Description
The Galileo HDR4120 HDMI Extender represents a robust engineering solution for long-distance audio and video transmission, effectively bypassing the physical limitations of traditional HDMI cables. By utilizing standard CAT5e or CAT6 network cabling, this system delivers crisp 4K Ultra HD video at 30Hz up to 120 meters with minimal latency. Designed for both point-to-point and multi-receiver cascading setups, it integrates a local HDMI loop-out on the transmitter and infrared (IR) control pass-through, making it an indispensable tool for complex AV deployments.
This high-performance extender is engineered to meet the demands of diverse user groups seeking reliable long-range signal distribution:
- Home Theater Enthusiasts: Perfect for routing media players, gaming consoles like the PS4 or Xbox, and Blu-ray players from a central AV closet to distant displays without losing signal quality.
- Commercial AV Integrators: Ideal for setting up digital signage, conference rooms, and lecture halls where video sources must connect to remote projectors or commercial monitors.
- Security System Operators: Enables real-time monitoring by extending NVR or DVR video feeds to security desks located far from the server room.
- Event Production Teams: Simplifies temporary stage setups by using flexible, cost-effective Ethernet cables instead of rigid, expensive long-run HDMI cables.
- Educational Institutions: Facilitates classroom technology integration, allowing teachers to control media sources from the podium while projecting onto a screen across the room.
The technical architecture of the Galileo HDR4120 is built on precise, industry-standard specifications to ensure maximum compatibility and durability:
- Maximum Transmission Distance: Up to 120 meters (393 feet) using CAT5e or CAT6 Ethernet cables.
- Supported Resolutions: 4K (3840x2160) @ 30Hz, 1080p, 720p, 576p, 576i, 480p, 480i.
- HDMI Cable Compatibility: Supports AWG26 standard HDMI cables up to 15 meters for both input and output.
- Bandwidth and Speed: Maximum transmission bandwidth of 340MHz with a transfer rate of 3.4Gbps x3.
- Physical Interfaces (Transmitter): 1x HDMI Input, 1x HDMI Loop-Out, 1x RJ-45 Output, 1x 3.5mm IR-TX.
- Physical Interfaces (Receiver): 1x RJ-45 Input, 1x RJ-45 Output (for cascading), 1x HDMI Output, 1x 3.5mm IR-RX.
- Power Supply: Input AC 100-240V (50/60Hz), Output DC 5V/1A (center positive).
- Build Quality: Heavy-duty aluminum alloy housing measuring 107mm x 96mm x 29mm, weighing approximately 223g per unit.
In real-world applications, the Galileo HDR4120 excels in ease of deployment and operational stability. The plug-and-play design requires no software drivers or complex network configurations; simply connect the transmitter to your source, run the Ethernet cable, and connect the receiver to your display. The aluminum alloy chassis provides excellent heat dissipation, ensuring the internal chipsets remain cool during continuous 24/7 operation. The gold-plated HDMI connectors resist corrosion and maintain a tight, secure connection, preventing intermittent signal drops. Users will appreciate the local HDMI loop-out on the transmitter, which allows for local monitoring of the source feed without needing an external HDMI splitter.
Compared to standard active HDMI cables, which are bulky, expensive, and typically max out at 30 meters, the Galileo HDR4120 offers a highly scalable and cost-effective alternative. While basic HDMI over IP extenders only support simple point-to-point connections, the HDR4120 features a unique receiver-side RJ-45 output. This allows for daisy-chaining up to 10 receivers in a multi-drop configuration, with up to 100 meters of distance between each subsequent receiver. This cascading capability significantly reduces the amount of cabling required for multi-screen environments, making it far more versatile than traditional hub-and-spoke distribution systems.
To assist with planning and installation, here are answers to the most common technical queries regarding this system:
- Q: Does this product include the required Ethernet or HDMI cables?
- A: No, the package contains the transmitter, receiver, power adapters, and IR cables. High-quality CAT5e/CAT6 Ethernet cables and AWG26 HDMI cables must be purchased separately.
- Q: Can I control my source device from the remote display location?
- A: Yes, the built-in IR pass-through supports bidirectional infrared signals, allowing you to use your source device's remote control in front of the remote TV.
- Q: What is the maximum distance supported when cascading multiple receivers?
- A: The initial run from the transmitter to the first receiver supports up to 120 meters. Each subsequent cascaded receiver can be placed up to 100 meters from the previous unit, up to a maximum of 10 receivers.
- Q: Is this extender compatible with gaming consoles like the PS5 or Xbox Series X?
- A: Yes, it supports standard HDMI inputs from modern consoles, but output resolution will be capped at 4K at 30Hz or 1080p at 60Hz.
- Q: Does the system support HDCP content protection?
- A: Yes, the extender is designed to pass through standard HDCP-encrypted content, ensuring compatibility with Blu-ray players and streaming devices.
