LL1922 High Level Stepup Line Input Transformer

LL1922 is a high-level input transformer similar to the UTC LS-10. Thus it is designed for step-up input from 600 ohm
sources. To reach the LS-10 freq. response in 1:8 applications with nondifferential amplifier input, the internal Faraday
shield must be tied to one of the source lines (the UTC LS-10 does not have any Faraday shield).
The two coils structure results in a high immunity to external magnetic fields from e.g. power supplies and motors.
Primary and secondary windings are separated by electrostatic shields. The core is a high permeability mu metal core.
The transformer is housed in a mu-metal can.
