Engineered with dual shielded RJ45 ports and an unpowered passive architecture, the unit achieves 1500 Vrms of galvanic isolation across Cat5 to Cat8 network cabling. This inline suppression mitigates radio frequency interference and common-mode noise before data reaches sensitive network switches or music streamers.\u003c\/p\u003e\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\u003cp\u003eIn digital streaming systems, electrical noise transmitted through domestic network infrastructure frequently compromises the baseline noise floor. The Silent Angel LF SP counters this issue directly at the Ethernet interface, operating entirely without active internal power circuitry that could generate parasitic switching interference. Introducing this passive filter into the physical data path yields an audible reduction in digital haze, allowing subtle spatial cues and instrument decay to resolve with greater precision. It serves as an uncoloured, permanent inline measure for listeners dedicated to protecting digital signal integrity.\u003c\/p\u003e\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Gigabit 2.5GbE Bandwidth:\u003c\/strong\u003e Passes Ethernet signals up to 2500 Mbps with minimal insertion loss to maintain full throughput across modern high-speed streaming infrastructure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1500 Vrms Galvanic Isolation:\u003c\/strong\u003e Breaks conductive ground loops and blocks stray currents between network components without introducing signal attenuation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassive Noise Suppression:\u003c\/strong\u003e Operates without an external power source to eliminate electromagnetic and radio frequency interference without introducing power supply hash.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer for Silent Angel:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer for Silent Angel, providing authentic factory warranty coverage and technical assistance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand \/ Model:\u003c\/strong\u003e Silent Angel LF SP (LF-SP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Passive 2.5GbE Hi-Fi LAN Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork Speed:\u003c\/strong\u003e 10 \/ 100 \/ 1000 \/ 2500 Mbps (Auto-negotiating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI\/O Connectors:\u003c\/strong\u003e 2 x RJ45 female (shielded modular interface)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Compatibility:\u003c\/strong\u003e Cat5, Cat5e, Cat6, Cat6a, Cat7, Cat8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Performance:\u003c\/strong\u003e 1500 Vrms withstand voltage (leakage current ≤ 0.5 mA, sustained for 60 seconds)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsertion Loss:\u003c\/strong\u003e 1–50 MHz ≤ -0.5 dB; 50–125 MHz ≤ -1.0 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Requirements:\u003c\/strong\u003e None (fully passive architecture)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0 °C to +85 °C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x D x H):\u003c\/strong\u003e 108 mm x 32 mm x 26 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes the Silent Angel LF SP require an external power adapter?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. The Silent Angel LF SP operates entirely passively, requiring no DC or AC power supply.
