SilentPower Ethernet signal conditioner

The LAN iSilencer 4/8/12 is a multi-port network conditioner designed to clean and stabilize Ethernet connections across your system. Built with galvanic isolation, RF noise filtering, and surge protection, it addresses interference at the network level (where noise often enters unnoticed) and delivers a more stable signal to connected devices. Available in 4, 8, and 12-port configurations, it scales with systems ranging from simple desktop rigs to full rack installations. 

Galvanic isolation that breaks noise at the source

Each input/output pair is electrically isolated using a transformer that delivers up to 1500Vrms isolation. This prevents ground loops and stops unwanted electrical noise from traveling between devices. In practice, this means your network components operate independently rather than sharing contamination through the Ethernet line. 

Passive RF filtering for cleaner data transmission

High-frequency interference can ride along Ethernet cables and affect downstream components. The LAN iSilencer uses passive filtration to remove RF noise without adding active circuitry. This reduces interference before it reaches sensitive equipment such as streamers, DACs, and servers.

DC bias removal for signal integrity

REBalance technology removes DC offset that can accumulate in network connections. By correcting this imbalance, the device maintains proper signal conditions across all port, and helps connected devices operate within their intended electrical range. 

Surge protection built into every connection

Transient Voltage Suppression protects against voltage spikes up to 400W peak. This safeguards your network gear from sudden electrical events without requiring external protection devices. 

Gigabit-ready performance for modern networks

The LAN iSilencer supports 1000BASE-T Gigabit Ethernet along with 100Mbps and 10Mbps standards. It maintains full network speed while conditioning the signal, so performance is preserved even in demanding setups. 

Multi-port design that scales with your system

Available in 4, 8, or 12-port configurations, the LAN iSilencer adapts to different system sizes. Each port pair is independently isolated, allowing multiple devices to benefit from the same level of protection and noise reduction.
