{"product_id":"hzproject-hz-lan-isolator","title":"HzProject Hz LAN Isolator","description":"\u003ch2\u003eHz LAN Isolator — Network-Audio Noise Rejection\u003c\/h2\u003e\n\u003cp\u003eA network-audio noise-rejection device for the streaming chain — galvanic isolation between your network and your DAC or music server, in a hand-machined aluminum body the size of a deck of cards.\u003c\/p\u003e\n\u003cp\u003eStreaming audio sounds as good as the network feeding it. Routers, switches, and Wi-Fi extenders inject electrical noise and high-frequency interference into the Ethernet line; that noise rides downstream into the DAC's clock and analog stages, where it shows up as a small but real loss of refinement. The Hz LAN Isolator is HzProject's purpose-built answer: a passive in-line device that galvanically isolates the upstream network from the downstream music component, blocking the electrical path noise travels on while passing the music data losslessly.\u003c\/p\u003e\n\u003cp\u003eThe construction is what you'd expect from HzProject. The body is milled from two solid pieces of non-magnetic, high-grade aluminum — small, dense, machined cleanly. Inside sit three filtering cells: two complementary cells positioned upstream and downstream of a central 2.5G Base-T isolation transformer, with a shielded modular jack carrying gold-plated contacts. No external power supply is required; the device draws what little it needs from the Ethernet signal itself, in line with Power-over-Ethernet conventions. A 30-centimeter shielded CAT 6 cable is included in the box for the immediate downstream connection.\u003c\/p\u003e\n\u003cp\u003ePlace it between your network switch and your music server, or between your Wi-Fi extender and your DAC. It pairs naturally with the HzCORE music server — the same engineering vocabulary, the same component-level isolation discipline — but the LAN Isolator is system-agnostic: any Ethernet-connected DAC, streamer, or Roon endpoint benefits from cleaner network audio at the input.
