The Tube-Tech PE 1C Program Equalizer contains a low frequency boost and attenuation section (shelving), and a high frequency boost section (peaking). The high frequency section has variable bandwidth as well as attenuation (shelving). The filter section is of the passive type followed by a tube based push-pull amplifier to restore the gain.
Input and output are balanced as well as fully floating. Input and output transformers come with a static screen between the primary and secondary wirings.
