The Crestron® 4K HDMI® over HDBaseT® Extender (HD-EXT4-C) delivers
professional-grade digital HD AV signal extension for use in the home,
classroom, auditorium, or corporate boardroom. Without any special setup
or configuration, the HD-EXT4-C enables the transmission of high­definition digital video and audio over wire runs up to 330 feet
(100 meters) using a single, low-cost CAT5e cable. 4K video is supported
over slightly shorter distances. For applications that include an analog
audio signal, the HD-EXT4-C can also handle stereo line-level audio over a
second cable.

[1,2]

The HD-EXT4-C is composed of one HD-TX4-C transmitter and one
HD-RX4-C receiver. These components are only sold as part of the
HD-EXT4-C package. For applications requiring direct interface to an
HDBaseT source or display device, please refer to the HD-TX3-C
and HD-RX3-C.

Robust Ultra HD Signal Extension

Using HDBaseT technology, the HD-EXT4-C allows for the extension of
uncompressed HDMI signals using inexpensive twisted pair cable

[1]

.
Without relying on signal-degrading compression or IP streaming, or
inferior HDMI signal boosting, HDBaseT reliably transports the full
resolution signal from source to display — intact and uncompromised.

The HD-EXT4-C handles video resolutions beyond HD including 4K Ultra
HD and 4K DCI. Full HD 1080p60 with 3D and Deep Color is supported over
any distance up to 330 ft (100 m), while 4K is limited to 230 ft (70 m) or

[1]

less

. Audio capabilities include support for high-bitrate 7.1 audio formats
like Dolby® TrueHD and DTS-HD Master Audio™ as well as uncompressed
linear PCM. In addition to HDMI, it is also compatible with DVI and
DisplayPort Multimode sources, and DVI display devices, using appropriate
adapters or interface cables

[3]

.

Legacy Audio Device Support

In addition to carrying digital video and audio, the HD-EXT4-C also provides
for the extension of an analog audio signal to support DVI devices (and
certain HDMI devices) that may not include or support an embedded digital
audio channel. Enabling the extension of analog audio simply requires an
additional twisted-pair type cable.

[2]

Uncompromised and Uncomplicated

Crestron HDMI over HDBaseT products afford a very dependable signal
extension solution that’s simple to implement. No special configuration
or programming is required — just connect your source and display and
enjoy high-quality HD video and audio from across the room — or the
other end of the house.

The HD-EXT4-C is composed of one transmitter and one receiver
(HD-TX4-C and HD-RX4-C, both included). The transmitter can be mounted
in a single-gang wall box, or attached to any flat surface or inside an
equipment rack. The compact receiver can be mounted discretely behind
a display device or wherever else it needs to go. Linking the two
components requires just one or two runs of CAT5e or Crestron

DM 8G® cable

[1,2]

. Crestron offers the cable, connectors, and crimp tool for
a complete, easy and reliable wiring solution. A range of professional AV
interface cables and wall plates is also available to complement the
HD-EXT4-C for a total custom installation solution.

Notes:

1. For the HDBaseT® connection between the HD-TX4-C transmitter and HD-RX4-C receiver,

use Crestron DM-CBL-8G DigitalMedia 8G™ Cable, Crestron DM-CBL DigitalMedia™ Cable,
Crestron DM-CBL-D DigitalMedia D Cable, or third-party CAT5e (or better) UTP or STP.
Maximum wire length between devices is 330 ft (100 m) for resolutions up to 1600x1200
and 1920x1200 (including 1080p60 and 2K). For higher resolutions (including 4K), maximum
wire length is 230 ft (70 m) using DM-CBL-8G, or 165 ft (50 m) using DM-CBL, DM-CBL-D, or
CAT5e. Shielded cable and connectors are recommended to safeguard against unpredictable
environmental electrical noise which may impact performance at resolutions above 1080p. All
wire and cables sold separately.

2. For the balanced analog “AUDIO” connection between the HD-TX4-C transmitter and

HD-RX4-C receiver, use dual-twisted pair shielded audio cable or quality CAT5 (or better) UTP
or STP. Crestron DM-CBL-8G DigitalMedia 8G Cable is recommended.

3. 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 cables available separately.

4. The power pack must be connected to the HD-RX4-C receiver. Power is passed to the

HD-TX4-C transmitter via the HDBaseT connection. Please note, the HD-TX4-C and HD-RX4-C
are not PoH compatible. They cannot be powered by, or supply power to, another HDBaseT
device. They may however be connected to such devices without risk of malfunction.

5. Supports 4K at 50/60 Hz with 4:2:0 color sampling.
