This small PCB is designed for some common applications using a few of our pin compatible transformer models. Typical applications would be galvanic isolation or balanced-to-unbalanced conversion. The PCB can be used in combination with a DIN housing, or can be screw mounted without any housing.In addition to the transformer, the board has two holes for mounting screws (3,2mm) and positions for screw or spring terminals.

Suggested use:
Galvanic isolation, Line Input, Balanced-to-unbalanced conversion, ratio 1:1 – LL1527 or LL1591
Microphone Input, ratio 1:2.5 – LL1528
Microphone Input, ratio 1:3.5 – LL1530
High level line Input, ratio 1.1 – LL1540
