Connection of audio isolation transformer

1. Single-ended connection: Connect the anode and cathode of the input signal to the input end of the isolation transformer, and the output end of the isolation transformer is connected to the output end equipment, such as amplifier or loudspeaker.

2. Double-ended connection: Two isolation transformers are used, one for input signal (input terminal) and the other for output signal (output terminal). The anode and cathode of the input end are respectively connected to the isolation transformer, and then the anode and cathode of the output end are respectively connected to the output end of the corresponding isolation transformer. This connection not only eliminates grounding noise and electromagnetic interference, but also further reduces signal distortion and distortion.
