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.

Perfect EQ

This eq is great. The three seperate parts helps keep DSP usage low if you're just after little tweaks. Make this one of your first purchases (all though the legacy pultec is still very nice)

Every session I end up using a couple of Pultec's

The Pultec is my go to eq for guitars, bass and vintage keyboards.
I really like the simple lay out of the controls, and the magic that goes on, once you boost and attenuate the same frequency range at the same time
I already liked the original Pultec plug-ins, but the these new versions are just a little better.

Nailed it!

In comparing this to the original plugin set I wasn't noticing a huge difference on kick, bass, etc... When I put it across the 2bus though it was almost immediate satisfaction. Before adjusting anything I heard and felt that thing that pultec type eq's bring (sheen, weight). UA nailed that. It makes a difference just being in the signal path. Subtle adjustments are really effective and help finish a mix nicely. Great product.

I was a big fan of the legacy pultec. I upgraded the 1176 and LA2A collections a long time ago, but waited on the pultecs because the legacy was just so good. I finally updated the pultecs during UA's must excellent holiday sale and have been loving this version. It does everything the legacys did but smoother and quieter. I recommend upgrading the pultec, but get the 1176 and LA2A collections first (or get the bundle and save a few bucks)

A Fantastic And Quick Alternative EQ

I was looking for the Eq that would pull out the Midrange in a bass track a place it in the forefront. This worked for what I needed it to do. It also works for giving a lift in the high end for vocals and overheads. I went to the presets and tweaked it to fit my mix. Nice.

Pultec for ever

The differences between the old and the new version of this
legendary EQ is amazing!
I've been waiting for too long before upgrading this fantastic plug-in...

Work real good, black round buttons, good – me like.
Cavemen enjoy feeling knobs with mouse-hands, very tactile.
Can't use spear, bad, wreck monitor screen thing.
Me buy again, trade 3 stegosaurs spikes for purchase next plugin.

Best emulation of the Pultec

This is by far the best Pultec emulation I have heard to date. The low end sounds much better on this than my Waves version. I highly recommend this plugin.

Dead easy, gorgeous looking, sweet sounding

I've never worked with a real Pulteq, and quite frankly I never understood why people were raving about this old box. Haven't EQs gotten so much better over the years?

Well, I don't know if it's the ease of use or the character it has but I do see now why it is still so popular. It has become my go-to EQ for guitars and individual drums, even sometimes vocals.
Many times just because it's so dead easy to dial in.

This new version is not all that different sonically from the legacy plug. It does have some more beef low end and some slight improvements, but sadly not enough for me to pay the price.

The GUI is one of the most beautiful UA has put out there and it is also optimised for retina displays which few of the UA plugs are. A+!

Really Great

I lean more to the player/computer geek side of things. So I wanted to take a while with these guys before leaving a review. Having said that, the Passive EQ collection is simply great. They sound great, the presets are very usable and tweaks are easily made with musical results. Again, I don't have tons of experience with the hardware version so I was a little apprehensive. That quickly went away. Well done to all at UA.

They nailed it. Awesome Analog goodness!!! This is how plugins should sound. Silky smooth filters. Brings out the fundamentals very nicely.

A sculpting dream

Love this EQ for it's lack of a bad spot any place. It's pretty much salt to taste anywhere and you can't do anything wrong. Listen to some of my work I've done here galacticpolicy.com

I use it everyday, almost on everything

UAD Plattform ist the Best

This piece of gear must be present in every channel/bus/mix.
The simple act of inserting a pultec with flat settings enhances the sound whatever it be. Nevertheless, if you tweak any parameter, the result is still musical and warm for every sound. I have used it on almost all instruments (vocals, pianos, guitars, drum elements, synths...) and the result is always AAA. Highly recommended.

In my opinion it should be the first set of UA plugs you buy,(then the LA-2 and 1176 collections)...What the UA Pultec does different than other "emulations" is that (like the original)just running audio through it gives a bit of a "lift" to the track...I used to use the Waves versions but not any more..This is solid, dead on, and I use it on literally everything. It's 100% chock full of "tone and vibe"...and worth every cent...and in my experience is about as close to the "original" as can or will ever be had...BUY IT NOW!
