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.

Excellent sounding plugin

Great plugin, very useful presets as well!

Only thing I miss is to touch the knobs and making settings by hearing and feeling - but with my special Midi-Controller it feels ok;)...

Great to have it. And with the satelites I can run a lot of them in my mixes:).
Again and again it is astonishing what it sounds like. Not only an EQ for "technical fixes" - it's "sound and character building" in a musical way - I think.

The sound you get from this makes it hard to resist putting it on everything! Incredibly musical EQ. It's happy being subtle or in your face. Love it!

What's not to love, it's a Pultec! XD

The ever famous boom and fizz. Most people know the pultec trick where you boost 60 hz and attenuate at the same time. When they made them originally they didn't realize the frequencies weren't quite the same, so you actually scooped out low mids just above the low end frequency you were boosting. That of course got us closer to the Fletcher Munson curve we all love so much. This plug in is really something. UAD makes the best. I have the legacy version and eventually want to get the newest one as it sounds a bit more modern, even though I think it's meant to be a newer take on the vintage EQ.

I love this collection of Pultec plugins. Putting the EQP-1A on any track makes it sound better just by passing the sound through, like the tape and summing plugins. And if you really need to change the sound it’s done quickly and easily. It keeps the sound natural and smooth without harshness. Among my favourite and most used plugins. Highly recommended.

Such a difference

I am used to the Waves version and people always told me there was a difference. I was so surprised at how much better it sounds. Waves is very good but this is just perfect

Great sound

Great plug in, it softens the track where you put it, it also works just by inserting it without turning any knobs.

A Flawless emulation of the Pultec EQ. There's only one reason to get this plug-in... ...Character!!!

I was familiar with other Pulteq emulations, but Universal Audio's is much superior. If you put it on a track without any adjustments it feels and makes a difference. I will do great mixing (at least I hope).
