RB500ME is a stereo passive equalizer packed into a double 500-series module. This beast is equipped with transformer balancing on inputs (Carnhill) and outputs (Edcor) as well as a discrete driver circuit. Of course the entire filtering section is passive and mirrors analogue equalizers from the 60s. There is separate frequency selector for low cut and boost sections. Top quality ELMA switches and pots were used to achieve outstanding performance.
