ISO2X4
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.
OVERVIEW
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.
