Detaljebeskrivelse

LL1530 is a microphone input transformer used for matching a 200 or 800 W microphone to 10 kW or for
matching a high impedance source to a microphone input.
The transformer consists of two coils, each with one primary and one secondary winding separated by an
electrostatic shield, and a high permeability mu-metal core. The transformer is encapsulated in a mu-metal case
for magnetic shielding.
For best performance, the high impedance side of the transformer (3.5 + 3.5) should be connected in series.
