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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-conductor (TRRS) 3.5mm male plug for compatibility with combined audio jacks\u003c\/li\u003e\n\u003cli\u003eSplits to two 3.5mm stereo female outputs for dual-device connectivity\u003c\/li\u003e\n\u003cli\u003ePassive design requires no external power source\u003c\/li\u003e\n\u003cli\u003eCompact form factor for use in tight AV panels or portable rigs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: 3.5mm 4-conductor (TRRS) male to dual 3.5mm stereo female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Count\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CALRAD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42-119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CALRAD","offers":[{"title":"Default Title","offer_id":51524896719154,"sku":"42-119","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7e8ac98997462f18e1b20449301b5fe.jpg?v=1785460983","url":"https:\/\/voomisupply.com\/products\/calrad-42-119-3-5mm-male-to-dual-stereo-female-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
