    Problem Solver

    Overall: 5 out of 5

    This transformer is a real problem solver in large sound installations. If you have hum on a line level (+4 dbm) signal going to another area such as an over-flow room this is the answer. Be aware that the ground/shield wires from the two venues should NOT be tied together at the ground connection of the transformer. In most cases tie the transformer ground to the audio source ground only.
