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.

Technical data:

  • Impedance 600 ohms
  • Frequency range 20 ... 20,000 Hz
  • Connections: 2 x 3.5 mm stereo jack, bi-directional

Top Funktioniert endlich wirklich.

Endlich ein Filter der auch Funktioniert.
Nicht wie der ganze Kram auf Amazon, Ebay und Co.
Nicht noch mehr Störungen als man schon hat, wie bei den Dingern von Amazon.
Ich habe es für mein Auto gekauft ,da ich Lima Pfeifen am Original Radio und dem Aux Eingang hatte.
Ist nun weg und der Sound hat sich sonst nicht verändert. Bei anderen wird er gerne Mal leiser oder der Tiefton wird mit gefiltert.

Also kann ich wärmsten empfehlen das gute Gerät.

So simpel einfach und doch so genial

Man kann sich gar nicht vorstellen was ich schon alles versucht habe um Brummschleifen zu eliminieren. Nie richtig weg bekommen. Immer war noch irgendwas zu hören. Ausgangslage: TV oder Blu-ray Ton soll über reinen Analogen Stereo Verstärker wiedergegeben werden. Problem: über die Masse der Satelliten Zuleitung wird eine Brummschleife erzeugt. Der Ton (analog) über die Stereo Anlage ist leicht verbrummt. Auch sonst kann man ein ganz leichtes Brummen über die Stereo Anlage wahrnehmen (selbst wenn der TV aus ist). Den ATG00100 in die Zuleitung gesteckt und Ruhe ist! Der Ton ist nicht anders als vorher. Was will man mehr! Ich hätte fast ein 2. Filter gekauft und aufgemacht, da ich neugierig bin, was da in aller Welt für eine Technik drin ist. In der Fragen oben wird es beantwortet, galvanische Trennung mittels Übertrager! Vergesst alles was es an Mantelstromfilter usw. gibt. ATG00100 und Ruhe ist! Danke Feintech!

Audio interface Problem gelöst

Ich hatte immer Probleme bei der Ausgabe von Audio vom Rechner über ein Audiointerface an einen Verstärker, es gab immer seltsamsten Grundgeräusche, bedingt wahrscheinlich durch ein unsauberen Netzteil.
Mit dem kleinen Trennglied vonFeinTech gibt es keine Geräusche mehr, eine echt tolle Sache. Vielwn Dank, auch für die schnelle Zusendung dieses effektiven Gerätes.
