Line Input Transformers

Carnhill’s range of line input transformers


Typically used to balance any high impedance unbalanced input, for eliminating hum and buzz in line-level signals, Faraday-shielded input transformers are the preferred solution. Transformer-less inputs suffer “breakthrough” noise in electrically-hostile environments, but transformers are unaffected.
