ELIMINATING HUM AND BUZZ AND THE GROUND LOOP
The ISO-2 is equipped with output isolation transformers to eliminate hum and
buzz caused by stray DC voltage and ground loops.
Computers, CD players and other consumer equipment can be noisy
-
this
is particularly true when incorporating audio with a projector
-
so isolation
transformers can be very useful when combating system noise.
The independent Ground Lift switches on the outputs takes this one step further
by lifting pin-1 on the XLRs. Computers are often the source for noise problems
in audio systems, so greater care is certainly needed to keep things quiet.
