HDMI Coupler Female-to-Female Secomp S3220 – Standard HDMI Connector

Secomp S3220 is a standard HDMI female-to-female coupler that provides a straightforward inline connection to join two HDMI cables. Designed for use with standard HDMI connectors, this compact adapter maintains signal continuity for high-definition audio and video between displays, TVs, projectors and AV systems without active conversion. The S3220 is intended for situations where extending an HDMI run or linking two cables is required while keeping a simple, passive, and portable solution.

Advantages

The HDMI coupler offers a low-profile, passive connection that does not require power or configuration. Its matching female HDMI ports enable direct linking of two HDMI cables, preserving digital audio and video signals across the connection. The compact form factor makes it easy to install in tight spaces behind displays or inside cabinets, while its standard connector compatibility ensures broad interoperability with most HDMI cables and consumer AV equipment.

Suitable for

• Extending HDMI cable runs by joining two standard HDMI cables
• Connecting displays, TVs, projectors or AV receivers in home and office setups
• Temporary or portable AV arrangements where a quick inline connection is needed

When it may not be suitable

The passive female-to-female coupler is not suitable when an active signal booster, equalizer or repeater is required for very long cable runs beyond the HDMI specification limits. It will not convert between different connector types (for example HDMI to DisplayPort) or change HDMI versions or bandwidth capabilities of the connected cables and devices. For installations requiring signal conditioning, amplification or protocol conversion, an active device should be used instead.

Key specifications

• Connector type: female HDMI to female HDMI
• Function: passive inline coupler for audio and video signals
• Compatibility: standard HDMI connector systems and cables
• Form factor: compact, low-profile inline adapter
• Power: passive, no external power required

How to use

Ensure both HDMI cables to be joined have compatible standard HDMI male connectors. Insert one cable firmly into one side of the coupler and the second cable into the other side until both connectors seat fully. Check that connected devices are powered on and set to the correct input; the signal should pass through the coupler transparently. For best results, use high-quality HDMI cables and avoid adding multiple passive couplers in series, which can increase the chance of signal degradation.

What to consider before purchase

• Length and quality of HDMI cables: passive couplers do not amplify signals
• Required HDMI bandwidth: coupler does not change cable or device HDMI version
• Installation space: ensure physical clearance for the coupler and connected cables
• Signal needs: for long runs or challenging environments consider an active extender or repeater

Usage recommendations

Use the Secomp S3220 coupler for short to moderate cable extensions where a simple, passive connection is sufficient. Combine it with high-quality HDMI cables and avoid chaining multiple passive adapters. If you experience signal loss or intermittent connections, evaluate cable lengths and consider an active HDMI extender or powered repeater appropriate for your setup.
