SpeaKa Professional SP-11562928 HDMI Extender Set PC-controllable 4K@60Hz 70m CAT6 Black

When a standard HDMI cable hits its length limit, this SpeaKa Professional extender set steps in with a 70-metre reach over CAT6 and a PC-controllable brain. It is not just a repeater — it carries 4K at 60 Hz, USB KVM, RS232 and power over the same cable, so you can manage a remote display and its source from one desk.

Highlights

• Transmits 4K (3840 x 2160) at 60 Hz up to 70 m over a single CAT6 cable
• Full HDMI 2.0 bandwidth with 18 Gbps and HDCP 2.2/1.4 support
• Built-in USB 2.0 KVM extension: control the source PC from the receiver side
• RS232 and USB control ports for PC-based switching, EDID management and automation
• Power over Cable (PoC) — only one side needs a power supply
• Metal housings in black for reliable 24/7 operation

In daily use

The sender sits next to your media player, PC or camera, while the receiver goes behind a TV, projector or monitor up to 70 metres away. Because the extender carries USB, you can plug a keyboard and mouse into the receiver and operate the source as if it were local. The RS232 port lets a control system or PC send commands for source switching, EDID copy and status monitoring. Automatic EDID management prevents resolution mismatches, and manual override is available for custom setups. With PoC, you only need one power adapter at either end — ideal for ceiling-mounted projectors or displays in meeting rooms, lecture halls and digital signage.
