TV wall socket SCHNEIDERE Sedna SDD111474 pass-through 7 dB white

SCHNEIDERE Sedna SDD111474 pass-through TV wall socket in white is a coaxial outlet designed for in-wall installation and signal distribution in residential and commercial environments. The socket provides a through connection with 7 dB attenuation, allowing continuity of the RF signal while lowering signal level where required. Its neutral white finish integrates with standard wall plates and interior décors, and the modular form factor is compatible with common mounting boxes and faceplates.

Advantages

The pass-through design maintains a continuous coaxial path for linking several outlets or devices without interrupting the feed. Built-in 7 dB attenuation helps prevent signal overload and adjusts signal levels for downstream equipment. The white finish offers a discreet visual appearance, while the compact wall-mount format simplifies installation in single-gang or modular frames. The socket is suitable for a variety of coaxial TV cabling setups and supports easy replacement or extension of existing outlets.

Suitable for

• Connecting TV set-top boxes, televisions and recorders within living rooms and bedrooms
• Extending signal lines in apartments, houses and office spaces
• Linking multiple wall outlets in cascade installations where signal attenuation is required
• Upgrading or replacing existing coaxial wall outlets in residential or commercial projects

Key specifications

• Function: pass-through coaxial TV wall socket with attenuation
• Attenuation: 7 dB
• Color: white
• Mounting: in-wall wallplate/module compatible
• Connector type: coaxial female (IEC-style) for TV/RF connections

How to use

Install the socket into an appropriate in-wall mounting box or compatible faceplate following local electrical and installation codes. Connect the incoming coaxial feed to the socket input and attach the downstream coaxial cable to the output to create a continuous pass-through path. Ensure connectors are tightened to provide reliable RF contact and inspect the cable shielding and connector condition for proper signal transmission. After installation, test television reception and adjust downstream amplifiers or splitters if necessary to account for the 7 dB attenuation.

Usage recommendations

Use the 7 dB attenuation socket where a reduced signal level is needed to prevent overload of tuners or amplifiers, or when cascading multiple outlets. Avoid using the pass-through without proper shielding or with damaged coaxial connectors to maintain signal quality. For complex signal distribution, verify overall system level with appropriate measuring equipment or consult a professional installer.
