OVERVIEW

FEATURES

The ISO-2 is a passive audio isolator designed to be inserted into the signal 
chain to block hum and buzz caused by ground loops. The ISO-2 accepts 
unbalanced or balanced signals and is equally suitable for consumer 
electronics and professional line-level devices.

The ISO-2 can be operated as a dual input and outputs, and since the circuit 
is passive, no power is required. Whether an unbalanced or balanced signal 
is connected, the ISO-2 will automatically convert the signal depending on 
the type of cable and connector plugged in.

The ISO-2 is a simple passive device, designed to electronically-isolate 
connected line-level audio equipment without degrading the audio quality.

On the ISO-2 there are 2 inputs and 2 outputs which block DC voltage and 
prevent buzz and hum from ground loops. Both outputs feature individual 
ground lift switches to help further reduce ground loop noise.
