CNV-LKV683MATRIX-4RX

Overview

Lenkeng LKV683Matrix-4.0 4K 30Hz 120m HDMI over IP Matrix Receiver is a professional-grade video distribution solution designed for scalable AV installations that require reliable long-distance transmission and flexible signal switching. Built on HDbitT technology, this receiver-only unit supports high-definition HDMI signal delivery over IP networks, making it suitable for commercial environments, control rooms, digital signage, and multi-display setups.

Description

This receiver unit is engineered to extend and distribute HDMI signals over IP infrastructure with support for up to 4K resolution at 30Hz. It enables stable video and audio transmission over distances of up to 120m while maintaining signal integrity. With IR passback support, users can remotely control source devices from the display end. The system is designed for integration with IGMP network switches, allowing flexible matrix configurations for large-scale deployments. It supports HDCP-compliant HDMI 1.4 signals and delivers consistent performance across a wide range of resolutions and AV environments.

Features

IP-Based HDMI Matrix Distribution for Scalable Systems
The Lenkeng LKV683Matrix-4.0 receiver is part of an advanced IP matrix system that allows video sources to be distributed and switched across multiple endpoints. It supports integration of up to 100 source signals within a networked matrix environment, enabling dynamic routing to virtually unlimited outputs depending on network configuration.

Part number / SKU: CNV-LKV683MATRIX-4RX

This makes it suitable for installations requiring centralized control of multiple HDMI sources, such as corporate AV systems, retail displays, and large venue signage networks.

Stable 4K Transmission Over Extended Distances
Designed for long-range performance, this receiver supports HDMI signal transmission up to 120 meters over standard network infrastructure. It delivers 4K at 24/25/30Hz along with full HD and lower resolutions for compatibility across mixed display environments.

Supported resolutions include:

• 480i and 480p at 60Hz
• 576i and 576p at 50Hz
• 720p at 50/60Hz
• 1080i and 1080p at 50/60Hz
• 4K at 24/25/30Hz

Audio is supported in PCM format, ensuring clear and synchronized playback across connected devices.

Control Flexibility and IR Passback Support
The system includes IR passback functionality operating within 20 to 60KHz, allowing users to control source devices remotely from the receiver location. This improves operational flexibility in installations where source equipment is located in secure or centralized racks.

Remote control functionality is supported, enabling easier switching and management of connected devices within the matrix network.

Network Performance and HDbitT Architecture
Built on HDbitT transmission technology, the system uses standard IP networking with a bandwidth requirement of approximately 18Mbps. It is compatible with IGMP-managed switches, enabling efficient multicast distribution across complex AV networks without unnecessary network congestion.
