The ISO2X4 is a simple passive device, designed to take a line-level audio signal and split it to separate destinations without introducing noise or degrading the audio quality.

On the ISO2X4 there are 2 inputs and 4 outputs, it is designed to be operated as a dual 2 outputs splitter, or mono 4 outputs splitter; in dual 2 outputs splitter mode, the input-1 audio will be split into 2 separate outputs which are the output-1&2, while the channel-2 audio input will split into separate outputs 3&4; in mono 4 outputs splitter mode, the 2 audio inputs are summed and then split into 4 separate outputs 1, 2, 3 & 4. Each isolated output pass through a premium transformer, which blocks DC voltage and prevents buzz and hum from ground loops. All of the outputs feature individual ground lift switches, which help further reduce ground loop noise.
