MASTERING EQUALIZER

P440 SWEET SPOT

Never lose a punch. Never alter the original timbre.

P440 is a mastering equalizer designed together with Robb Robinson, a Grammy-winning mastering engineer. It does not model a hardware unit and it does not borrow anyone's curves. It has three stepped bands, shelves whose shape changes with every position, resonant filters, and two circuits of its own. TREMOR works the range below the bass, starting at 7.83 Hz. TIBO tightens the low end without narrowing the stereo image.

Release date to be announced.

The sweet spot, by design.

P440 Sweet Spot is not based on any previous hardware EQ designs or topologies, nor does it copy the curves of any existing EQ. Instead, it is a completely new and liberated design that transcends hardware's physical limitations, resulting in the creation of unique circuits such as TREMOR and TIBO.

The P440 reveals the sweet spots I heard in my ears, imagined in my mind, and felt in my soul.

Ziad Sidawi Audio Equipment Designer

Nothing here is copied.

P440 does not follow a hardware topology and does not reuse an existing EQ's curves. Each stepped frequency, gain and Q was chosen by listening, over many hours of comparison against Robb Robinson's mastering units. The positions are where the sweet spots were found.

Cuts that add punch.

Attenuating a band with P440 usually makes it punchier instead of thinner, and a boost opens the sound without choking the transient. Neither move changes the original timbre, which is why P440 is used on 2-buses, stems and full masters as much as on single tracks.

TREMOR and TIBO.

Two circuits that exist because the design was never tied to a chassis. TREMOR works the infrasonic and sub range starting at 7.83 Hz, the Schumann fundamental. TIBO firms the centre of the low end while the stereo image stays as wide as it was.

Nine circuits, one faceplate.

Every block has its own LED to switch it out, fine-tune sliders next to the stepped knobs, and a shortcut to hear the mix without it: hold Cmd+Option on macOS or Ctrl+Alt on Windows over any control.

TREMOR
INFRASONIC TO BASS, 7.83 TO 90 HZ
A P440 original

A low-frequency band built on Earth's 7.83 Hz fundamental and its Schumann series. The knob sweeps from infrasonic support below 20 Hz, through sub-bass to 60 Hz, into bass to 90 Hz; GAIN sets its intensity. Lock it to the HPF and you can tighten woofers with the filter while TREMOR adds support underneath the mix.

TIBO
TIGHT BOTTOM, SAT, SIDE FILTER
A P440 original

TIBO tightens the low end and firms the centre of the image without altering the stereo picture. SAT adds targeted low-end saturation for grit, girth and presence. Press S and TIBO becomes a mono-maker below the cutoff, filtering out the side information, which is what vinyl and club masters usually need.

BANDS
LOW, MID, HIGH · STEPPED
Proportional and inverse-proportional Q

Three bands with stepped FREQ and GAIN, three proportional-Q shapes per band and an inverse-proportional option set separately for boost and cut. FINE Hz, FINE dB and a Q trim live between the steps. Right-click a FREQ knob for Resonance Hunt: a tight, temporary boost that finds the spot without soloing the band.

SHELVES
LOW SHELF, HIGH SHELF SELECTOR
Each position its own curve

Each low-shelf step is a collage of frequency, slope, gain and curve; the high-shelf selector steps through shapes that dip, step, bend, leap and roll. INV turns a boost into its complementary cut with the shape intact, Shelf Shift bends the curve per position, and FREQ and GAIN fine-tune in between.

HPF · LPF
RESONANT, 2-POLE
The high-pass starts at 7.83 Hz

The HPF starts at Earth's frequency and its RES knob runs from a resonant peak down to a softened 6 dB per octave slope. The LPF does the same at the top, reaching 21 kHz in 44.1 and 48 kHz sessions and 33 kHz above. A dot marks each default, an LED switches each filter out.

SOUL · O2
THE SIGNATURE, AND ITS ENHANCER
0 to 100 percent

SOUL is the sound of the device itself: 100 percent is the full signature, 0 approaches a pristine digital state that still keeps its essence, and the first twenty percent alone hold a universe of variation. O2 only engages within SOUL, subtly separating and sharpening elements. Robb sets SOUL first and then adds O2 inside that contour.

MOD · HW · TX
MODIFIED CIRCUIT, FIVE COLORS, TRANSFORMER
Color, in three switches

MOD switches in an alternate circuit that excites transients and adds weight and punch without clouding or loudness. HW offers five hardware colors, crosstalk, channel deviation and even or odd harmonics, some for image and some for transient density. TX picks one of five transformers from LO to HI: low for the bottom end, high for the bass.

