Tube Tech PE-1C Passive Program Equalizer

The TUBE-TECH PE-1C is a passive tube based program equalizer designed to meet the exacting standards of even the most demanding studio engineers.

The 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.
