LL1926 Lundahl microphone trasformer

LL1926 is an audio transformer with a variety of connection alternatives. It is designed for microphone input (step-up) applications, but can also be used as a line input step-down transformer. The transformer consists of two coils, each with one high impedance winding surrounded by two low impedance windings, with Faraday shields between all sections. The LL1926 has a mu-metal lamination core and is housed in a mu-metal can. The LL1926 is pin compatible with the amorphous core transformer LL1550, but LL1926 takes up more board space due to the shape of the mu metal laminations.