DUAL MONO
STEREO, MID, SIDE, LEFT, RIGHT
One instance, one component

Dual Mono adds the left and right tolerance variance of analog hardware for a naturally wide, dynamic image; TREMOR stays identical on both sides so the foundation holds. The routing switch processes one component per instance with the rest passed through in context, and S solos it, or collapses STEREO to mono.

SCALE · BIAS
MACRO GAIN, DRIVE
Two knobs for the whole curve

SCALE moves the GAIN and fine-tune of all three bands together: clockwise deepens every boost and cut, counterclockwise relaxes them, the middle is 0 percent. BIAS drives or backs off the internal circuitry, from a slightly more aggressive, forward tone to a more relaxed, expansive depth and clarity.

From the mastering desk.

The first word that comes to mind when flipping through the P440 filters is FIRM. Your ear quickly locks onto their boundaries, and you can dial in confidence with or without visual graph representation.

When the P440 is bypassed after dialing in curves and colors, the constructive difference is usually shocking. I treat P440 like an analog EQ with tonal options, and it continues to impress me daily.

Robb Robinson Grammy-winning mastering engineer, from the P440 user guide

Separate attenuation from boost.

I prefer to use two instances of P440. I use the first instance for band attenuation and turn off all other features such as filters, shelves, O2, Tremor, SOUL, and so on. You'll notice that cutting with P440 usually adds a punch to that EQ band! You use the second P440 instance for boosts and other tasks.ZIAD SIDAWI

Find SOUL first, then O2.

There is a ton of variation in the first 20% alone, so pay attention to every click. Once you find a SOUL setting that gives the source a constructive nonlinear shape, you can drive O2 into it for a little harmonic fattening, but this time within the contour of the chosen SOUL flavor. The two work off each other, so a little goes a long way.ROBB ROBINSON

Press Dual Mono.

Dual Mono was the star of the show today. Every time I pressed the dual mono button, the added dimension was constructive and pleasing, without any loss of power or bizarre image manipulations.ROBB ROBINSON

This EQ is so transparent it sometimes seems like it's not working at all, but trust me, it's working! I find the P440 shines in delicate applications...Small adjustments. As others have stated, it is up to the task of master bus duty. Reminds me of Manley's Massive Passive.

Simple and effective equalizer. IIRC it was the first to incorporate the Tremor feature. 3 bands, HPF, LPF, High Shelf and Low Shelf. Now it also has a visualizer for those who want to see the eq curves.
TIBO is for tightening the low end, and can work along with the low end saturation. A bit expensive, but it has received numerous updates through the years.

The EQ points and curves are very musical and forgiving. Even with larger boosts or cuts, it's difficult to make things sound harsh or unnatural.
I boldly state that the P440 encourages experimentation, as it took me more than half a year to fully comprehend its capabilities. The latest addition of the EQ band visualizer is amazing, although I wish it had a spectrum analyzer as well.
 "Sweet Spot" focus: The plugin lives up to its name. There's a certain "magic" to the way the EQ interacts with the audio, making it easy to find pleasing tonal balances.

One of the things I really enjoyed about this piece is that it is very simple to dial in a great sound. It doesn’t feel overwhelming and has just enough control to not be too simple. I’ve used this on vocal, instrument and drum buss to dial the mix in a bit and then I use it while mastering to give the overall mix a little more depth and detail.

C'est plus qu'un EQ, il apporte un beau son analogique, un peu comme un exciteur. Il est propre, neutre ou coloré, c'est au choix. Il apporte des basses fréquences organiques et les courbes sont bien pensées pour le mastering. Maintenant avec l'ajout de la visualisation des courbes, c'est superbe.

It would be easy for some, I suppose, to pass this off as "just another EQ" and an expensive one at that. Now, I'm not a professional audio engineer, just a keen amateur producer/engineer but I can tell this is no ordinary EQ. For a start, Pulsar Modular's exquisitely designed GUIs make me want to use them. The interface is clean and the clearly laid out controls belie the complex functionality and processes happening under the hood. There's a learning curve to the P440 because it's much more than just an EQ but once the fundamentals have been grasped, it's easy to use. As I've said, I'm just an amateur so it's difficult to explain just what it is that sets this apart from many other plugins of the same category. What I do know is that it sprinkles that magic fairy dust on all my mixes and, like pretty much all the other PM plugins I own, gets used on almost every project. That alone makes it worth the investment. The continuous development and improvement of these products and the excellent post sales support makes this and all Ziad's product line excellent value for the money in my opinion.

