Isolator4USB – HIGH-SPEED USB ISOLATOR for galvanic isolation

Galvanic isolation of USB 2.0 host and device

The Isolator4USB is a sophisticated device that isolates the data lines and power supply between a USB host and a USB device. This is achieved by using a powerful USB isolation chip in combination with a DC/DC converter. This design prevents interference noises such as crackling or dropouts in the audio signal, which often occur with improper connections.

The galvanic isolation eliminates unwanted electrical interference, resulting in a significant improvement in sound quality. The Isolator4USB is ideal for professional audio applications as well as for use in recording studios, live recording and the installation of hi-fi components, where interference-free signal transmission is of the utmost importance.

Features

High-performance USB isolation chip: Reliably isolates the data lines and prevents interference noises such as crackling, hum loops or dropouts in the audio signal.

Elimination of interference noise through galvanic isolation

Problem

In many professional audio setups, annoying interference noises such as crackling or dropouts occur in the audio signal. These problems can often be traced back to so-called ground loops, which are caused by the connection of several devices. These ground loops not only cause acoustic interference, but can also significantly impair the signal quality.

Solution

The Isolator4USB offers an effective solution here by galvanically isolating the USB interface. A high-performance USB isolation chip isolates the data lines and a DC/DC converter isolates the power supply between the USB host and device port. This ensures clear and interference-free signal transmission for optimum audio quality.

FAQs – Frequently asked questions about Isolator4USB

How does Isolator4USB work?

The Isolator4USB isolates the data lines and the power supply between the USB host and the USB device using a high-performance USB isolation chip and a DC/DC converter. This prevents interference noises such as crackling or dropouts in the audio signal, which are often caused by ground loops.

What advantages does Isolator4USB offer?

The Isolator4USB eliminates noise and dropouts in the audio signal, extends the maximum cable length of the USB interface and offers two modes for the power supply of the connected USB device: Self-Power (5V/400mA) and External-Power (5V/500mA).

What data rates does the Isolator4USB support?

The Isolator4USB supports data rates of up to 480Mbd, which corresponds to the maximum transfer rate of USB 2.0.

Can the Isolator4USB also be used with USB devices other than audio devices?

Yes, the Isolator4USB can be used with all USB devices that operate within the supported data rates and fulfil the corresponding current requirements. However, medical devices must not be connected.

How is the Isolator4USB powered?

The Isolator4USB can be operated in self-power mode (via the USB host) or in external power mode (via an external power source).

Does the Isolator4USB affect the performance of my USB device?

No, the Isolator4USB is completely transparent and does not affect the performance of your USB device. It merely ensures a clean separation of the data and power lines to eliminate interference.

Is the Isolator4USB compatible with all operating systems?

Yes, the Isolator4USB is compatible with all common operating systems, as it behaves like a normal USB cable and does not require any special drivers.

How do I install the Isolator4USB?

Installing the Isolator4USB is easy: simply connect it between the USB host (e.g. computer) and the USB device (e.g. audio interface). No additional drivers or software are required.

Can I use the Isolator4USB with a USB hub?

Yes, the Isolator4USB can be used with a USB hub as long as the total power consumption of all connected devices does not exceed the available current capacities.
