Gold‑Plated Connectors – Why They Matter

The connectors on the Goobay 31889 are gold‑plated, a feature that offers several advantages:

• Corrosion Resistance: Gold does not oxidize, ensuring long‑term reliability even in humid environments.
• Low Contact Resistance: Maintains signal integrity over time, reducing the likelihood of dropouts or degraded picture quality.
• Aesthetic Appeal: The subtle gold finish adds a premium look without compromising functionality.

Integrated Ethernet – Dual‑Purpose Connectivity

The cable’s built‑in Ethernet channel allows you to transmit network data alongside video and audio signals. This feature is particularly useful for:

• HDMI‑CEC (Consumer Electronics Control): Enables remote control of multiple devices via a single HDMI connection.
• Audio Return Channel (ARC) & eARC: Facilitates high‑quality audio return from the TV to an AV receiver or soundbar.
• Network Streaming: Supports streaming services that require a wired internet connection, such as Plex or local media servers.

Durability and Flexibility – The 6.5 mm Core Advantage

The cable’s core diameter of 6.5 mm strikes an optimal balance between flexibility and structural integrity:

• Flexibility: Allows easy routing around furniture or along walls without kinking.
• Strength: A thicker core resists abrasion and accidental pulls, extending the cable’s lifespan.
• Heat Dissipation: The larger diameter aids in dissipating heat generated during high‑bandwidth operation.

Installation Tips for Optimal Performance

1. Avoid Sharp Bends: Keep bends at a radius of at least 6 cm to prevent internal damage.
2. Separate from Power Cables: Run the HDMI cable parallel but not directly adjacent to power cords to minimize EMI.
3. Secure Connections: Ensure that both ends are fully seated in their respective ports; a loose connection can cause intermittent signal loss.
4. Use Cable Management: Employ Velcro ties or cable sleeves for neat routing, especially in tight spaces.

Maintenance and Care Guidelines

To preserve the cable’s performance over time, follow these simple care instructions:

1. Store Flat or Rolled: Avoid storing in tight coils that could kink the internal wires.
2. Clean Connectors Sparingly: Use a dry microfiber cloth; excessive cleaning can damage the gold plating.
3. Check for Wear Periodically: Inspect the cable ends and connectors for signs of abrasion or corrosion.