A couple of months after I started using the P440 I posted a comment about it on Instagram saying I already used it on 90% of my masters. Ziad joked, asking why it wasn't 100%. It's close enough to that now.
Both ITB and analogue mastering starts with this in the processing chain to set the (elevated) tone, and some tightening and clearing. Even just the Transformer options, the HW varieties and Soul (+ more rarely O2) give the music a unique send-off into the rest of the processing. Indispensable.

The p440 eq is a special one. Clean but gives body to the sound. It's certainly not easy to use at first but once you get the hang of it it opens up many possibilities. Don't mistake this with a regular digital eq. Tremor creates a nice cohesion with the ultra low frequencies and the low body of the kick. Tibo adds saturation exactly at the spot you want with the help of the bias knob. The shelves are also helpful in achieving the right amount of heft and sparkle.

Though it is not very easy to use at first, this is the best tone shaper with density, mojo, vitality but cleanness. Add to that, it’s incredible that it could be dealt with exceptionally low CPU usage except for OS/Soul on. Moreover, I like its GUI, however hope it should be get better visibility….
Well their products are certainly expensive but low costs. Want to buy other theirs in near future.

I was mixing an only piano and lead vocal track when I did try the P440. I put it on the master bus comparing with my Chandler plug in, Diamond Eq plug in, Manley Massive eq etc... and with only a few adjustments, the medium of my lead vocal jumped out of the speakers. The sound was so clear and with vibes and color at the same time. I did my master with this EQ and my client (a Female singer) said that it was the best vocal sound I ever made for her (my vocal plug-in chain was the same I did use on the other recordings for her) so I bought P440 immediately and then used it on maybe 20 mastering projects since! Usually on mastering eq I like treble or bass but never both, however, with P440 the low are as good as the mids and highs. P440 sounds exactly like an analog hardware high-end EQ- Clear, wide image, big and precise bottom, etc... A WINNER!

I bought it in the initial period and I must admit that I had to reset my ear and spend some time on several aspects before I fully understood how it worked.
In the end, I think it is an absolutely outstanding and rather unique mastering plugin.
It is difficult for me to explain what it does that is unique but it is like being massaged by a great physiotherapist...! You think you are relaxed but instead, hidden tensions are resolved by the good professional. This is what P440 does to the sound, in my opinion.
I do apologise for the comparison, but I really cannot find any other more appropriate words.

I am reviewing this as a beginner who produces with ITB, not a professional.
I can't say it well, but my first impression is that the p440 has made my music sound like a stew that has been simmering well over several days.

It is pleasant to read the manual and explore the sound by moving the knobs and listening to the changes in the sound, as if my senses are being expanded in a more subtle way. It is a great learning experience.

I got so absorbed in touching the knobs during the demo that the day flew by and I decided to purchase the product. There are so many parameters that I didn't know what to expect. I don't think I will ever be able to understand everything about this EQ, but it is fun just to play with it. I lose track of time.
There is no such thing as an analyzer to visually display the changes in the sound, but I am not an engineer, so it did not bother me, and on the contrary, I felt I was able to pay attention to the changes in the sound.
I don't know if this EQ will be liked by professionals who have to produce a lot in a limited amount of time while maintaining a certain level of quality.

I think it works well with orchestral instrumental VSTs. I feel like I am able to fine tune the piano or orchestra that I have programmed into a rich sound.

I know this may be a luxury request as a beginner, but I have two requests: there is an AB compare button, but I would like to see more of them, and I would also appreciate an Undo and Redo button.

When demoing this EQ before purchasing, I would like you to try it for at least two days while reading the manual.

In Japanese.

今ままではプラグインEQでローエンドに手を加えると、結局デメリットの方が勝ってしまい「何もしないほうがいいな」という結果になることが多かったのですが(特にインサート位置がマスター段に近づくにつれて)、P440では満足のいく出音が得られました。
TREMORとHPF、TIBOで狙った音像が作りやすく、特にTREMORが最高です。
もちろんいじればいじるほどデメリットも出てくるのですが、それが従来のプラグインEQと違ってあまり不快な変化ではなく「これはこれでありかもな」という感触の出音になるのが好印象です。もちろん低域以外も。

BIASノブでヘッドルームの調整と各種オプションをオフにする事でブレのないクリアな、いわいるプラグインらしい挙動にすることも出来ますし、のっぺりしてる音に実機を通した様な奥行き感を付与したい時はMODとSOUL、O2で大体事足ります。

トランスの位相シフトの帯域を選択できるのもありがたいのですが、欲を言うとこれもオフに出来たら最高でした。

最初は見慣れないパラメーターが多くてなんだこれ音いいけど使いにくい…という感想だったのですがマニュアルを読めばやたらとわかりやすい解説が付いているので、一度各種パラメーターの意味を理解してしまえば逆にかなり使いやすいです。

