SilentPower has unveiled new multiport variants of its acclaimed LAN iSilencer and LAN iPurifier Pro. Designed for the demands of the pro AV and custom installation markets, these next-generation solutions deliver the same noise suppression, electrical isolation and data protection, only now in a compact, 1U rack-mountable format ideal for professional system builds.
The four new variants are the LAN iSilencer 4 [4 in / 4 out], LAN iSilencer 8 [8 in / 8 out], LAN iSilencer 12 [12 in /12 out] and the LAN iPurifier Pro 4 [4 in / 4 out].
In professional or custom environments, network reliability and signal integrity are paramount. Yet, off-the-shelf network devices are typically designed with a singular focus on data throughput, not the nuanced demands of AV performance.
This results in a common but often invisible problem: interference. Whether introduced by switching regulators, poor PCB layout, or inadequate shielding, noise can propagate unchecked through Ethernet cabling – especially in systems where multiple devices share a network.
Rather than filtering noise, the network becomes a carrier for it, amplifying the issue system-wide. When interference is transmitted through Ethernet cabling alongside digital data, it impacts timing at the conversion stage, compromising the precision required for accurate audio/video conversion – particularly noticeable in high-resolution or time-sensitive applications.
In larger-scale installs, proximity to AC power lines can introduce DC bias voltages, further destabilising the LAN signal. In severe cases, communication between network endpoints can fail entirely.
These are not edge cases – they are endemic to modern AV networks that lack purpose-built signal conditioning. SilentPower’s latest range of multiport LAN solutions directly address these challenges, delivering robust electrical isolation, advanced interference suppression, and optimised signal performance in demanding deployments.
SilentPower’s LAN iSilencer is a passive data line isolator designed specifically for the rigours of professional-grade environments. Housed within a fully shielded RJ45 plug and socket with dedicated grounding, it employs transformer-based architecture to provide galvanic isolation between network infrastructure and endpoint devices. This eliminates ground-loop induced noise and common-mode interference, ensuring clean, stable transmission. Beyond electrical isolation, the iSilencer incorporates passive RF filtering to reduce the impact of high-frequency RFI.
A key benefit of the transformer-based design is the elimination of DC bias – a common cause of LAN instability, especially in long-run cabling near AC power infrastructure. The LAN iSilencer outputs a balanced signal with no voltage offset, resolving communication issues even in electrically noisy environments such as machine rooms, server racks, data closets and behind AV walls in smart homes or commercial buildings.
To support larger-scale installations, SilentPower now offers multiport rack-mountable variants of the LAN iSilencer in configurations of four, eight, or 12 isolated ports. Each port functions independently but is conveniently housed in a compact 1U chassis, compatible with SilentPower’s Rack Mount Kit. This consolidated design simplifies deployment across enterprise AV racks, conference facilities, post-production studios, hospitality environments, and high-end residential systems – wherever clean, stable LAN connectivity is critical.
All LAN iSilencer variants are fully Gigabit Ethernet (GbE) compatible, making them easy to integrate into both legacy and modern high-speed network infrastructure.
In critical AV environments, even minor electrical noise or timing inconsistencies can compromise system performance. Designed for the most demanding applications, the LAN iPurifier Pro delivers optical galvanic isolation and advanced signal conditioning.
Unlike transformer-based designs, the LAN iPurifier Pro converts incoming Ethernet data into light, transmitting it across an optical barrier before reconversion. This process eliminates all direct electrical pathways between input and output, effectively blocking common-mode noise, stray voltages, and parasitic coupling that can pass through conventional isolation methods.
Once isolated, the LAN iPurifier Pro reconstructs the digital signal using active circuitry. This bit-perfect reconstruction mitigates jitter and restores timing accuracy, ensuring optimal performance for critical components such as streamers, network bridges, digital processors, and audio servers.
An integrated ultra-low-noise DC-DC power supply ensures clean internal operation, while support for external low-noise linear power supplies enables system-wide optimisation. As such, the LAN iPurifier Pro is particularly well suited to professional AV installations, mastering suites, high-end listening rooms, and other noise-sensitive commercial applications.
The LAN iPurifier Pro 4 integrates four independent LAN iPurifier Pro units into a single 1U chassis. Designed for seamless installation using SilentPower’s Rack Mount Kit and fully GbE compatible, the LAN iPurifier Pro 4 delivers high-performance optical isolation and signal regeneration in a format tailored for mission-critical networks.
The LAN Silencer 4/8/12 and LAN iPurifier Pro 4 are available to purchase at silentpower.tech and authorised dealers.
