The ATG00101 effectively prevents humming and sound disturbances between powered devices by galvanically isolating the ground connection in audio connections. The ground isolator removes interference such as the typical 50 Hz hum, ensuring clear audio transmission without sound loss. It is suitable for all connections with 3.5 mm jacks, for example, between a computer and active speakers, a television and an AV receiver, a smartphone and a car radio, or stereo systems. The device eliminates ground loops without compromising sound quality. It simply plugs in between the devices to be connected and requires no power supply or additional connection cables. With a compact size of just 60 x 20 x 20 mm, it can be discreetly placed. The ground isolator is particularly useful in vehicles, where sound disturbances often occur when a smartphone is playing music while being charged. Thanks to the true galvanic isolation, these noises are reliably eliminated. Technical specifications: Impedance: 600 Ohms, frequency range: 20 Hz to 20,000 Hz, connections: 2 x 3.5 mm stereo jacks, bidirectional.
