SOtM iSO-CAT6

SOtM iSO-CAT6 Ethernet LAN Isolator & Noise Filter

Cleaner Network Connections. A More Refined Digital Audio Environment.

The SOtM iSO-CAT6 Ethernet Isolator is a specialist passive LAN signal filter developed for high-end digital audio systems.

Designed to address unwanted electrical interference associated with Ethernet connections, the iSO-CAT6 combines a high-quality isolation transformer, fully shielded modular connections and SOtM’s audio-oriented approach to network signal management.

Its purpose is to provide additional electrical isolation between compatible network devices, helping to manage unwanted noise that may be present along the network connection.

Available in Standard and Special Edition configurations, the iSO-CAT6 can be integrated into network audio systems using compatible Ethernet streamers, servers, switches and other digital components.

Why Network Isolation Matters in Digital Audio

Modern music systems frequently bring together several network-connected components, including routers, switches, streamers, servers and network-attached storage devices.

Although Ethernet provides robust digital data transmission, the electrical environment surrounding these devices can be complex.

Computer hardware, switching power supplies and other electronics may introduce unwanted electrical disturbances into the system.

Some of this interference may interact with sensitive downstream circuitry, depending on the design and isolation of the connected devices.

The SOtM iSO-CAT6 is designed to address this aspect of network audio by providing an additional isolation stage within a compatible Ethernet connection.

It is important to distinguish electrical noise management from digital data integrity. The iSO-CAT6 does not increase the resolution of music files or change the audio data being transmitted.

High-Quality LAN Signal Isolation

At the heart of the SOtM iSO-CAT6 is a high-quality isolation transformer, combined with fully shielded modular network connections.

SOtM specifies an isolation test rating of 1,500 Vrms with the stated test conditions of 0.5mA for 60 seconds.

The unit supports CAT6 network connections and is intended for insertion into a compatible Ethernet signal path.

The additional isolation stage is designed to help manage unwanted electrical noise while maintaining the required network signal connection.

The published isolation figure is a component specification and should not be interpreted as approval to use the product as a protective electrical safety barrier.

Passive Operation Without an External Power Supply

One of the practical advantages of the iSO-CAT6 is its passive design.

The unit requires no external DC power supply, AC mains cable or additional power outlet.

This allows it to be installed without adding another powered device to the audio rack.

The compact configuration is suitable for installations where simplicity and convenient placement are important.

Integrating the iSO-CAT6 into a Network Audio System

The iSO-CAT6 is designed to sit between compatible Ethernet-connected devices.

Typical system applications include the network connection to a music streamer or dedicated digital audio transport.

For example, an installation may involve a router or network switch connected through the iSO-CAT6 to a compatible streamer.

SOtM recommends switching off the connected equipment before making or changing connections.

The manufacturer’s operating instructions should be followed for the correct connection orientation and configuration.

Because the device incorporates transformer isolation, its suitability for Power over Ethernet (PoE) installations must not be assumed. Check compatibility before connecting PoE-powered equipment.

SOtM iSO-CAT6 Special Edition

The SOtM iSO-CAT6 Special Edition combines the standard isolation unit with three specially selected short CAT7 network cables.

The Special Edition package includes:

• 1 × SOtM iSO-CAT6 LAN isolation unit
• 1 × Black CAT7 Ethernet cable, 50cm
• 1 × Grey CAT7 Ethernet cable, 50cm
• 1 × Dark Grey CAT7 Ethernet cable, 50cm

These cables have been selected by SOtM for their different subjective sound characteristics when used in compatible audio systems.

The concept allows listeners to experiment with different cable combinations and select the presentation they prefer.

Three Distinct Cable Options

SOtM describes the three supplied Special Edition cables as follows:

These descriptions represent the manufacturer’s subjective listening observations. The cables do not modify the digital music data or its resolution.

The actual result depends on the connected equipment and listening system.

Standard vs Special Edition

The Standard version is the appropriate choice for listeners who want to integrate SOtM’s LAN isolation technology into an existing network system using their current compatible Ethernet cables.

The Special Edition adds three 50cm CAT7 cables intended to provide additional system-matching and listening options.

The fundamental isolation device remains the central component of both versions.

For customers building a complete SOtM network audio system, the Special Edition offers a convenient package for experimenting with different cable combinations.

Combining iSO-CAT6 with SOtM Network Cables

SOtM recommends combining the iSO-CAT6 with selected cables from its specialised Ethernet range.

For example, the
SOtM dCBL-CAT7e Ethernet Cable
offers shielded Category 7 construction, a special noise-filtering design and a wide range of available lengths.

Combining suitable network cabling with the iSO-CAT6 allows a system to be developed around the manufacturer’s broader approach to network audio connectivity.

A Companion for the SOtM sMS-500

The
SOtM sMS-500 Network Streamer
is a next-generation digital audio transport using SOtM’s Eunhasu operating environment.

Its wired Ethernet interface makes it a relevant candidate for a network audio system incorporating an iSO-CAT6 isolator.

As with all network accessories, the final configuration should be assessed for correct operation and suitability with the connected equipment.

Listening Experience and System Matching

SOtM developed the iSO-CAT6 with the aim of reducing unwanted electrical interference that may affect sensitive audio systems.

The manufacturer associates its noise-management approach with improvements in perceived clarity, instrumental separation and musical expression.

Independent listening reports have also described differences in spatial presentation, timbre and detail in particular systems.

These impressions are subjective and should not be interpreted as universal results.

The degree to which additional network isolation can influence playback depends on the existing isolation, grounding and circuitry of the connected equipment.
