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 is designed for use in wideband line input stages. Distortion remains very low and CMRR remains high, even when driven by high source impedances. The primary is fully balanced and its leads may be reversed to invert polarity, if required. A 30dB magnetic shield package is standard.
