Kramer VM-4DT: 1x4 4K60 4:2:0 Long-Reach HDBaseT Distribution Amplifier

The VM-4DT from Kramer is a robust, long-reach HDBaseT distribution amplifier designed to take a single HDMI source and deliver pristine, synchronized 4K60 4:2:0 video to four identical displays or receivers. Built for classroom, corporate, and post-production environments, this 1x4 extender distributor equalizes and reclocks the input signal, ensuring consistent picture quality and reliable performance across all outputs over standard CATx cabling. Perfect for multi-zone installations, control rooms, and digital signage deployments, the VM-4DT preserves the integrity of native HDBaseT signals while simplifying cabling and setup.

• 1x HDMI input to 4x HDBaseT outputs: turn a single source into four identical displays or sinks with synchronized video and audio across all outputs.
• Long-reach HDBaseT distribution: engineered for extended runs over CATx cables, enabling installations across large rooms, classrooms, or auditoria without compromising signal quality.
• Supports 4K60 video with 4:2:0 color sampling: delivers ultra‑high-definition content at smooth frame rates, ideal for digital signage, presentations, and immersive AV experiences.
• Signal integrity ensured by built‑in equalization and reclocking: maintains strong, artifact-free video across all outputs even with challenging cable runs.
• Compact, durable design for fixed installations: suitable for rack-mount or surface‑mount setups in professional AV environments, with straightforward integration into existing systems.

Technical Details of VM-4DT

• Product type: HDBaseT distribution amplifier (1 input, 4 outputs), designed to distribute native HDBaseT signals to multiple displays.
• Video support: 4K@60Hz with 4:2:0 color sampling across all HDBaseT outputs.
• HDBaseT compatibility: supports standard HDBaseT transmission with reliable, synchronized delivery to each output.
• Inputs/Outputs: 1 HDMI input; 4 HDBaseT outputs that carry video, audio, and control signals over CATx cabling.
• Cable distance capability: long-reach transmission over CAT5e/6/6a cabling, suitable for multi-room or large-area deployments.
• Signal processing: built‑in equalization and reclocking on each output to preserve image quality over extended cable lengths.
• Power: external power supply required (included with typical kits) for reliable operation.
• Enclosure and installation: compact, durable chassis designed for fixed installations; suitable for rack‑mount or surface mounting in professional AV setups.
• Control and compatibility: designed to integrate with standard HDMI sources and HDBaseT receivers/displays; supports pass-through of essential HDBaseT features across outputs.

How to install VM-4DT

• Power off all equipment before making any connections to prevent damage and ensure a clean startup.
• Connect the HDMI source to the VM-4DT input using a high‑speed HDMI cable rated for 4K60 video.
• Run four CATx cables from the VM-4DT HDBaseT outputs to the corresponding HDBaseT receivers or display endpoints located at the distant sites.
• Connect the external power supply to the VM-4DT and plug it into a suitable AC outlet to power the device.
• Power on the VM-4DT, the HDMI source, and all connected displays/receivers. If necessary, adjust display settings to ensure 4K60 resolution is active, and consider enabling any HDCP/compliance options supported by connected devices.

Frequently asked questions

• Q: What does the VM-4DT do? A: It is a 1x4 HDBaseT distribution amplifier that takes one HDMI input and distributes it to four identical HDBaseT outputs with signal equalization and reclocking for reliable, long-distance transmission.
• Q: How many outputs does VM-4DT provide? A: It provides four HDBaseT outputs, all delivering the same native input signal to multiple displays or receivers.
• Q: What resolutions are supported? A: The VM-4DT supports up to 4K at 60 Hz with 4:2:0 color sampling on all outputs.
• Q: How far can the signal travel? A: The device is designed for long-reach transmission over CATx cables, typically up to the distances supported by HDBaseT standards with CAT6a or better cabling, depending on cable quality and installation factors.
• Q: Is external power required? A: Yes, an external power supply is required and is included with the unit in most configurations.
• Q: Can I mix displays with different resolutions? A: All outputs carry the native HDBaseT signal from the single input; connected displays should support the same resolution to maintain uniform performance, though many displays will scale if needed.
