Turns ratio: 1 + 1 + 2 + 4 : 1 + 1 + 2 + 4
LL2414 is a high inductance line transformer for connecting PA system loudspeakers to power lines. The transformer is based on the very flexible (too flexible?) LL2410, but sectioning is reduced to facilitate usage in most applications. The eight windings can be combined in a number of ways, but symmetry between coil 1 and coil 2 is essential for good performance.
The transformer has a special audio C-core of our own production.
