Sada AV vysielača a prijímača DELOCK 65955 — Cat6/Cat6a HDMI extender, až do 3840×2160, káblový, napájanie Micro-USB-B

DELOCK 65955 is a wired AV transmitter and receiver set designed to extend HDMI signals over Cat6 and Cat6a cabling. The pair supports up to 3840×2160 (4K) resolution at 60 Hz and carries video, audio and IR control signals between a source and a display. The units are powered via Micro-USB B with an AC adapter (100–240 V, 50–60 Hz) and are supplied as a two-piece set in a compact black housing suitable for home AV, conference rooms, digital signage and fixed AV installations.

Advantages

The set transmits high-resolution 4K video and full audio over long distances using standard Cat6/Cat6a cable and supports HDCP. It provides an HDMI loop output on the transmitter to cascade the signal or to locally monitor the source. Infrared pass-through enables remote control of the source from the display location. The design supports Power over Cable (PoC) so only one device needs an external power supply while the other is powered through the network cable, and the screwable DC power connector improves reliability in permanent installations.

Suitable for

• Extending HDMI from PC, media player or set-top box to a remote display up to 50 m at 4K60
• Digital signage installations and video walls where a single cable run is preferred
• Conference rooms and lecture halls requiring a reliable wired AV link
• Installations needing IR remote control transmission between source and display

When it may not be suitable

This wired extender requires Cat6 or Cat6a cabling; it is not suitable where only wireless transmission is acceptable. For resolutions or refresh rates beyond 3840×2160 at 60 Hz the device may not support the required bandwidth. The set is intended for fixed installations and relies on a stable AC power source and proper network cabling for maximum distance performance.

Key specifications

• Maximum supported resolution: 3840 x 2160 pixels at 60 Hz
• Supported cable types: Cat6, Cat6a
• Maximum transfer distance: 50 m at 4K60; up to 70 m at 1080p
• Connectivity: wired HDMI extension over Ethernet cable with IR pass-through
• Power: Micro-USB B input, AC adapter operation 100–240 V, 50–60 Hz; supports Power over Cable (PoC)
• Physical dimensions (each unit): 61 mm (W) x 88 mm (D) x 18 mm (H)
• Colour: Black
• Quantity per pack: 2 units (transmitter and receiver)

How to use

Connect the HDMI output of the source device to the transmitter and the HDMI input of the display to the receiver. Use a single run of Cat6 or Cat6a cable between transmitter and receiver; observe the recommended maximum distances depending on resolution. Plug the AC adapter into one unit via the Micro-USB B power input; the second unit can be powered via PoC over the network cable. If required, connect the included IR emitter and receiver to enable remote control signals to pass between locations. The HDMI loop output on the transmitter can be used to connect a local monitor or cascade to another extender.

What to consider before purchase

• Verify available cabling: Cat6 or Cat6a required for specified distances and performance
• Confirm display and source support for 4K60 if you plan to use 3840×2160 at 60 Hz
• Check power outlet availability for the AC adapter and whether PoC will be used
• Ensure IR remote cabling placement if remote control functionality is needed

Recommendations

For reliable 4K60 transmission, use high-quality Cat6a cable and avoid running the cable near large electrical interference sources. When installing permanently, secure the screwable DC connector and test the IR placement before final mounting. For distances approaching the upper limits, test the system at the required resolution and refresh rate to confirm stable performance.
