Line input/output or patchbay audio isolator module. This transformer has split primary and secondary windings which can be connected for 1:2 (150:600 ohms), 1:1 (600:600 ohms) or 2:1 (600:150 ohms) operation. Distortion, although specified for 600 ohms sources, will be further reduced by lower impedances.
