Calrad 42-119 3.5mm Male to Dual Stereo Female Adapter

Product Description

The CALRAD 42-119 is a 4-conductor 3.5mm male to dual 3.5mm stereo female adapter designed for splitting or routing audio signals from a single source to two outputs. The male plug features a 4-conductor (TRRS) configuration, allowing it to carry both stereo audio channels through one connection. This type of adapter is commonly used in AV installation, portable audio setups, and low-voltage signal distribution work. Installers and technicians use it to split a combined headset jack into two separate stereo female connections.

This adapter fits residential and light commercial AV applications where a single 3.5mm jack needs to feed two devices simultaneously, such as splitting audio to two sets of headphones or routing signal to separate input channels. It is also useful in situations where a TRRS source jack needs to be broken out into discrete stereo outputs. No power is required for operation.

Key Features

• 4-conductor (TRRS) 3.5mm male plug for compatibility with combined audio jacks
• Splits to two 3.5mm stereo female outputs for dual-device connectivity
• Passive design requires no external power source
• Compact form factor for use in tight AV panels or portable rigs

Compatibility

Designed as a standard passive adapter for use with 3.5mm TRRS audio sources and stereo 3.5mm female input devices in residential and light commercial AV applications.

Installation Notes

This adapter is installed by AV technicians or low-voltage specialists and requires no tools beyond hand-tightening the connector. Ensure the source jack supports a 4-conductor TRRS configuration before use, as a standard 3-conductor TRS plug will not carry the full signal split. No power shutdown is required prior to installation, but disconnect source audio before plugging in to avoid signal pops or transient noise on connected devices.
