That's why we love this product
  • Eliminates annoying humming and noise:The ATG00101 ensures that humming and sound interference, which often occurs due to ground loops, are a thing of the past. Whether connecting a computer and speakers, TV and AV receiver or smartphone and car radio - this small device prevents annoying noises and ensures clear, interference-free sound.
  • Easy to use – No power supply required:The ATG00101 is particularly easy to use: you simply plug it between two devices and the annoying humming is a thing of the past. No additional cable or external power source is required - just plug in and enjoy.
  • Compact and unobtrusive:With its compact dimensions (only 6 x 2 x 2 cm), the ground separation filter can be easily stored and fits discreetly between your audio devices. This keeps your setup neat and tidy.

Das sagen unsere Kunden

What an audio ground isolator is used for

If 2 devices with protective contact plugs are connected via an audio cable, there is often sound interference. A compensating current that causes hum flows through the different ground potentials. Such devices can be, for example, computers and stereo systems. There is a similar effect if one of the devices is connected via an antenna connection, eg television, cable receiver, satellite receiver, car radio. In such cases, the audio ground isolator helps. The mass is galvanically isolated, so there is no longer any electrical connection between the devices. The audio signal is transmitted unaffected by this. This effectively removes background noise.

Filters in both directions

The ATG00100 works both ways and comes with a short connection cable. You can use it to connect the small adapter near the audio source or on the end device.

Small and compact

No power supply is required. Therefore, the audio mass separator can be placed inconspicuously.

Prevents hum in audio between powered devices

  • Galvanically isolates the masses in audio connections and thus removes hum and sound interference
  • For all audio connections with a 3.5 mm jack plug, e.g. computer, TV, car radio, smartphone, active speakers, Bluetooth receiver, stereo system
  • Eliminates ground loops without degrading sound
  • Is simply inserted between the devices and can be placed inconspicuously (size only 6 x 2 x 2 cm)
  • No power supply required, no additional connection cable required


The ground isolator is used as an audio filter and eliminates hum and sound interference. Such noise often occurs when connecting audio devices that are connected to the power supply with protective contact plugs, e.g. computers and active speakers, televisions and AV receivers, PCs and monitors. The cause is a compensating current that flows between the different potentials of the devices. The inductive transmission in the ATG00101 interrupts an electrical connection and prevents such disturbing currents ("50 Hz hum").

The ground isolation filter can also eliminate unwanted noise for audio connections in vehicles. There are sound problems in the car when music is played from the smartphone and it is being charged at the same time. The ATG00101 has real galvanic isolation. It is connected anywhere between the two devices using the included short audio cable (3.5 mm) jack. Due to the compact dimensions of 60 x 20 x 20 mm, the filter is easy to store.
