Professional 4K Video Distribution Over Long Distances Without Compromise

In installations where reliability is the only acceptable parameter, the CT378/11/1 extender represents the benchmark. Utilizing HDBaseT technology, this device enables the convergence of Ultra HD video, PoC power, bidirectional IR, and RS232 over a single network cable, eliminating the bottlenecks of traditional HDMI systems or IP solutions prone to compression and latency.

Technical Analysis and Advantages

  • 🛡️ HDBaseT 18Gbps Standard: Supports the full HDMI 2.0 standard. Manages 4K@60Hz streams with RGB and YCbCr color space (Deep Color), ensuring absolute color fidelity for 4K Blu-ray sources and professional broadcast signals.
  • 🔌 PoC (Power over Cable) Technology: The entire system requires only one power supply connected to the TX unit. The receiver receives the necessary power directly via the Cat.6 cable, drastically simplifying installation behind monitors or projectors where space is limited.
  • 🔧 HDMI Loop Out & Monitoring: The transmitter integrates a local HDMI output for real-time source monitoring, eliminating the need for external splitters and reducing potential points of failure in the video chain.
  • 🔄 Total Remote Control: Bidirectional management of IR signals and the RS232 serial port allows for complete integration with home automation systems or simple management of sources from the remote station.
  • 🔊 Lossless Multichannel Audio: Full compatibility with LPCM 8ch, Dolby TrueHD, and DTS HD Master Audio at 192 kHz / 24bit, for sound reproduction faithful to the original track.

💡 Expert Advice:

In support, we often see HDBaseT extenders that "drop" the signal or don't reach the declared distance. From experience, I can tell you that the secret is in the cable: never use CCA (copper-clad aluminum) cables. To cover 120m in 4K, exclusively install a Cat.6a or Cat.7 S/FTP cable with a pure copper conductor (OFC). Also, remember that HDBaseT is not IP: do not try to connect it to a network switch; the connection must be direct to avoid irreversible damage to the chipsets.

Quick FAQs

Can I use a Cat.5e cable?
Yes, but the maximum distance and 4K signal stability might be significantly reduced. For professional installations, we always recommend Cat.6 or higher.

What does Bidirectional IR mean?
It means you can control the decoder from the TV (remote) or, conversely, manage the display from the source location using the included IR receivers/transmitters.
