LL1571 Lundahl microphone trasformer +10dBU 200 ohm/2.5k ingresso microfono

LL1571 is a microphone input transformer built up from two coils and a high permeability mu metal core. Each coil is wound in three sections with electrostatic shields connected to separate pins. This result in a transformer with a very broad band, also ideal for splitting purpose. The two-coil structure in combination with the mu-metal can results in a high immunity to external magnetic fields
