About CAT HDMI & Audio Extenders
VigilLink's CAT HDMI and audio extender range covers three distinct use cases on a single Cat cable: full 4K@60Hz 4:4:4 HDMI 2.0 video extension with ARC and two-way IR at 70 meters (VLEX-CT070R-TR), combined HDMI video and TOSLINK digital audio extension at 70 meters (VLEX-CATH2070-TR), combined HDMI and TOSLINK audio to 150 meters (VLEX-HAACT150-TR), and pure digital audio extension at 300 meters (VLEX-ACT300-TR). These models are designed for installations where HDBaseT's full feature set is not required — shorter HDMI runs leveraging existing CAT cabling, and long-distance audio distribution to remote zone amplifiers without the cost of HDBaseT infrastructure. All VLEX-CAT audio and HDMI extenders ship with a 6-year VigilLink warranty.
Choosing the Right CAT HDMI & Audio Extender
HDMI 2.0 with ARC and IR — 70m (VLEX-CT070R-TR): Extends full 4K@60Hz 4:4:4 HDMI 2.0 at 18Gbps with ARC audio return and two-way IR over Cat5e/6 at 70 meters. Choose for presentation rooms and conference spaces where a shorter HDMI run over existing Cat cable is required and ARC return from the display is needed.
HDMI 2.0 with TOSLINK — 70m (VLEX-CATH2070-TR): Extends 4K@60Hz HDMI 2.0 at 18Gbps with simultaneous TOSLINK digital audio output at 70 meters. Choose when both HDMI video and a separate optical audio output are needed at the display location — for example, feeding a display and a DSP or audio zone amp from the same Cat cable.
Combined HDMI and TOSLINK Audio — 150m (VLEX-HAACT150-TR): Extends HDMI video and TOSLINK digital audio together over Cat cable to 150 meters. Choose for distributed AV systems where the display location and audio zone amplifier are farther from the source than the VLEX-CATH2070-TR's 70-meter limit allows.
Digital Audio Only — 300m (VLEX-ACT300-TR): Extends digital audio signal only over Cat cable to 300 meters — the longest audio extension range in the VLEX range. No HDMI video is carried. Choose when audio-only extension to a remote DSP, zone amplifier, or paging system is required and dedicated audio infrastructure over Cat cable is preferred over analog line runs.
Frequently Asked Questions
What is the difference between the VLEX-CT070R-TR and VLEX-CATH2070-TR?
Both extend 4K@60Hz HDMI 2.0 over Cat cable at 70 meters. The VLEX-CT070R-TR adds ARC audio return and two-way IR control. The VLEX-CATH2070-TR adds a TOSLINK optical audio output at the receiver, providing a separate digital audio feed alongside HDMI. Choose VLEX-CT070R-TR when ARC from the display is needed; choose VLEX-CATH2070-TR when a TOSLINK output for a local audio device is needed.
How far can the VLEX-ACT300-TR extend digital audio?
The VLEX-ACT300-TR extends digital audio over a single Cat cable to a maximum of 300 meters. This makes it suitable for large-venue and campus audio distribution where analog line runs would suffer noise and signal loss over equivalent distances.
Does the VLEX-HAACT150-TR carry both HDMI and audio on the same Cat cable?
Yes. The VLEX-HAACT150-TR extends HDMI video and TOSLINK digital audio simultaneously over a single Cat cable to 150 meters, providing both video and audio to the remote location without a separate audio cable or second Cat run.
Do CAT extenders in this family support HDCP 2.3?
Yes. HDMI 2.0 models (VLEX-CT070R-TR, VLEX-CATH2070-TR, VLEX-HAACT150-TR) maintain HDCP 2.3 compliance throughout the extension link, supporting protected 4K content from streaming devices, Blu-ray players, and HDCP-encrypted sources.
What Cat cable type is required for these extenders?
Cat5e or Cat6 is sufficient for all models in this family. Cat6 is recommended for runs approaching the maximum rated distance to ensure signal margin. Shielded cable (STP) is advisable in electrically noisy environments.
