LL7906 Lundahl microphone trasformer - +16dBU alto livello/ingresso linea

The LL7906 is a large, high level, high performance audio transformer, pin compatible with our LL17905, but with an internal structure better optimized for high turns-ratio step-up applications. The transformer combines very high secondary level capability (+37 dBU [54.5V rms] @ 50 Hz ) with low copper resistance. The LL7906 consists of two coils, each with two primary and one secondary windings separated by electrostatic shields. The core is a high permeability mu metal lamination core. The transformer is magnetically shielded by a mu metal case.
