4x2 HDMI 2.0 Matrix with 4K to 1080p downscaling and display control 18Gbps

VLMX-0402E

  • 4x2 HDMI 2.0 matrix switcher with two independently scalable outputs, routing four sources to two displays at 4K@60 4:4:4 (18Gbps)

  • Per-output downscaling to 1080p or HDBaseT mode (capped at 10.2Gbps), with distribution and switching operating modes

  • Automatic display power control via RS-232, CEC, or IR on signal loss or detection, plus a test-pattern mode

  • Dual de-embedded analog L/R and TosLink audio outputs (ARC decoded to TosLink), with control via front panel, RS-232, IR, and Web GUI over LAN

Product Description

The VLMX-0402E is an 18G HDMI matrix switcher featuring four HDMI inputs and two independently scalable HDMI outputs. Each input and output supports video resolutions up to 4K60 (4:4:4) with full HDMI 2.0 and HDCP 2.2 compliance.

Each output can be individually downscaled to 1080p, allowing compatibility with legacy displays or HDBaseT extension systems. The unit supports audio de-embedding for both outputs, providing analog L/R and optical TosLink audio outputs.

Designed for smart automation, the VLMX-0402E can automatically control connected display devices via RS232, CEC, or IR, either when the last input signal is lost or when a new signal is detected.

Flexible control options include front panel buttons, RS232, IR, and LAN. The switcher also offers two operational modes: distribution mode (where the same source is sent to both outputs) and switching mode (independent switching per output), making it a versatile solution for conference rooms, classrooms, and small-scale AV systems.

Key Features

  • HDMI 2.0, HDCP 2.2/1.4, and DVI 1.0 compliant

  • Four 18G HDMI 2.0 inputs, up to 4K@60 4:4:4

  • Two 18G HDMI 2.0 outputs, up to 4K@60 4:4:4

  • Both outputs individually scalable for 4K-to-1080p or HDBaseT mode

  • Automatic RS-232, CEC, and IR control of display power state

  • Two sets of de-embedded analog and TosLink audio outputs, one per output

  • ARC decoding to the TosLink audio outputs

  • Test-pattern mode for verifying output signal integrity

  • Built-in Web GUI for LAN control

  • Four control methods: front panel, RS-232, IR, and LAN
