Tube Tech ME-1B Passive Midrange Tube Equalizer

The TUBE-TECH ME-1B is a mono passive tube based midrange equalizer developed to match and surpass the demands of even the most discerning studio engineers.

The ME1B contains a low frequency boost section for peaking, a mid frequency attenuation for dipping as well as a high frequency boost section for peaking. The filter section is of the the passive type followed by a tube based push-pull amplifier to restore the gain.

Input and output are balanced and fully floating. Input and output transformers come with a static screen between the primary and secondary wirings.
