Cet adaptateur DS Tech SH-G01C utilisé entre un ordinateur Apple et un DAC Hifi, restitue le son avec un rendu très légèrement différent, peut-être avec plus de clarté, mais cette impression reste toutefois subjective ! Dans mon cas, cet adapteur a l’avantage de libérer un port USB-A en échange d’un port USB-C utilisé par celui-ci. Qui peut le plus, peut le moins… cet adaptateur me sera utile selon les configurations utilisées (dans le meilleur des cas, il pourra réduire certaines interférences ou améliorer légèrement la propreté du signal), d’autant plus qu’il est compatible avec le signal numérique Hi-Res (PCM 32bit/768kHz, DSD512).Dans de bonnes conditions du système informatique / audio (comme ma configuration), l’impact de l’isolateur est très minime voire imperceptible, par contre effectivement, cet adaptateur peut apporter une amélioration notable, notamment pour les configurations PC sensibles – par exemple lorsque des interférences de masse ou un bruit induit par l’alimentation USB perturbent le signal – l’isolateur USB peut réellement améliorer la clarté sonore, parfois comme annoncé, de l’ordre de quelques décibels.Le mode d’emploi est malheureusement illisible et en anglais : il ne s’agit que d’une photocopie de mauvaise qualité… Un code QR permet de consulter une description sur le net, qui correspond finalement exactement au même contenu que la description sur Amazon !

La qualité de fabrication de cet isolateur est bonne.Le principe est simple : dans un ensemble de liaisons électriques formé par un ordinateur, ses périphériques USB, et tout le matériel raccordé, le référentiel à la masse est censé être le même pour tous les éléments de la chaîne, et cet accessoire va rendre l'ordinateur sur lequel il est branché "flottant". Pourquoi faire ça ? Pour l'isoler et le rendre insensible aux problèmes engendrés par la multiplication des masses pas toujours identiques, ce qui génère les fameuses "boucles de masses" si redoutées en audio. Autre usage intéressant pour les outils de mesure, isoler le port USB de l'ordinateur va permettre à un oscilloscope raccordé en USB de faire des mesures sur le "côté primaire", ou tout simplement sur le secteur. Sans cet accessoire, une mesure comme celle-là détruirait l'ordinateur à coup sûr en l'absence de sonde différentielle.Je suis donc satisfait de ce produit. Il s'avère indispensable dans certains cas de figure pour assurer la sécurité du matériel et des utilisateurs. Bien sûr, nous sommes ici en présence d'un accessoire à l'usage très spécifique, mais il fait parfaitement son travail quand on en a besoin. Vendu moins de 50€, le rapport qualité/prix me semble correct pour un isolateur 100% compatible USB 2.0 à 480Mbps.

This product is a lifesaver. I was dealing with UNBEARABLY loud electric hum from my guitar going into my audio interface. It made anything I recorded unusable and was nearly as loud as the guitar itself. Nothing I did to mitigate it worked.Well, I plugged my interface into this device, and now, the hum is effectively gone. Any remaining hum I can manage by angling my guitar away from my computer, and it is nowhere near the same level as the hum I was dealing with before.Before, I was skeptical, but I'm surprised how well it works. Note that this device is only made for electric hum that arises from one specific ground loop scenario, so if your hum is not caused by that, then the device will not help you. But if your problem is the same as mine, it really DOES do its job well.

For anyone who frequently connects their laptop or tablet to external devices via USB, it’s essential to understand the risks that come with such connections, particularly when those devices are powered by their own supply. While it might seem like a simple setup to plug into, this configuration can result in serious issues, particularly when ground loops are involved. Ground loops are electrical faults that can lead to malfunctioning components, and in some cases, they can cause irreparable damage. Having had the misfortune of damaging a USB interface on my laptop and even a critical AIS transceiver, I can personally attest to the destructive power of ground loops. This is where a USB isolator, such as the **DSD TECH SH-G01C USB-C 480M high-speed isolator**, becomes indispensable.At its core, a USB isolator serves a crucial function: it completely isolates the two devices from each other while allowing signals to pass between them. This means no current can flow from one device to the other, effectively preventing the creation of ground loops. This isolation is particularly beneficial when connecting devices that have their own power sources, which are more likely to generate the sorts of issues that could lead to the destruction of vital components. By employing an isolator, the risk of damage is significantly reduced, and the devices can communicate without the fear of creating electrical faults.Now, let’s take a closer look at the **DSD TECH SH-G01C** and see how it fares in the isolator market. One of the most important aspects to consider is the communication speed the isolator supports. This device can handle USB connections with speeds of up to **480 Mbps**, which is ideal for many low to moderate-demand applications. Whether you're configuring devices or making undemanding connections, the SH-G01C provides the necessary functionality. However, for high-speed data transfers or tasks that require more bandwidth, you may find the 480 Mbps speed somewhat limiting. If you're hoping to use it for high-performance tasks like transferring large amounts of data or running high-speed peripherals, you might want to look for an alternative.The technical specifications are worth noting, particularly for those who want to dive into the finer details. The SH-G01C uses the **ADI ADUM3165** chipset, which is a reliable component known for its efficiency in providing voltage isolation. The isolation voltage of **1500V** is a reassuring feature, ensuring that the device offers excellent protection against electrical surges and potential damage. As for the power input, it requires a steady **5V**, which is standard for most USB isolators and doesn’t put additional strain on your devices.What’s particularly nice about this model is the compatibility it offers. It supports **low (1.5 Mbps), full (12 Mbps), and high-speed (480 Mbps)** USB communication, making it versatile enough to work with a variety of devices. Additionally, it works across multiple platforms, including **Windows 7, 8, 10, and 11**, **Mac OS**, and **Linux**, ensuring broad compatibility regardless of your system. For those who enjoy their music or audio gear, it also supports **PCM 32bit/768kHz** and **DSD512 Native** audio, which can be a major plus for audiophiles or anyone who uses high-quality audio equipment.When it comes to build quality, the SH-G01C doesn't disappoint. The device is well-constructed, with a solid, durable design that can withstand regular use. The inclusion of both **USB-A and USB-C ports** provides additional flexibility, ensuring that it works with a wide range of devices. Whether you need to connect to older USB-A devices or newer USB-C ones, this isolator has you covered.There are, however, a couple of considerations to keep in mind. While the device works as advertised and provides a valuable service in protecting your equipment from damage, the speed limitations of 480 Mbps could be an issue for users requiring faster data transfer speeds. Additionally, the isolator is designed for lower-demand tasks, so it might not suit those looking to use it for high-performance connections or professional-level data transfers.In conclusion, the **DSD TECH SH-G01C USB-C isolator** is an excellent, cost-effective solution for those who need to protect their equipment from the dangers of ground loops. It offers solid performance, versatile compatibility, and a robust build, making it a great addition for anyone who works with devices that could potentially cause electrical issues.

