Turns ratio: 1 + 1 : 1 + 1. High-level, general-purpose transformer with an amorphous core which can be used for microphone or line input as output and for galvanic isolation. 10Hz to 100Khz Frequency, very linear response.
The windings are arranged for perfect symmetry if the transformer is used in phase splitting input applications. The two coils structure also greatly improves immunity to external magnetic fields from e.g. power supplies. Primary and secondary windings are separated by electrostatic shields. The transformer is housed in a
mu-metal can.
