LL1578XL Lundahl microphone trasformer
Trasformatore per adattamento impedenza microfono 1+1 : 10 +13dBU 50 : 5 k Ω. Same pinout as LL1538. For low impedance source.
LL1578XL data
The LL1578 and the LL1578XL are high performance microphone input transformers/line-box transformers with high permeability mu-metal cores and high bandwidth coils. The LL1578 and the LL1578XL use the same pin-out as our well known microphone transformer LL1538. In the LL1578XL the core is about 45% larger than in the LL1578, resulting in a higher signal level capability. In both types, primary and secondary windings are separated by electrostatic shields. The very low leakage inductance and thus excellent frequency response is achieved by a two-coil, three-section per coil winding structure. The transformers are encapsulated in mu-metal cases for magnetic shielding
