The ISO2X4 is a passive audio isolator/splitter designed to be inserted into the signal chain to block hum and buzz caused by ground loops. The ISO2X4 accepts unbalanced or balanced signals and is equally suitable for consumer electronics and professional line-level devices.

The ISO2X4 can be operated as a dual 2 outputs splitter or the 2 inputs are summed to form a mono 4 outputs splitter, and since the circuit is passive, no power is required. Whether an unbalanced or balanced signal is connected, the ISO2X4 will automatically convert the signal depending on the type of cable and connector plugged in.
