{"product_id":"rapcohorizon-isoblox","title":"RapcoHorizon ISOBLOX Inline XLR Signal Isolation Box","description":"\u003cp\u003eThe RapcoHorizon ISOBLOX is a passive inline isolation device built for audio engineers who need reliable ground loop elimination on balanced XLR signal paths. With a 1-to-1 transformer and matched 600 ohm source and load impedance, it inserts transparently into any balanced line without introducing level shift or impedance mismatch — a critical requirement when interfacing consoles, outboard gear, broadcast feeds, or installed audio zones that share different ground references.\u003c\/p\u003e\u003cp\u003eLive sound engineers use the ISOBLOX between stage boxes and FOH racks to kill hum introduced by long cable runs or shared power distribution. Install integrators rely on it when tying AV systems into building infrastructure where ground potential differences are unavoidable. The XLR female input and XLR male output allow it to drop into any standard mic or line cable path without adapters, keeping the signal chain clean and the troubleshooting simple.\u003c\/p\u003e\u003cp\u003eUnlike software-side fixes or active DI workarounds, this hardware solution requires no power and adds no latency, making it a reliable first-response tool for persistent noise issues in touring, broadcast, and fixed-install environments where uptime is non-negotiable.\u003c\/p\u003e","brand":"Rapco-Horizon","offers":[{"title":"Default Title","offer_id":51443416236216,"sku":"57162","price":57.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/57162_RapcoHorizon-ISOBLOX-Inline-Isolation-Direct-Box.jpg?v=1768240479","url":"https:\/\/soundpro.com\/products\/rapcohorizon-isoblox","provider":"SoundPro","version":"1.0","type":"link"}
