The EQP5 is a premium tone-shaping EQ based on the prized Pultec EQP-1A3 filter circuitry. It's a single slot 500-Series mono EQ with high frequency cut and boost, as well as low frequency cut and boost. This is a very natural sounding shelving EQ perfect for individual channel or mix-bus operation. Don't let the price fool you, this unit can stand up alongside high end studio gear, including original Pultec equalizers. Although this is a passive unit, the makeup gain section is active as in the original Pultec design.
The World’s Most Musical Filters. The EQP5 employs the passive filter circuitry made famous by Pultec’s legendary EQP series of equalizers, specifically the EQP-1A3. Decades after their introduction, these EQ’s remain coveted for their uniquely musical and natural behavior. Even aggressive tone settings sound musically appealing. Pultuc equalizers have been faithfully recreated by many audio plugin manufacturers like UAD, however software plugins do not compare to the quality of the EQP5 analog hardware.
Modern Clarity or Vintage Tone. Choose between a clean and modern or vintage and colored output stage. If the Vintage Option is installed, you can switch between them with a solder-less jumper on the board. The Modern (standard) output is a clean, robust, balanced output for excellent noise performance. Choose this output to use the EQP5 for transparent, natural tone-shaping.
The Vintage Output (optional) employs a 2520 style DOA (discrete opamp) and custom iron core transformer (typically employed in 70's era studio consoles) 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.
