The Matrix Audio SS-1 is an audio grade network switch. If you are new to high-end audio, think of it as a special version of the little box that manages your internet connections at home, except this one is built and tuned specifically to feed a music streamer as cleanly as possible.
A regular network switch just moves data from one device to another. It does not care whether that data is going to your laptop, your smart TV, or your music system. The SS-1 does move data too, but it is designed with one job in mind: to hand off a quiet, stable network signal to the device that turns that data into music. In plain terms, it sits between your home network and your streamer, cleaning things up along the way.
Why would anyone put a switch in a music system?
Because the network feeding your streamer can carry electrical noise, and reducing that noise can make your system sound cleaner and more relaxed. This surprises a lot of newcomers. It is easy to assume that digital audio is just ones and zeros, so it either works or it does not. The data itself does arrive intact, but the network cable and everyday networking gear also carry small amounts of electrical noise and timing jitter along with it.
That noise can ride into your streamer and, from there, affect the sensitive analog and digital circuits that ultimately produce sound. The SS-1 is built to lower that noise before it ever reaches your streamer. That is the whole idea behind an audio grade switch.
Where the SS-1 Fits in Your System
Where does the SS-1 go in the chain?
The SS-1 goes upstream of your network streamer or transport, meaning it sits earlier in the signal path than your streamer. A simple way to picture it: your internet router or home network connects to the SS-1, and the SS-1 then connects to your streamer.
So the flow looks like this. Your router or main network feeds the SS-1. The SS-1 does its cleanup and isolation work. Then a single clean connection runs from the SS-1 to your streamer. Everything downstream of the streamer, such as your DAC, amplifier, and speakers, stays exactly as it was. You are simply improving the quality of the network signal arriving at the front door of your streaming setup.
What does "network noise reduction and isolation" actually do for me day to day?
It gives your streamer a calmer, more stable signal to work with, which listeners often describe as a cleaner and more natural sound. Day to day, you do not press any buttons or fiddle with settings. Once the SS-1 is in place, it quietly does its job every time you play music. The benefit is not about faster streaming or fewer dropouts in the way you might expect from a normal network upgrade. It is about lowering the electrical grime that can subtly horn in on the music.
The Connections Explained
What are the two 100Mbps RJ45 ports for?
The SS-1 has two 100Mbps RJ45 ports, which are standard Ethernet sockets running at 100 megabits per second. RJ45 is simply the name for the common rectangular network connector that clicks into place, the same shape you already use for wired internet.
The 100Mbps speed is intentionally modest, and that is a good thing here. Audio streaming needs very little bandwidth, so a slower, lower noise port can actually be an advantage for feeding a streamer. You would typically use one of these ports for the connection heading to your streamer, where clean and quiet matters more than raw speed.
What are the four 2.5Gbps RJ45 ports for?
The SS-1 also has four 2.5Gbps RJ45 ports, which are the same style of Ethernet socket but capable of running at 2.5 gigabits per second, far faster than the 100Mbps ports. These give you flexibility to connect faster devices or to link into a quicker part of your home network.
Having a mix of slower and faster ports means the SS-1 can slot into different setups. You might bring your main network in on one of these faster ports, while keeping a slower, quieter port dedicated to the streamer. With six RJ45 ports in total, there is plenty of room to connect several devices.
What are the two 10Gbps SFP/SFP+ ports for?
The SS-1 includes two 10Gbps SFP/SFP+ ports, which are high speed slots that accept either fiber optic modules or RJ45 modules. SFP and SFP+ are a modular style of connection common in professional networking, and the "+" simply indicates the faster variant.
The interesting part for audio is fiber. A fiber optic connection carries data as light rather than electricity, which naturally breaks the electrical path between devices. That can be a very effective way to keep noise from traveling down the line. Because these slots accept the module you choose, you can run fiber where you want that clean break, or use an RJ45 module if you prefer a standard cable. This gives you real freedom in how you wire things up.
What Is Happening Inside
What does galvanic isolation on the network stage mean?
Galvanic isolation means the SS-1 electrically separates the incoming network from the outgoing connection, so noise on one side cannot flow directly through to the other. Picture a firebreak that stops something spreading from one field to the next.
In everyday listening terms, this is one of the main reasons the SS-1 exists. Your home network is a busy, electrically noisy environment. By isolating the network stage, the SS-1 helps prevent that mess from riding straight into your streamer. You do not need to configure anything for this to work. It is built into how the unit handles the signal.
Why does the high-precision internal clock matter?
The high-precision internal clock keeps the timing of the network signal steady and accurate, which reduces jitter. In digital audio, timing is everything. When the tiny timing pulses that organize data become slightly unstable, that instability can carry forward and affect the sound.
A better clock means more precise timing, and more precise timing means a cleaner handoff to your streamer. Again, this happens automatically. The clock simply provides a more reliable heartbeat for everything the SS-1 sends downstream.
Build Quality and Who It Suits
Why does Matrix Audio build quality matter here?
It matters because a device meant to reduce noise has to be quiet and stable in its own right, and Matrix Audio designs their products with that careful, considered engineering in mind. There is little point adding a box to clean up your network if that box introduces problems of its own.
Matrix Audio has a reputation for solid, well thought out digital gear, and that same attention carries into a product like the SS-1. Thoughtful internal layout, quality parts, and a focus on isolation and clocking are exactly what you want in a component whose entire purpose is refinement rather than raw performance.
Who is the SS-1 actually for?
The SS-1 is for anyone streaming music into a quality system who wants to squeeze more clarity out of what they already own. If you have a network streamer or transport and you have started to care about how your system sounds, this is the kind of upgrade that targets a part of the chain many people overlook.
You do not need to be a networking expert to benefit. If you are curious, enjoy your music, and want a clean and stable foundation feeding your streamer, the SS-1 is a sensible and refined place to invest your attention.
