Option 1 TX and 3 RX kit

  • One transmitter drives seven receivers for multi-room video distribution
  • Extends 1080P HDMI up to 120 metres over a single Cat5/Cat6/Cat7 cable
  • Runs 24 hours a day without interruption for continuous operation
  • Functions as both extender and splitter from one source
  • Incompatible with earlier 2.0 and 3.0 hardware versions

Kit Contents

This kit provides one transmitter and seven receivers for distributing a single HDMI source to multiple displays. It is intended for installers and AV professionals who need point-to-multipoint signal distribution over structured cabling. The transmitter accepts an HDMI input and sends the signal to all connected receivers simultaneously. Each receiver outputs the signal to a local display device.

Version Compatibility

The LKV373A V4.0 hardware is not compatible with LKV373 V2.0 or LKV373A V3.0 units, so existing installations using those versions cannot be expanded with this kit. Buyers replacing a failed V4.0 transmitter or receiver can integrate these units directly. The upgrade is worth it when a V4.0 system requires additional endpoints or a complete spare kit for redundancy. Mixed-version deployments will not function.

Sustained Operation

The extender supports continuous 7x24 operation at 1080P@60Hz resolution over Cat5, Cat5e, or Cat6 cable runs up to 120 metres. Signal integrity is maintained across the full distance without intermediate repeaters. The units are designed for constant use in commercial environments such as digital signage, control rooms, or distributed AV systems where downtime is not acceptable. Heat dissipation is handled passively during extended duty cycles.
