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.

Pultec Passive EQ Collection

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.

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.

Pultec Magic

One word.....outstanding!!! Mixes sound warm and fatter than ever, thanks UA!

Yes, the EQP-1A is now sounding even more silk in the hi-end, good job. However it would be nice to have a newEQP-1A + MEQ-5 combo in one plugin instead of inserting two plugins EQP-1A + MEQ-5 to save latency in your system.

The only EQ's you really need.

The EQP-1A and the MEQ-5 have all the harmonics and character, I need, a touch of 3K and a little less of 200 from the MEQ-5 makes all lead singers, or soloists to come up front and present.
A touch of broad 30Hz tweak, some boost and a little att, and the same at 8K and then A/B listen, it is amazing.
A decent Buscompressor UAD 4K or P-Bus Comp is my favorites, before the Pultecs and then the Cambridge for Highpass at 20-30 with a sharp curve, and last the P-Limiter, and you can do masterpieces.
Always try with the pultec's first it 99.9% solves any situation.

Way Over Expectations!!!

Pultec Passive is always my first choice to eq tracks, period!
It works great with pretty much any instrument/vocals and it makes them sounds better instantly.
What this plugin does is absolutely incredible and over expectations.
I always hear people saying: Analog Sound, etc... Yea, but that's not what I'm always looking for, right?! And this one has much more to offer! You actually have to use it to believe.
No idea how close this plugin is to its original gear, since I never had a chance to work on hardware version, but I can tell this software gives me everything I need to make my tracks powerful and cutting thru.
This is my ultimate tool to make my productions in the box sounding just the way I want without a hustle.

The Mother of All Pultec Plug-ins

Arguably, the greatest thing about the hardware Pultec is its ability to inform your music simply by passing your signal through it. If I was working in a studio that had an EQP-1, I made sure to pass tracks I was recording through it just cause it sounded so darn good. I know of scores of studio-rat buddies who have used that same trick. There is no other plug-in out there that has got that sound of the entire hardware Pultec chain of circuitry, including the essential effect of its amp stages, an aspect of this particular emulation that is unsurpassed in all the other Pultec models out there. Like all UAD plugs, this makes me feel like I own the real thing- for a fraction of the price and no maintenance! You did it again, Folks!

UA does it again!

“The UA Pultec Passive EQ is the best reproduction of the original unit currently available on the market, I know this because I have the actual beast in my rack, and I own all the other plug-ins that try to emulate it. 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.”

New Pultec Passive Eq Collection

I purchased and I am very pleased with the purchase. Sounds amazing and provide needed !
Thanks a lot Universal Audio ;)

Legacy Pultecs sounded good, but these ... !

I was Mastering a record in Logic and I had the Legacy Pultecs on virtually all the tracks. Exactly amidst this project the Pultec Collection was released and I gave it a try. The material was very dense and rich in harmonics, so the color and effect of these plug-ins were all evident straight away!
The legacy sounded good, but next to these, they sound candy-like! Amazing
