ISO-MAX isolators with an “O” in the model number (PO-2XR, for example) are most useful when driven by a balanced equipment output and a good choice when driving long cables. The isolator output can then feed either balanced or unbalanced equipment inputs with no risk of damage or misbehavior in the driving equipment, regardless of what kind of output stage it uses. These provide a reduction in low frequency “ground loop” hum but little effect on high frequency buzz.
