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.
Features and Functions
High-performance 8 x 1 or 8 x 2 HDMI switcher
QuickSwitch HD switching technology
Handles HDMI with Deep Color, 3D, and 7.1 linear PCM or
high-bitrate encoded audio
Compatible with DVI and DisplayPort Multimode*
Supports video resolutions up to WUXGA 1920 x 1200 and
HD 1080p60
Detects and reports detailed video and audio input information
(Continued on following page)
* 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.

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.

Operations & Installation Guide – DOC. 6714B QuickSwitch HD HDMI Switcher: HD-MD8X1/HD-MD8X2 3
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.
