High Performance Transformer from the renowned Lundahl Transformer company
LL1527A is a special split version of the classical microphone transformer LL1527, where the shields of the two coils are available on separate pins. 
This facilitates building of e.g. split boxes with galvanically isolated shields.
The LL1527 is built-up from two coils, each with one primary and one secondary winding separated by an electrostatic shield. 
Each shield is connected to a separate pin. The core is a high permeability mu-metal core and the transformer is housed in a mu-metal can.
