Sonifex launch two passive line isolation units to drive signals over a long distance or protected from ground loop hums. Both of the new products are used to isolate audio signals from inter area ground hum loops, which could be caused by equipment being powered by different mains power supplies or phases on the same supply.By isolating the signal using transformers, ground loop currents that can be present in non-isolated signals, are eradicated completely.
The RB-PLI6 6 way mono passive line isolation unit has 6 inputs and 6 outputs which are connected together through a transformer. Internal jumpers allow the inputs and/or outputs to be balanced about ground and the unit requires no mains power for operation.
Sonifex RB-LI2 Line Isolation UnitThe RB-LI2 stereo line isolation unit has 2 inputs and 2 output which are connected together through a transformer. Internal jumpers allowing the outputs to be balanced about ground and there are also 2 loop-through outputs, so that the RB-LI2 can be inserted into a line, forming a transformer balanced stereo audio distribution point.
Sonifex products will be showing at 115th AES, booth #261 (Independent Audio).
