EAR 822Q Pultec Type Equalizer ParticularsThe Esoteric Audio Research EAR 822 is a Pultec-type passive mono equaliser (with valve electronics providing unity-gain buffering) for general-purpose studio EQ responsibility. The 823 has different (more very closely spaced) center frequencies for its controls however follows similar concepts.
The EAR 822 EQ Pultec kind equaliser has been made to be very flexible and hence helpful in a broad variety of applications. Passive equalisation networks combined with valve input and output buffers are utilized in order to reduce troubling adverse effects such as phase shift and ringing. The audio circuitry conforms to the EAR concepts of simpleness and subjective transparency, with low distortion at all typical signal levels. A “clickless” bypass switch enables effortless contrast between the processed and direct paths. Variations in feedback include reasonable pass, high pass, band pass and high or low frequency rack with variable Q and turnover regularity.
