A USB DAC has one USB input, but most systems now have a laptop, a music server and perhaps a streamer that all want to use it. The SU-1 takes three USB sources, two Type-B and one Type-C, and routes any of them to either of two Type-A outputs at the press of a button.\u003c\/p\u003e\u003cp\u003eSwitching is only half of what it does. Computers are electrically noisy, and a USB cable carries that noise straight into the converter alongside the audio data. The SU-1 places a digital isolation chip between the input and output sides, so the data crosses but the electrical connection does not. The ground loop and the high frequency rubbish that rides on a computer USB port stop at the SU-1.\u003c\/p\u003e\u003cp\u003eThe output side is then powered independently by a toroidal transformer and a regulated supply rather than by the host computer, and each Type-A output can deliver up to 1000 mA. That matters for bus powered devices, and it means the power reaching your converter is clean and steady instead of whatever the computer happened to be putting out. The unit also supports cable runs of 4 to 8 m, so the source and the converter no longer have to sit next to each other.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThree USB inputs, two Type-B and one Type-C, feeding two Type-A outputs\u003c\/li\u003e\n\u003cli\u003ePress button switching between sources with input and output status LEDs\u003c\/li\u003e\n\u003cli\u003eDigital isolation chip breaks the electrical connection between computer and converter\u003c\/li\u003e\n\u003cli\u003eRegulated supply from a toroidal transformer rather than bus power from the host\u003c\/li\u003e\n\u003cli\u003eUp to 1000 mA per output for bus powered devices\u003c\/li\u003e\n\u003cli\u003eUSB 2.0 High-Speed throughout at 480 Mbps, so resolution is never the limit\u003c\/li\u003e\n\u003cli\u003eSupports 4 to 8 m cable runs for flexible placement of source and converter\u003c\/li\u003e\n\u003cli\u003eCompact 120 mm wide chassis that sits beside a DAC rather than dominating a rack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow the SU-1 Compares\u003c\/h3\u003e\u003ch4 style=\"font-size:1.15em;font-weight:800;margin:14px 0 4px\"\u003eMatrix Audio SU-1 vs Matrix Audio SI-1\u003c\/h4\u003e\u003cp\u003eThe SI-1 does for Ethernet what the SU-1 does for USB. It is an audio grade network isolator, so it sits on the network cable feeding a streamer and breaks the electrical path there. If your source reaches the system over Ethernet, the SI-1 is the right tool. If it reaches the system over USB, the SU-1 is. Systems that use both often want one of each. \u003ca href=\"\/products\/matrix-audio-si-1\"\u003eSee the Matrix Audio SI-1\u003c\/a\u003e.\u003c\/p\u003e\u003ch4 style=\"font-size:1.15em;font-weight:800;margin:14px 0 4px\"\u003eMatrix Audio SU-1 vs Matrix Audio SS-1\u003c\/h4\u003e\u003cp\u003eThe SS-1 is an audio grade network switch, so it manages and cleans several Ethernet connections at once. The SU-1 is the USB equivalent of that idea, managing several USB sources into a converter.

It takes three USB sources and routes any of them to either of two USB outputs, while galvanically isolating the output side from the input side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat problem does it solve?\u003c\/strong\u003e\u003cbr\u003eTwo problems. A USB converter normally has one input but you may have several USB sources, and a computer injects electrical noise into whatever it is plugged into. The SU-1 handles the switching and the isolation together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many sources can I connect?\u003c\/strong\u003e\u003cbr\u003eThree.

You select which input goes to which output from the front panel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does galvanic isolation actually do?\u003c\/strong\u003e\u003cbr\u003eIt passes the data across a digital isolation chip without passing the electrical connection. Ground loops and high frequency noise from the computer stop at the SU-1 instead of continuing into your converter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it limit resolution?\u003c\/strong\u003e\u003cbr\u003eNo. The SU-1 runs USB 2.0 High-Speed at 480 Mbps throughout, which is the same standard your converter expects, so the format and sample rate limits are set by the converter rather than by the SU-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it need its own power?\u003c\/strong\u003e\u003cbr\u003eYes, and that is the point. It runs from an AC supply with a toroidal transformer, so the output side is powered by a clean regulated source instead of by the host computer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much current can it supply?\u003c\/strong\u003e\u003cbr\u003eUp to 1000 mA per Type-A output, which is enough for bus powered devices that a computer port can struggle with.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use long USB cables with it?\u003c\/strong\u003e\u003cbr\u003eYes. Matrix Audio rate it for cable runs of 4 to 8 m, so your computer and your converter do not have to sit together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it work with a Mac and a PC?\u003c\/strong\u003e\u003cbr\u003eYes. It is a USB device that presents the host connection through to the converter, so operating system support is determined by your converter and its drivers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect a phone or tablet?\u003c\/strong\u003e\u003cbr\u003eThe USB Type-C input accepts a source that can act as a USB host, so it depends on the device and its software rather than on the SU-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I switch between sources?\u003c\/strong\u003e\u003cbr\u003eWith the front panel button. Three input LEDs and two output LEDs show you what is routed where at a glance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it change the sound?\u003c\/strong\u003e\u003cbr\u003eIt is not a tone control. What it removes is noise and ground loop related artefacts, which on a resolving system typically shows up as a quieter background rather than as a change in tonal balance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it the same as the SI-1?\u003c\/strong\u003e\u003cbr\u003eNo. The SI-1 is a network isolator for Ethernet. The SU-1 is for USB. Many systems benefit from both because they clean different paths.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is it?\u003c\/strong\u003e\u003cbr\u003e120 mm wide, 205 mm deep and 44 mm high, and it weighs 1.58 kg, so it sits comfortably beside a DAC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage does it run on?\u003c\/strong\u003e\u003cbr\u003eIt is built for either 100 to 120 V or 220 to 240 V and the voltage is set at the factory, so order the version for your region.
