4K 60Hz Chainable HDMI Repeater/ Extender

  • Resolution up to 4K@60Hz 4:4:4.
  • Signal extension up to 20M.
  • Supports CEC Pass through.
  • Chainable with multiple HR01-4K6G for longer distance.


Chain multiple repeaters to endlessly expand for more flexibility.

High-quality video

4K 60Hz with a chroma sampling rate of 4:4:4, presenting high-quality pictures.

A regular HDMI cable can typically transfer the signal to 10M away, depending on the quality of the cable. However, SC&T's HR01-4K6G can send an HDMI signal without compression and compromising the native resolution. Furthermore, the repeater is a chainable device that allows you to chain an unlimited amount of the repeater with a power adapter for each piece. For each being added, it can extend the transmission distance for up to 40M for a 1080p/ 4K 30Hz HDMI video (20M from source to the repeater, and 20M from the repeater to a display) and 20M for 4K 60Hz video. It's an ideal solution for meeting rooms, classrooms, churches, and more.

Why You Should Use an HDMI Repeater

Limitations of an HDMI Signal

Signal Loss

An HDMI signal degrades as the distance goes further. Generally, 65 feet is considered the maximum reliable length for an HDMI signal and even shorter for a higher resolution video.


The signal is also vulnerable to interference caused by high-voltage electric lines, and electromagnetic devices. When it comes to an A/V environment, it always requires massive cabling and complicated A/V setups that are very likely to affect HDMI signals.

Types of Interference your monitor may encounter:

  • Grainy picture
  • Floating lines/waves
  • Horizontal stripes
  • Randomly going black


SC&T 4K 60Hz HDMI Repeater

HR01-4K6G is the solution that equalizes the degraded HDMI signal, stabilizing and sending it 65ft further without compression and compromising the native resolution. Compliant with HDMI 2.0, LPCM 7.1@192KHz, Dolby TrueHD, and DTS-HD MA, the HDMI repeater is granted to transfer superior visual and hearing experiences, making it a perfect suit for professional A/V projects.


It's also a chainable device that can endlessly extend an HDMI signal. Each piece requires an HDMI cable and power to get an additional 32~65ft (10~20M), depending on the video quality.
*when the distance exceeds 328 ft (100M), using a regular HDMI extender is recommended.

Highly Compatible & Flexible

The repeater can perfectly work with any HDMI device, such as HDMI switchers, distributors, matrices...etc, to unleash their best performances in corresponding applications. Also allowing making up the cable length mismeasurement planned before and making the connection just right with plug-and-play installation.



Workable with

With all kinds of devices, for example:

HDMI Distributor Amplifier - HD04-4K6G

Presentation Switcher - HUS03-4K6G

HDMI Matrix Switcher - HS04M-4K6G
  • Resolution up to 4K@60Hz 4:4:4.
  • Extends 4K 60Hz video for 20M and 1080p/ 4K 30Hz for 40M over HDMI cables.
  • Chainable with multiple HR01-4K6G for longer distances.
