LL1527 General Purpose Transformer

LL1527 is a truly general purpose transformer for microphone or line input, for output, for splitting 1 direct + 1 isolated
and for galvanic isolation of units. LL1527 has been generally accepted by the audio industry as the general purpose
audio transformer. The LL1527 is built-up from two coils, each with one primary and one secondary winding separated
by an electrostatic shield. The core is a high permeability mu metal core. The transformer is housed in a mu-metal can.
In the LL1527XL, the core is about 45% larger than in the LL1527, resulting in a higher signal level capability.
Turns ratio: 1 + 1 : 1 + 1
