire run (or chain)
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).
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One
twisted pair is the +24V conductor and the GND conductor and the other twisted
pair is the Y conductor and the Z conductor.
Strip and Tin Wire
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.
Add Hubs
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).
