About This Listing

The EQP501 is a passive equalizer based on the classic PULTEC EQP 1A, adapted to the '500' format of API*.

It is made of an all-passive section followed by a gain makeup stage based on a Discrete Op-Amp (DOA).

The EQP501 retains all the controls from the original but adds some new frequencies to the low and high sections.

Just install it in your API* compatible LunchboxTM rack and start recording.
