Rebis RA204 Parametric Equalizer

The Rebis RA204 Parametric Equalizer is one of the many modules available for the Rebis Rack Effects system based on the Vero card frame system. The RA204 is a single band fully parametric equalizer with +/-21db of boost and adjustable resonance (bandwidth) and center frequency. The frequency control covers a 100:1 range and works with a x10 switch to allow coverage of the entire 20Hz to 20kHz audio spectrum. The unit features a bypass switch for taking the equalizer in and out of the audio path. I think the RA204 sounds just fine, but is not to be mistaken for an EQ module from an API, Neve, or even SSL. I often relinquish the RA204 to duties in a sidechain of a compressor or gate than actually manipulating audio.
