Line input transformers provide the maximum possible Common Mode Rejection of unwanted signals. All models have a single Faraday shield and a 30dB magnetic shield can. Models are available in 1:1, 1:1.4, 1:2, 2:1 and 4:1 ratios. Several models are also available as octal plug-in versions. This transformer has split primary and secondary windings which can be connected for 1:2 (150:600ohm), 1:1 (600:600ohm) or 2:1 (600:150ohm) operation. Distortion, although specified for 600ohm sources, will be further reduced by lower impedances. A 30dB magnetic shield package is standard.