While the 480 Mbps speed limit might not suit all users, for the average consumer or enthusiast, this isolator does exactly what it promises, and it does it well.

El fabricante nos remite este aislador USB-C a USB-A en un pack bien protegido.En el momento en que lo tenemos en la mano, podemos comprobar que está bien construido, resaltando en especial las uniones entre el conector USB-C y el cable, que se encuentran reforzadas evitando así que se dañe el producto ante algún tirón accidental. Es de tamaño pequeño y el diseño es muy original, ya que está fabricado en material plástico transparente y permite ver la circuitería del dispositivo.El aislador es plug&play, y en el momento en que quede conectado veremos que un led de color rojo se enciende en su interior. Podemos conectar cualquier dispositivo con conector USB-A. Una vez conectado, podemos tanto suministrarle alimentación como transferir datos, pero contando con la seguridad de que no vamos a sufrir sobretensiones, o en el caso de conectar algún dispositivo de audio evitaremos ruidos de interferencias.Hay que tener en cuenta que la velocidad máxima de transmisión de datos está limitada al estándar USB 2.0 (480Mbps).En mi caso lo utilizo para alimentar con seguridad una placa de desarrollo del tipo ESP32. También he probado a conectar el dispositivo a un transmisor DAC, y a simplemente transferir datos entre un teléfono Xiaomi Mi10 (Android) y un PC. En todos los casos ha funcionado perfectamente.En cuanto al precio, teniendo en cuenta la versatilidad del aislador, la seguridad que nos da y su funcionamiento, lo recomiendo. He quedado muy satisfecho.

Ho usato questo isolatore USB in modo forse non del tutto ortodosso, ma comunque ottenendo ottimi risultati.Nel mio caso avevo problemi con un PC fisso su quale uso un dongle bluetooth per connettere mouse, tastiera, cuffie e gamepad senza fili.Il dongle risentiva di disturbi ad alta frequenza che passavano dalla porta USB alla parte radio del bluetooth con lag, perdite di connessione ed altri disagi.Avevo in parte migliorato la situazione alloggiando il dongle in una porta 2.0, ma con questo isolatore la situazione è enormemente migliorata. La chiavetta funziona perfettamene ed ora anche la ricezione è ottimale e priva di lag.Un prodotto quindi utile e versatile, sicuramente prezioso per l'ambito hi-fi per cui è stato progettato, e versatile al punto giusto per rendere bene anche in altre condizioni. Non costa poco, ma è efficace: 5 stelle meritate.

Wenn man seinen Laptop oder Tablet via USB mit einem Gerät verbindet, das eine eigene Stromversorgung hat, kann das zu rösseren Problemen bis hin zur Zerstörung von Bauteilen führen, weil man dadurch Masseschleifen erzeugen kann. Die wiederum führen zu Störungen und manchmal auch zu größeren Strömen, die Bauteile zerstören können. Mir sind so schon eine USB Schnittstelle am Laptop und ein AIS Transceiver abgeraucht.Genau dafür braucht man einen USB Isolator: der trennt die beiden verbundenen Geräte galvanisch komplett, die Signale werden aber übertragen. Langsame für Konfiguration und anspruchslose Verbindungen gibt es einige, schnelle mit hohen Übertragungsraten nicht so viele.Und in genau diese Kategorie fällt der "DSD TECH SH-G01C USB-C 480M Hochgeschwindigkeits-Isolator": er unterstützt USB mti high speed, also mit einer maximalen Kommunikationsgeschwindigkeit von 480 Mbps.Die Spezifikationen sind nicht ganz leicht zu finden, liegen aber auf der Website von deshide(punkt)com.
