(This text is machine translated) Made in a shielding metal container, it allows both low-level and high-level interconnections to be made between audio systems that have hum or ground loop problems. Inside there is a transformer with galvanic isolation combined with a special circuit for signal adaptation. It also allows the relaunch of the signal taken from the constant voltage loudspeaker line, directly driving any amplifier connected to it at line / AUX level.
