Manley Enhanced Pultec Mid Frequency Equalizer

Learn More

The REQ is a combination of passive filter circuits and active amplifier stages. Parallel resonant chokes and capacitors form the frequency selective part of each band and these are coupled into the amplifier stage via the boost/cut control. The resulting equalisation is best described as "surreal" and it never sounds hard or harsh. The low frequencies remain tight and powerful with the high frequencies clear and well defined.

The MANLEY ENHANCED PULTEC EQP-1A is our own interpretation of the historic Pultec Equalizer as originally produced by Pulse Techniques, Inc. We have been building these Manley Pultec EQs since 1990 after we bothered to hunt down Eugene Shenk in New Jersey to ask for his permission and blessings to produce our own version of his classic piece. These Manley Pultec units employ our own simple and clean all-tube make-up gain block to reamplify the signal after the passive EQ circuit.