プロでもなく趣味でやっているだけ、かつここ3年位で下がりに下がっったプラグイン市場の価格帯に飼いならされてしまった人間からすると正直かなり高価なので購入に抵抗があったのですが、P440があれば1.2年は追加でプラグインEQ買わなくていいだろうという気持ちと昔はこれくらい普通の値段だったよなって考えて購入しました。でもセール時期まで待ってました。

いいものです。

This EQ has quickly become my favourite for slightly coloured and vibey eq duties. The sound is top class and it has many features that take it beyond eq. I find myself using less compression when this bad boy is in the signal chain. That is a good thing. So far, it is has kept evolving at a phenomenal speed too, getting new features every week. Surely this will come to an end, but it is very reassuring to know the dev is behind his product like no other dev I have yet come across in nearly 30 years of DAW-ing. The learning curve is steep and long. Controls are a bit different than all the other eq plugins, but that is perhaps even a good thing. It forces you to listen more and look at values less. Mixing is not math. I mainly use it on busses and masters. Sometimes I use it on single tracks as well. Sure, it is a mastering eq, but for tracks that just need a light touch, why not use the best? :D

What a great eq this is. It just never sounds bad what ever you throw at it. I was an early leaper on Sweet Spot and the way this thing has developed is something else. Just like P11Abyss and P42 Climax this thing has just got better over time. Bypass is fatal using this because it sounds so good. Great CPU usage is always welcome and Sweet Spot handles that very well. It just never sounds bad and i like what i hear.

When I set up P440 on a master, it felt subtle - I played around for a while and didn't feel like I had adjusted things much. When I bypassed it, I was blown away by how much was lost.

The P440 is not just an eq. You have saturators that come with the transformers and HW emulations. So yes, this is an eq, but much more if you use all the options, and all sound more than right, are greats.

Thanks to the P440 I could take off a few plugins in the chain, now is a lot more efficience. Also, I suggest to try do the summing with the P440, work really nice.

I used it as a mastering EQ in WaveLab11.
I felt unprecedented smoothness and transparency, and a generous amplification stage that does not easily collapse even when the gain is significantly increased. There are EQs from other companies that make it easy to understand and capture changes at individual points, but in such cases, the total nuance may not be preserved, and I feel that the P440 has some magic that does not destroy the overall image.

This EQ confused me at first. I tried it and was wondering what it was doing. opened in plugin doctor to get a feel for where the bands were when i was using it.

After I learned the basic settings... I started doing mixes with this, p42 and p11. For one of the first times my mixes feel open yet focused. There is balance in my sound.

I think in the past I would go hard on the eq resulting in boxed in sound. This plugin encourages different moves and the end result doesn't put it in a specific box. Even if you try... it wants you to win and you can't go wrong with any setting. I don't get it but in the end the mixes speak for themselves.

It's alive! The sound of P440 will blow you away. Close your eyes and listen and you won't believe what you're hearing isn't hardware. When you use it you'll realise it's far more flexible than other eq's you may have used in the past. P440 - This is the Future!

What a special and wonderful organic sounding EQ this is and I will happily pay the price for this. It's here to stay on my mixbus and beats the ones I previously used. Thanks for superb coding. Top stuff!

I have so many EQ plugins and it was hard to believe that between them all something was still missing.
But there is something so natural, warm and organic about the P440 which none of my other EQ’s have. Rather than compromise the sound it enhances it.
One of my best tests for EQ is on acoustic guitar. It has such a delicate and nuanced sound. Most EQ’s mess with the subtleties and transients, but P440 can improve them, making them even more magical.
P440 is a truly innovative software EQ.

I am, I think, a rare individual who does not care if a digital device sounds 'analog' or not. I just want it to sound good. Or better, great. What I get with P440 is better than that. It sounds phenomenal. And there really isn't much more to say than that.

This thing lives and breathes. And it has given my music a little more life and breath. Love it. Clarity - gloss - precision.

Is it worth the money????

Is your music?

This is the most musical, truly beneficial-to-source digital equaliser I have used to date.
It works perfectly in any production context including the critical stage of mastering.
Congratulations on making a new classic!

There's such a delightful finesse to P440's soundprint, it won't leave my mastering chain anytime soon. The sound is alive and elegant no matter how you set it. The lack of visual cues is super refreshing, it forces you (well, it faces me) to listen to the bands interacting. Finally, I'm fascinated by its flexibility despite the seemingly limited set of parameters. A stunning tour de force.
Stellar, stellar EQ : bravo ! It deserves all the superlatives.
