Fairfield Circuitry The Accountant

  • No integrated circuits in the signal path Transformer-balanced input and output Selectable output transformer loading resistors by an internal T4-style electro-optical attenuator Very simple to operate with only two main controls, Gain and Peak Reduction A big meter shows gain reduction or output level at two different reference levels Hardwire bypass switch for easy comparisons XLR and TRS input and output jacks for flexible connections Link jack and switch for conne.
  • The COMP-3A is a single-channel vintage-style Compressor/Leveler.
  • The signal path uses only discrete components like resistors, capacitors and transistors, and the input and output is transformer balanced using two different transformers, each one optimized for its purpose.
  • This is the way audio components were built before integrated circuits became available.
  • Integrated circuits are small and cheap and widely used in most modern designs.
