823 Pultec type Equalizer

The EAR 822Q Pultec type equalizer has been designed to be highly flexible and thus useful in a wide range of applications. Passive equalization networks combined with valve input and output buffers are used in order to minimize disturbing side effects such as phase shift and ringing.

The EAR 823MQ is a variant of the 882Q designed for use in the mid-band. It is slightly simpler with the frequencies set closer together in order to give more precise control over this critical spectrum.
