Astonishingly accurate recreations
of the “must-have” classic EQs.

Building on a decade of the world’s most intensive modeling research, UA has recreated the famed Pultec EQ experience as plug-ins – ones that are nearly indistinguishable from the original analog hardware.

The Pultec Passive EQ Plug-In Collection for UAD-2 and Apollo hardware includes the ultimate plug-in emulations of Pulse Techniques’ original passive EQs. With painstakingly modeled amplifier sections now onboard, the Pultec EQ Collection "breathes" like the original hardware.

now you can:

Use Pultec's three most popular studio EQs on individual tracks or busses

Provide the same Pultec analog “magic” for your tracks, making them sound better just by passing through

Push the Pultec's fully modeled transformer and tube-based amplifier sections

Make difficult-to-isolate instruments and vocals breathtakingly clear without affecting neighboring frequencies

Dial up extreme levels of EQ boost while staying natural and musical

Give that signature airy, smooth-as-silk vintage tone to your master channel

The Pultec Story

The Pultec Story

When Ollie Summerland and Gene Shenk hand-crafted the first Pulse Techniques passive program equalizer in 1951, they had no idea they were transforming an industry. But like a Stradivarius, their little garage-built, made-to-order designs have been copied by nearly every EQ-maker for decades, and their early EQP-1A's still bring thousands on the used market — if you’re lucky enough to find one.

Legendary Pultec Depth and Clarity

Legendary Pultec Depth and Clarity

Going far beyond UA’s original standard-defining Pultec plug-ins, the EQP-1A faithfully models the overbuilt transformers and complex tube amplifiers of the original hardware. Simply running a full mix or single instrument through it imbues the track with the legendary Pultec analog magic. And, with these new plug-ins, you can actually hear the Pultec's amplifier overload effects — just as you would with the hardware — unleashing a bounty of sublime results.

The Signature Effect on Low End

The Signature Effect on Low End

The Pultec EQP-1A’s signature effect, unintended by its designers, is its ability to seemingly boost and cut the same frequency simultaneously. In reality, the filters actually alter adjacent frequencies, but the naturally interactive resonant dip has an amazing boosting and tightening effect — especially on bass guitar and kick drums.

Shaping Your Mids: The MEQ-5

Shaping Your Mids: The MEQ-5

The MEQ-5 Mid-Range Equalizer is the richly colorful tube-amplified companion to the EQP-1A. With two bands of midrange boost and one band of midrange dip, the MEQ-5 gets the very best out of the ”power region” where guitars and vocals can make or break a mix. The unique band overlap and filter interaction unleash the vibrancy of these instruments in the track – without fighting your overall mix.

Tame The Highs: The HLF-3C

Tame The Highs: The HLF-3C

The never-before-available HLF-3C completes the Pultec Passive EQ Collection. This new plug-in adds 12 dB per octave low and high cut filters, for broad retro-tonal sculpting or bygone-era special effects. You can easily subtract the unnecessary frequencies in any instrument and sub-group so they stay wonderfully musical in the mix.

Very Happy

This plugin sounds big and three dimensional. Going between the new Pultec Collection and the old Pultec plugin really shows how far they've come. Good job UAD!

Next Generation Pultec With Air And Dirt

I do not regret updating from the legacy plugin to the new Pultec ... it is a great EQ for Rock'n'Roll productions. The newly modeled tube characteristics make the difference: Now the Pultec collection has more "air" and "dirt" and "balls" and what you can call it - however, it also consumes more DSP power!

Huge different

Great upgrading.

Low: more deep, more punch, larger, silk smooth, analog hardware sounding. old plugin sound soft, dark, small, digital software like.

Mid: Total different, UA you should back my $79. always using Helios 69 for mid freq, now 69 is out my fx rack, replace by new Pultec. large, powerful, but right position, no "in your face" feeling.

