DIY Recording Equipment

The EQP5 is a premium tone-shaping EQ based on the prized Pultec EQP filter circuitry.

The World's Most Musical Filters. The EQP5 employs the passive filter circuitry made famous by Pultec's legendary EQP series of equalizers. Decades after their introduction, these EQ's remain coveted for their uniquely musical and natural behavior.

Modern Clarity or Vintage Tone. Choose between a clean and modern or vintage and colored output stage. If both outputs are installed, you can switch between them with a solderless jumper on the board.

The Modern (stock) output is a clean, robust, balanced output for excellent noise performance. Choose this output to use the EQP5 for transparent, natural tone-shaping.

The optional Vintage output employs an API-style DOA (discrete opamp) and custom transformer for a livelier dynamic character. The vintage output gives signals a more visceral, forward feeling that helps them translate clearly in a mix while requiring less level to do so. The solid-state Pultecs, the sound of which many engineers claim to be sweeter than that of the earlier tube units, use the same DOA/transformer output scheme.

Designed for DIY. The EQP5 was designed from the ground-up to be a satisfying DIY project. Our photo manual will guide you through every step of the assembly. And the circuit board contains extra capacitor and inductor footprints for customizing the frequency bands.
