The ME 1B is a single channel passive equalizer, with a tube based push-pull amplifier for restoring the gain.

A passive equalizer is variable equalizer requiring no power to operate. Consisting only of inductors, capacitors and resistors, it is favored for its low noise performance (no active components to generate noise), high dynamic range (no active power supplies to limit voltage swing), extremely good reliability, and lack of RFI interference. The equalizer provides low-frequency boost, mid-frequency attenuation and high frequency boost. To compensate for the inevitable gain loss, the filter section of the ME 1B is followed by a tube based amplifier.

The input and output transformers come with a static screen between primary and secondary wiring, and the input and output of the ME 1B are balanced and fully floating.
