{"product_id":"alfatron-electronics-alf-tpa33","title":"Alfatron ALF-TPA33 Audio Over CAT Extender Set","description":"\u003cp\u003eThe Alfatron Electronics ALF-TPA33 is a complete audio extension solution designed for AV integrators and installers who need to distribute high-quality audio across long CAT6 runs without running dedicated audio cabling. The set includes both a transmitter and receiver, making it a plug-and-play deployment for fixed install environments including conference rooms, houses of worship, digital signage networks, and multi-zone audio distribution systems.\u003c\/p\u003e\u003cp\u003eThree switchable inputs on the transmitter cover TOSLINK optical, coaxial digital, and stereo RCA analog sources, while the receiver mirrors those same three output types simultaneously. This symmetry means a single cable run can serve a destination requiring any audio format without adapters or additional conversion hardware. Digital formats including PCM, Dolby, and DTS pass through intact, with channel support from 2.0 up to 7.1 for optical and coaxial paths.\u003c\/p\u003e\u003cp\u003eWhere many competing extenders require a local power supply at both ends, the ALF-TPA33 uses Power over CAT Cable technology to feed the transmitter directly from the receiver's 12VDC supply. This reduces installation complexity at the source end, a practical advantage in ceiling, wall-mount, or rack-adjacent deployments where outlet access is limited. Stereo analog extension reaches up to 170 meters, while TOSLINK and coaxial digital signals carry up to 290 meters, making this kit viable for large-venue and campus-scale installs on standard CAT6 infrastructure.\u003c\/p\u003e","brand":"Alfatron Electronics, Inc.","offers":[{"title":"Default Title","offer_id":52449621147832,"sku":"111921","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/111921_Alfatron-Electronics-ALF-TPA33-Audio-Over-CAT-Extender-Set_ALT01sqr.jpg?v=1788970554","url":"https:\/\/soundpro.com\/products\/alfatron-electronics-alf-tpa33","provider":"SoundPro","version":"1.0","type":"link"}
