Vertiv Avocent LV5520R-400 4K dual-head KVM extender

4K dual-head KVM extender receiver

The Vertiv Avocent LV5520R-400 is a 4K dual-head KVM extender receiver designed for remote console access. It supports video resolution up to 4096x2160 at 60Hz and transmits over CATx at 5Gb/s or fiber at 10Gb/s with ultra-low latency adaptive compression. The unit provides dual DisplayPort outputs, four USB 2.0 Type A ports, analog audio connections, an RJ12 serial port, and both RJ45 and SFP+ network interfaces. No drivers are required and it is compatible with all known operating systems.

Suited for dual-monitor operator stations needing

This receiver suits control rooms, broadcast studios, or secure facilities where a keyboard, dual monitors, mouse, and audio must sit far from the host computer. It handles two video heads, stereo audio, and USB peripherals over a single CATx or fiber link. Buyers who need only a single video head, require USB 3.0 speeds, or lack space for an external 12 VDC power supply should look at other solutions. The operating temperature range of 0°C to 40°C also limits use in harsh industrial environments.

Handles 4K60 dual-head with USB 2.0 and stereo audio

The extender comfortably handles dual-head 4K at 60Hz, two channels of 24-bit 96kHz PCM audio, and USB 2.0 full-speed devices such as keyboards, mice, and HID peripherals. Bandwidth heads-up occurs when high-throughput USB devices like mass storage or video capture are connected, as the link is limited to two USB channels. The 18W power supply and 0°C to 40°C operating range define the thermal and electrical headroom for continuous operation.
