Hi Mark. The noise canceling units use phase inversion to cancel noise. They work okay on noise coming from a singe point source. However, they don't seem to work well on noise generated from multiple sources or a spread out source as noise will then arrive in different phases.
DX Engineering's '2 Channel' feature might allow canceling from a second source, but that's a bit beyond my understanding. If it is possible to determine the type of noise you are receiving, you may save yourself some money. Some investigation with some noise detecting equipment (if you don't have to pay for the equipment) may be fruitful.
