AV-lähetin ja -vastaanotin Kramer Electronics PT-871/2XR-KIT

The Kramer Electronics PT-871/2XR-KIT is a high-performance AV transmitter and receiver kit designed to extend HDMI signals over twisted-pair cable using DGKat™ 2.0 technology. The transmitter converts HDMI input into a DGKat™ 2.0 signal while the receiver converts the DGKat™ 2.0 signal back to HDMI. The kit supports 4K@60Hz (4:4:4) HDR with HDCP 2.2 and provides two-way power over twisted pair, enabling flexible installation with a compact form factor (62.2 × 51.8 × 24.4 mm).

Advantages

This kit supports uncompressed 4K@60Hz (4:4:4) with HDR and HDCP 2.2 compliance, allows two-way powering over twisted pair to simplify power distribution, and offers long-reach extension of HDMI signals up to 60 m at 4K@60Hz and up to 70 m at 4K@30Hz over Kramer shielded cables. The small enclosure and wired connectivity make it suitable for installations where space is limited and reliable signal transport is required.

Suitable for

• Extending 4K HDR HDMI sources to remote displays in meeting rooms and classrooms
• Integration into AV systems requiring HDCP 2.2 compatibility
• Installations that need two-way powering over twisted pair to reduce cabling
• Environments where a compact transmitter/receiver pair is preferred

How to use

Connect the HDMI source (player, PC, or media device) to the PT-871xr transmitter HDMI input. Use Kramer shielded twisted-pair cable to connect the transmitter to the PT-872xr receiver over the required distance. Connect the receiver HDMI output to the display. Provide power using the supplied AC adapter or enable two-way powering over the twisted-pair link according to the installation needs. Verify display resolution and EDID/HDCP negotiation on initial setup and adjust source or display settings if required.

Recommendations

For reliable performance at maximum resolutions, use Kramer shielded twisted-pair cable, keep cable runs within the specified distances (60 m for 4K@60Hz, 70 m for 4K@30Hz), and ensure both units receive proper power—either via the AC adapter or via the two-way powering feature.
