For more than 70 years, Pultec has defined what engineers mean by warmth, depth, and musicality. From the first EQP-1A in 1951 to today’s modern studios, no other equalizer has achieved such a perfect balance between precision and soul.
Now, thanks to Universal Audio, this legendary sound lives on in the Pultec Passive EQ Collection, available for both UAD-2 DSP and UADx native platforms.
A faithful recreation of an audio icon
After more than a decade of detailed research and modeling, Universal Audio has captured every nuance of the original Pulse Techniques hardware — from the transformers and passive circuits to the unique tube amplifiers that made the originals breathe.
The result is not just an emulation, but a living, breathing recreation that behaves and sounds like the real thing, bringing that unmistakable Pultec “glow” straight into your DAW.
The unmistakable Pultec sound
The Pultec EQs have long been celebrated for their ability to enhance tracks without ever sounding processed. With these plug-ins, you can:
Add silky, open air to vocals and masters.
Shape and tighten the low end using the famous “boost and cut” technique.
Clarify midrange instruments like guitars and pianos without harshness.
Push extreme EQ settings that still sound musical and natural.
Give your tracks that analog warmth — just by running them through.
The three legends of the collection
EQP-1A – The timeless classic
The EQP-1A is the most iconic equalizer in recording history. Its passive design and tube amplification create a smooth, rounded tone that flatters any source.
Its signature trick — boosting and cutting the same low frequency — produces a magical tightening effect that adds depth to kick drums and bass instruments.
MEQ-5 – The midrange sculptor
The MEQ-5 complements the EQP-1A by focusing on the critical midrange. With two boost bands and one dip band, it gives guitars, vocals, and synths the perfect presence in a mix.
Its overlapping filters interact musically, enhancing the “power region” of your track without fighting the rest of the spectrum.
HLF-3C – Vintage control, modern precision
Completing the collection, the HLF-3C introduces 12 dB per-octave high and low-cut filters for vintage-style tonal shaping or creative lo-fi effects.
Perfect for cleaning up unwanted rumble or taming excessive highs, it maintains that unmistakable analog smoothness.
A history that changed recording forever
When Ollie Summerland and Gene Shenk founded Pulse Techniques in 1951, they hand-built every single Pultec unit from a small workshop in New Jersey.
Their craftsmanship quickly became legendary — and their EQs, now considered masterpieces of analog design, remain among the most sought-after vintage units in existence.
Universal Audio has honored that legacy by preserving the sonic DNA of the originals while adapting them for today’s digital workflow.
Artist presets and modern workflow
To showcase the Pultec Collection’s potential, UA enlisted top producers like John Paterno (Steve Gadd, Bonnie Raitt) and Jacknife Lee (U2, Taylor Swift), who contributed exclusive presets for acoustic guitars, drums, and vocals — ready to inspire your next mix.
Conclusion
The Pultec Passive EQ Collection isn’t just a digital replica — it’s a tribute to one of the most musical pieces of studio gear ever created.
Whether you’re shaping a bass line, enhancing vocals, or sweetening your master bus, these plug-ins deliver that unmistakable Pultec magic that simply makes everything sound better.
