High Level Line Input Transformer
LL1592
LL1592 is a high-level line input  transformer with a mu metal lamination core. The transformer is designed for high end
pro audio line input applications with or without phase splitting. The windings are arranged to give a high degree of
symmetry if the transformer is used for phase splitting. The dual-coil structure also greatly improves immunity to
external magnetic fields from e.g. power supplies and motors. Primary and secondary windings are separated by
electrostatic shields.. The transformer is housed in a mu-metal can.
Turns  ratio:                                            1 + 1 : 1 + 1
