EQ550 and EQ550b by RRS, OOO
EQ550
https://apps.apple.com/app/id1507132030
Description:
• EQ550 Standalone application — free.
• EQ550 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the EQ550 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of EQ550 AUv3 plug-in comes as In-App Purchase.
The EQ550 faithfully captures the punch, low-frequency transparency, and ultra-tight imaging of iconic American EQs of the late 1960’s.
Making use of Proportional Q intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings without the need for additional bandwidth controls. This unique feature minimizes the «phase-shift» sound found in many equalizers.
Features:
• Standalone and AUv3 plug-in;
• Precise port of Rack Extensions plug-in;
• 3 bands of classic American equalization;
• Each band offers 7 selected frequency centers;
• Maximum 12 dB of boost/cut per band;
• EQ Band 1 and 3 offer shelf/peak switching;
• Proportional Q narrows filter Q at extremes;
• Stereo (Mono), Mid or Side EQ modes.
The EQ550 provides reciprocal equalization at 21 points in 5 steps of boost to a maximum of 12dB of gain at each point. The twenty one equalization points are divided into three overlapping ranges. The high and low frequency ranges are individually selectable as either peaking or shelving, and a band-pass filter may be inserted independently of all other selected equalization settings. Frequency ranges and boost/cut are selected by switches, and a pushbutton «IN» switch allows the EQ to be silently introduced to the signal path. A small toggle switch is used to insert the band-pass filter into the EQ550.
The EQ550 extends the features of the original hardware and joins the flexibility of the digital world to the character of the analog processing. Allows you to choose between equalizer modes (Stereo, Mid, Side) and remove analogue saturation from the processing circuit to deliver pure digital sound.
To use EQ550 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — EQ550 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
EQ550b
https://apps.apple.com/app/id1507176549
Description:
• EQ550b Standalone application — free.
• EQ550b AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the EQ550b AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of EQ550b AUv3 plug-in comes as In-App Purchase.
Based on Classic American EQ from the late '60s, the EQ550b is a continuation of the EQ that played a major role in the history of music recording, but with an additional filter band and several new frequencies. With a surprisingly wide range of tonal variations, the EQ550b is an invaluable and professional audio tool with great flexibility and excellent sonic ability.
Features:
• Standalone and AUv3 plug-in;
• Precise port of Rack Extensions plug-in;
• Modeled vintage EQ;
• Four bands of classic American equalization;
• Each band offers seven selected frequency centers;
• 12 dB of boost/cut per band;
• EQ band 1 and 4 offer shelf/peak switching;
• Proportional Q narrows filter Q at extremes;
• Stereo (Mono), Mid or Side EQ modes.
Rather than offer a huge assortment of complex features, the EQ550b provides exactly the right number of controls. Its four EQ bands are overlapped significantly to aid in dual roles as problem solver and sweetening device with each band offering seven switchable filter frequencies that span four-to-five octaves. These frequencies, purposely selected to be musical rather than numeric.

Comments
Sounds great. Maybe better then the other two eq from the same dev.
Their eqs sound fantastic!
So eq a was a trident emulation while eq 550, 550b and 560 seems like api emulations, right?
So what’s the difference between 550 and 550b... I’m thick. Thanks
An added eq band.
Goodman I just bought the 550 and now I see the 550b with an eq band more😂😂😂
Yes, that’s right. The first two sound really good. I’ll probably pony up for the 550 B. Wish they would do the Harrison EQ...
I have fabfilter, toneboosters, and other EQs (though I tend to use only the two mentioned). Would there be any point in grabbing this new EQ?
DDMF only one you’ll need! That’s all I’ve got for eq. Pricey but!
I think so. These add a distinct color to to the sound, but lack the flexibility. Personally, I’d get GoToEQ by Klevgrand before I got these, but I use the Trident one (EQ A) a fair amount.
I do wish there was a law that every software EQ had to include a visualizer; it’s so incredibly helpful, even if one does listen with ears and not eyes.
Question for you @audio_DT: do you have a logic behind when you use Toneboosters vs FabFilter? I have them both, but so far it seems like they bring many of the same strengths (i.e. transparency and near-infinite flexibility) to the table.
@mulletsaison I have both Fabfilter and ToneBoosters too. My use case CPU allocation. Heavier projects with a lot of synths and FX benefit from lower CPU of ToneBoosters but lighter ones I use Fabfilter first.
Might demo these but don't think I need them either.
Cool. That makes a lot of sense. These are really nice EQs, definitely worth a demo because the use case is different for sure. These add warmth and girth, and are pretty cheap. And if you don’t have GoTo, I’d go get that.
Bought this today, the RRS 550b with the extra bandwidth control based on the API Audio 550b. I wasn’t planning to as I already have a lot of RRS stuff, but I d/l the demo and put it on my mix/synth/drums. Wow, just love how this eq sounds, brings out details and tame things when needed quickly. RRS just never disappoints, high quality for low prices. Check it out, free to try https://apps.apple.com/nl/app/eq550b/id1507176549
I agree ..RRS plugins are fantastic and many of them are my go-to plugins
Awesome that you have a demo for all their stuff. Why is it so hard to implement for anyone else? Developers, look at this!!
Would love to see an API 2500 emu
