RF bleed is a persistent issue in venues near broadcast transmitters, wireless-dense environments, and urban install sites where stray frequencies couple onto balanced lines and appear as audible noise or interference at the console.\u003c\/p\u003e\u003cp\u003eThe RFBLOX drops into any balanced XLR signal path without tools or configuration, making it practical for front-of-house troubleshooting, installed sound rack patching, or stage box wiring where RF noise is intermittent or hard to trace. Its compact aluminum shell withstands the physical demands of touring and fixed install use without adding bulk to a cable run or rack panel.\u003c\/p\u003e\u003cp\u003eWhere passive DI boxes or grounding lifts fail to resolve interference, an RF choke addresses the problem at the frequency level, making the RFBLOX a targeted and cost-effective diagnostic and corrective tool for engineers who need a reliable fix without signal-path compromise.\u003c\/p\u003e","brand":"RapcoHorizon Int RHC Holding","offers":[{"title":"Default Title","offer_id":52446604951736,"sku":"62900","price":52.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/62900_RAPHOR-RFBLOX_ALT01.jpg?v=1783628724","url":"https:\/\/soundpro.com\/products\/rapcohorizon-rfblox","provider":"SoundPro","version":"1.0","type":"link"}
