The Intona USB Hi-Speed Isolator is the antithesis of glitzy packaging. The two most common reasons for creating isolation are safety from fault conditions in industrial grade products and where wired communication between devices is needed but each device regulates its own power. Generally referred to as “isolation”, galvanic isolation is the convention used whereby individual parts of the electrical system may possess different ground potentials. Energy or information can still be exchanged between the sections by other means, such as capacitance, induction or electromagnetic waves, or by optical, acoustic, or mechanical means. Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow, so that there are no direct conduction paths. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, are blocked. Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents. Its insertion in a data line will break ground loops, avoid noise coupling, and protect ports from power surges and voltage spikes, in applications which require high speed USB signal transfers. Their new product - claimed to be a world first - is designed to galvanically isolate the USB 2.0 Hi-Speed bus. Intona Technology is a German team specialising in signal processing devices for professional applications.

Some devices will require more than 200mA and will not work with the USB isolator. USB ports can supply up to 500mA of power, while the USB isolator will output max 200mA.Some further explanation (also see our USB isolator guide) Your device does probably either require too much power, or needs USB High speed mode (480Mbps). However, it doesn’t work with all USB devices. The USB isolator is “transparent” for the computer, so there are no drivers to install. It doesn’t work, do I need to install a driver? We have return addresses in USA, UK, Germany and China. We will ask you to pay shipping cost for sending the item back. Yes, we offer a 1 year warranty on all our products. New High-Speed isolator available here: Hifime High-Speed USB Isolator (supports samples rates above 96/24) ![]() This might be if they have a headphone amplifier, or a MCU that draws more power. It works with dac’s that support up to 96kHz/24bit, it does not work with 192/24 sample rates.Īlso, some dac’s require more than 200mA power. We do accept returns when it doesn’t work or remove the noise from your device. However the noise you’re experiencing might be caused in another way and might not be removed by the isolator. Will the USB Isolator get rid of my noise?īuzz noises are often ground loop problems, and this is exactly what the USB isolator will remove. Does not work with Focusrite sound cards!.Confirmed working with Prophet 12 synthesizer and other synthesizers (for MIDI). Works with M-Audio MKII card, and most USB mics.Some computers will not wake up the isolator after sleep/standby, require to disconnect and reconnect the isolator. ![]() You need to open the box and move both switches to the L position. Supports Low speed devices (mouse, keyboards, some midi converter) through internal switch.DOES NOT WORK WITH multi channel DACs/sound cards.New High-Speed isolator here: Hifime High-Speed USB Isolator ![]()
