High Performance Splitting Transformer from the renowned Lundahl Transformer company.
The LL1570XL is designed for splitting signals in application where large ground differences may appear, but is also veryuseful as a general purpose audio transformer. 
By careful design, the capacative coupling between the different part ofthe transformer is kept to a minimum. 
The three-section winding structure which is necessary for decoupling also resultsin a very high bandwidth. 
The transformer is built up from two coils, each with primary and secondary windingsseparated by electrostatic shields, and a high permeability mu-metal core. 
The two coil structure in combination with themu-metal can results in high immunity to external magnetic fields. 
In the LL1570XL, the core is about 45% larger than in the LL1570, resulting in a larger level capability