Hi: Pultec haven't "open air" sound like API 550, this is original hardware different. old plugin hi-freq have "squeeze" sounding, now gone.

Filter: Alway using Cambridge eq for filter, now replace by new Pultec. more nature, more analog like.

Old Pultec is a great EQ for lo-freq, no one can beat it in lo-freq. but now UA killed it by himself. UA you are a winner who conquered yourself!

The Real Deal

To my ears this Pultec sounds like the real thing. I love it as I do all my UA plugins.
As stupid as this sounds, I wouldn't bother with the hardware ones. Get pretty damned
close with a few tweaks. Hardware Shmardware!!!

Rski Pultec

Many years ago I was informed from a friend the Pultec EQ are a must have, during a mastering mix down, although difficult to obtain

Enter the digital age, the first generation UAD2 Pultec was a welcome addition, when I was a proud owner 2010

The newer on is ever so good, audition wise, hard to express in words.

The HLF 3C is a welcome master buss audition, it has a unique character of attenuating the bottom of a mix, that plug in is one of my go to effects now.

I like the concept of three separate plug ins, very cool

incredible!! another milestone

The pulteq eqs always have been the plugins i use on many channels on my mixes,, on guitars, on drums, vocals, orchestration, you name it.
i love how the new version updated sounds, the high-end seems to be much smoother and more natural. which is a good and a bad thing
especially if you want to have more of an aggressive sound, the new version doesnt sound as aggressive anymore, but i still use the old now called legacy plugin on those parts.
hopefully they newer gonna discontinue the legacy version!

crystal clear

Love the high-pass filter and I use it on drums a lot. It just gets bigger when you put it on. Also, some of the guide vocals tracked in my bedroom with my crappy $100 mic eventually stay on the final versions of the songs because of this eq. Definitely worth the buck!

more accurate than ever

I've been using legacy Pultec Pro for more than 10 years. I still remember when I used it for the first time. It was the very first plug-in I could hear the difference even when all the knobs set to flat. That was the moment I decided to start mixing without big analog console.
Now this new version has made me smile again. I've just used this for the mastering of a sound scape artist and his response was "Wow, what you've done? What did you use?"
Actually I didn't need to turn any knobs much. Just going through this plug in makes a big difference like the real one. I can say this is competitive to that blue hardware.

Used extensively mixing a new single

Compared to the old UAD Pultec,
this new beast really shines on almost every track.
Vocals, snares, bass, and drum buss...
Whenever I put this plugin in tho the chain, the sound stands out!
It's a little bit CPU-intensive, though.

Pultecs are Cool

I have many different Pultec style plugins and they are all different but good in there own way. There is something about this one that's very different from the rest . It seem much more tube like . And the Hi /Lo cut module is way useful for me , I never got the chance to use a real vintage Pultec . But compared to all my pultec style plugins This one has a definite Tube vibe .

THE boost EQ

I don't really care if this collection exactly replicates the hardware or not, what I am impressed by is the sound...this is one of the few EQs that I will use to boost signals. It is sweet, musical and, well, organic sounding. The legacy Pultecs were good, this update is GREAT. You can get ugly or be subtle, and it still sounds delicious! Thanks UA! After 80 albums or so, it is great to still find gems like this for my production workflow.

victim or victor

took advantage of the demo and suddenly began to use new Pultec so often that thought, "I am a victim or victor" .Pultec Passive EQ Collection damn good,the high frequencies are adequate, even at very high power levels

I have used many other UA EQ's for my drum buss. However, the Pultec alows me to carve out a sound that is like no other. Pretty much this will ALWAYS be used. Thanks UA!

Great Upgrade

The fact that I can add this plugin to my track without making any adjustments and hear a harmonic and tone improvement speaks volumes to the carefully crafted, flawless reproduction of the original unit. The Legacy Pultec collection was my favorite Pultec emulation out on the market. However, that's all changed now. The Passive EQ collection certainly surpasses it. Thanks UAD Team.
