Intona 7055-D USB 3.0 Hi-Speed Isolator Extended Isolation 5kV

The Intona SuperSpeed isolator supports USB full speed 12Mbps, hi-speed 480Mbps and also SuperSpeed 5Gbps. It provides galvanic isolation between the USB host and device and protects the device from power shocks and avoid ground loops that can be very troublesome in audio.

It supplies the connected device 500mA (same as standard USB port) without any additional power supply, or you can connect external power and deliver up to 2000mA. This version support 5kV signal and power isolation and 20kV ESD protection.

Model: 7055-D

What is the difference from the cheaper USB isolators?

The 7055-D supports in addition to full speed 12Mbps and Hi-speed 480Mbps also SuperSpeed 5Gbps. The main difference from the 7055-C is that the 7055-D model support 5kV isolation. For audio use this is generally not important and the 7055-C model might a better as it has lower DC noise. 

Does it require a driver or special setting?

No. Similar to a USB hub, the isolator is “transparent” to the computer and doesn’t require any driver or configuration in settings.

Does it support asynchronous USB?

Yes it supports all USB types, the isolator doesn’t care, it just passed on the data to your computer.

Will it improve the sound quality from my DAC?

It depends on your DAC, computer and electrical environment. If you have a ground loop then it will be removed by using a USB isolator. Additionally the isolator will clean up the 5V DC from your computers USB port. Some computers have very noisy USB power, while other are not so noisy, so the difference will depend on the starting point. This model isolator provides super clean DC supply with ultra low noise.

Is it sure to fix the noise I’m getting from my sound card/microphone/midi keyboard/other device?

It will fix noises that are caused by ground loops, often presented as whining, buzz or loud shh noises. However some noises have other causes. For example the microphone preamp might be noisy by itself, or an electric guitar might pick up noise in the air from other equipment. For those noises USB isolation and better quality, low noise DC power will probably not help much.
