Keystone module DELOCK stereo jack female 3.5 mm 4‑pin to stereo jack female 3.5 mm 4‑pin, black

DELOCK keystone module provides two stereo 3.5 mm female 4‑pin jacks in a single, compact housing designed for panel or keystone wall plate installations. The module creates a modular, accessible connection point for 4‑pole audio cables, allowing quick and tidy integration of headsets with microphone support or other CTIA-wired devices into fixed installations. Its black finish matches common faceplates and AV panels for a discreet appearance.

Advantages

This keystone module offers a standardized form factor for easy snap-in installation into keystone wall plates or panels, ensuring consistent alignment and secure retention. With two 3.5 mm female 4‑pole connectors, it supports both stereo audio and microphone signals through a single compact unit, reducing cable clutter and simplifying maintenance. The durable construction and black housing provide reliable mechanical stability and a neutral aesthetic for professional AV environments.

Suitable for

• Integrating headsets with microphone (CTIA wiring) into wall plates or panels
• Extending or relocating existing 3.5 mm 4‑pin audio connections in installations
• AV racks, conference rooms, classrooms, and multimedia stations requiring modular audio jacks
• Custom faceplate configurations where a compact dual 3.5 mm 4‑pin interface is needed

How to use

Insert the keystone module into a compatible keystone opening on a wall plate or AV panel until it snaps into place. Route the internal cabling or pigtails according to the installation layout and terminate them to the incoming 3.5 mm 4‑pole audio cables or breakout harness as required. Connect compatible 4‑pole plugs (such as CTIA headsets) to the front jacks for audio and microphone use. Verify alignment and secure the wall plate to the mounting surface to complete the installation.

Recommendations

Use this module with properly wired 4‑pole (TRRS/CTIA) cables and ensure cable shielding and routing follow best practice for AV installations. Avoid excessive mechanical strain on the connector by securing internal cables and using strain relief where possible.
