Input and DC-free line output applications
Line input and line output transformers for galvanic isolation, balanced-to-unbalanced conversion and for impedance conversion. Should be used with DC-free signal sources, or with a DC blocking capacitor between source and transformer.

High level general purpose
|
For high level, low impedance applications such as (DC decoupled) line output.
The transformer is not suitable for line input from high impedance signal sources.
