Product Information

Full details

The Kramer PT-871/2XR-KIT is a high-performance AV transmitter and receiver set designed for extending 4K@60Hz (4:4:4) HDR HDMI signals over long distances using a single twisted-pair cable. It's ideal for professionals in AV installation, broadcasting, and corporate environments who need reliable, visually lossless video transmission with minimal latency. While it offers exceptional performance and flexible powering, users must ensure the use of Kramer shielded cables for optimal results.

FAQs

What is the maximum distance for 4K@60Hz (4:4:4) signal transmission?

The maximum distance for 4K@60Hz (4:4:4) resolution is up to 60 meters (200 feet) using Kramer shielded twisted-pair cables.

Can I use a standard Cat5e or Cat6 cable?

While standard Ethernet cables might work for shorter distances or lower resolutions, Kramer strongly recommends using their shielded twisted-pair cables (like Cat6a or Cat7) for optimal performance and to achieve the specified distances, especially for 4K@60Hz (4:4:4) signals. Using non-recommended cables may result in degraded video quality or reduced transmission range.

Does the kit include the necessary twisted-pair cable?

No, the PT-871/2XR-KIT does not include the twisted-pair cable. You will need to purchase a compatible Kramer shielded twisted-pair cable separately.

How does the 2-way powering work?

The kit supports Power over Cable (PoC) technology. The included AC adapter can be plugged into either the transmitter or the receiver, and the power is then sent over the single twisted-pair cable to power the other unit, eliminating the need for separate power supplies at each end.

What is DGKat™ 2.0?

DGKat™ 2.0 is Kramer's proprietary technology that enables the transmission of high-bandwidth HDMI signals, including 4K HDR and HDCP 2.2, over standard twisted-pair cables with visually lossless compression and near-zero latency.

Is the unit rack-mountable?

Yes, the units feature a compact, fanless design. Up to four units can be mounted side-by-side in a 1U rack space using the optional RK-4PT rack adapter.

What audio formats are supported?

The PT-871/2XR-KIT supports extending up to 32 channels of uncompressed digital stereo audio, including Dolby TrueHD and DTS-HD formats.

Troubleshooting

No video signal is transmitted.

Verify that both the transmitter and receiver are powered on. Check that the HDMI cables are securely connected at both ends. Ensure the twisted-pair cable is properly seated in the RJ-45 ports and is a compatible Kramer shielded cable. Confirm that the source and display devices are powered on and set to the correct input.

Video quality is poor or intermittent.

This is often due to using a non-shielded or low-quality twisted-pair cable. Replace the cable with a Kramer shielded twisted-pair cable (Cat6a or higher recommended). Check the cable for any physical damage. Ensure the resolution and refresh rate settings on the source do not exceed the maximum supported by the extender and cable length.

Device does not power on.

Confirm that the AC adapter is securely connected to the power port on one of the units and plugged into a working electrical outlet. Check if the LED indicator for power is illuminated. If not, try a different outlet or AC adapter.

HDCP error or content not displayed.

Ensure both the source device, the extender kit, and the display device support HDCP 2.2. The PT-871/2XR-KIT is HDCP 2.2 compliant, but the source and display must also be compatible. Try restarting the source and display devices.

Pros and Cons

Pros

Visually lossless 4K@60Hz (4:4:4) HDR transmission
Long extension distances up to 70m
Single cable for signal and 2-way power simplifies installation
Supports latest HDMI 2.0 and HDCP 2.2 standards
Near-zero latency for smooth video playback
Compact, fanless design for quiet operation and versatile mounting

Cons

Requires Kramer shielded twisted-pair cables for optimal performance
Maximum distance varies significantly with resolution and chroma subsampling
Does not include the necessary twisted-pair cable in the package
Limited to 18Gb/s bandwidth, which is standard for HDMI 2.0 but may be a consideration for future technologies.

Setup, Compatibility & Care

Setup:

Connect an HDMI source device (e.g., laptop, media player) to the HDMI IN port on the PT-871xr transmitter.
Connect an HDMI display device (e.g., monitor, projector) to the HDMI OUT port on the PT-872xr receiver.
Connect the two units using a single Kramer shielded twisted-pair cable (e.g., Cat6a or Cat7). Ensure the cable is securely connected to the DGKat RJ-45 IN port on the transmitter and the DGKat RJ-45 OUT port on the receiver.
Connect the included AC adapter to the power input on either the transmitter or receiver. The unit will supply power to the other unit over the twisted-pair cable.
Power on the source and display devices. The LED indicators on the units will show the status of the HDMI and DGKat connections.

Compatibility:

HDMI Standard: HDMI 2.0, HDCP 2.2.
Resolutions: Supports up to 4K@60Hz (4:4:4) and 4K@30Hz (4:4:4).
Cables: For optimal performance and maximum distance, Kramer strongly recommends using Kramer shielded twisted-pair cables. Other shielded cables may work but compatibility is not guaranteed.
Audio: Supports up to 32 uncompressed digital stereo channels.

Care:

Cleaning: Clean the exterior of the units with a soft, dry cloth. Avoid using liquids, solvents, or abrasive cleaners.
Ventilation: Ensure the fanless units have adequate airflow around them, especially if mounted in an enclosure or rack. Do not block ventilation openings.
Connections: Periodically check that all cable connections are secure.
