Sonifex

The 1 RU Sonifex RB-PLI6 6-Way Mono Passive Line Isolation Unit passive line isolation unit is used to isolate audio signals from inter-area ground hum loops, which may be caused by equipment being powered by different mains power supplies or phases on the same supply. This unit is useful where audio is required to be driven over a relatively long length of cable. By isolating the signal using transformers, ground loop currents which can be present in non-isolated signals, are eradicated completely. The input and output are connected through a transformer, and the unit has internal jumpers allowing the inputs and/or outputs to be balanced about ground. The unit requires no mains power for operation.
