Behringer has just launched its “tribute” to the classic Moog analog audio gear with the BODE Frequency Shifter 1630 in Eurorack format.
Claiming to be an authentic recreation of the famous ’70s module, it features state-of-the-art circuitry including a voltage-controlled beat frequency quadrature oscillator.

It can accurately shift the entire frequency spectrum of an input signal from -5 to +5kHz, in either linear of exponential scaling. The variable threshold squelch control minimises carrier bleed through and can be used to creatively alter the input signal’s characteristics. Up to three control voltages can also plugged in, as well as up to four output signals.
What was the original Moog design?
As the original documentation says, a frequency shifter is an audio signal modifier which shifts the entire frequency spectrum of the
applied signal by a given amount. The Model 1630 Bode Frequency Shifter allows the amount of shift to be accurately and continuously controlled over a span of -5000 Hz to +5000 Hz, utilising voltage and/or manual control.
The relationship between the control voltage sum and the amount of shift may be either linear or exponential. Up-shifted and down-shifted outputs, as well as a continuously variable mixture of the two, are available simultaneously and independently.
Applications include a wide variety of tone color modification, PA feedback suppression, linear frequency modulation, novel tape feedback effects, and the generation of dynamically varying clangorous tones.
