LL1952 Dual (Consumer or Professional) Line Input Transformer

The LL1952 is an input transformer with dual primaries (1:4 stepup or 1:1 line input), for equipment which can
be used with both consumer and pro audio signal sources. The purpose is to handle signals from both consumer
type equipment (1:4) and professional type equipment (1:1) while compensating for the different signal levels.
The input signals can be either unbalanced or balanced independently, for instance when using a hybrid
connector (XLR and jack) input.
As usual for our input transformers, primary and secondary windings are separated by Faraday shields.
The transformer is encapsulated in a mu-metal housing for magnetic shielding.
