The world’s most accurate
emulations of API’s legendary EQs.

The API 500 Series EQ Plug-In Collection for UAD-2 hardware and Apollo interfaces faithfully captures the punch, low-frequency transparency, and ultra-tight imaging of API’s iconic 550A and 560 Series EQs.

With unique filter shapes, complex band interactions, and musical filter amp distortions, the 550A and 560 Series EQs left an indelible stamp on legendary recordings of the ’60s and ’70s. Painstakingly modeled on pristine early-’70s units provided by Ross Hogarth and Capitol Studios, the API® 500 Series EQ Collection gives you stunningly accurate, end-to-end modeling of these revered EQs.

Now You Can:

Track and mix with full-circuit emulations of API’s iconic 550A and 560A EQs

Harness API’s musical filter amp distortions and musical clipping behaviors

Use API’s proprietary “Proportional Q” for more precise control over your sources

Mix with artist presets from Ross Hogarth (Van Halen, Mötley Crüe), Darrell Thorp (Beck, Radiohead), and Vance Powell (Jack White, Kings of Leon)

550A Parametric EQ

550A Parametric EQ

Introduced in 1971, the 550A was the standard channel EQ module on API's first consoles.Its three overlapping bands of parametric EQ, independent 50 Hz to 15 kHz band-pass filter, and individually selectable peaking or shelving modes make it the perfect tool for getting drums and guitars to stand out in the mix.

560 Graphic EQ

560 Graphic EQ

With ten bands of graphic EQ, the 560 EQ is ideal for shaping your mix with surgical precision. API’s proprietary “Proportional Q” intuitively widens bandwidth at lower boost/cut levels and narrows it at higher levels, giving you more musical control over precise bands of your mix.

Perfect for rock music

I find the graphic eq to be my go to when shaping both drums and even vocals. It's a very up front eq. While The 550a is a amazing tone shaping unit for vocals and acoustic guitars

Thanking myself for this one

Impulse bought this for a session expecting never to use them again and boy was i wrong. By far the closest plugin around when it comes to standing up vs the hardware. The 550A is wonderful on claps, snares, synths, etc while the 560 always swoops in to save the day when youre in need of a precise eq but want to keep things sounding natural. High end too busy? Throw a 560 on your cymbals and solo it with the lead vocal. Flip through all your monitors in mono and you'll come out the other end with some clean results

I use this to create separation between tracks and trust me, it works like butter on toasted bread at morning time.

Guitar Players... Buy This!!!!

There's nothing like an API 500 on a distorted rhythm guitar. If you don't own this one, you're severely missing out. The gain staging is weird (I guess all analog gain staging kind of is), but this definitely sounds like the hardware gear would sound, and adds some nice, silky harmonics.

clean and clear and under control

For real though, I can push the mids of vocals with the 550A more without them getting harsh. 560 is on steroids compared to competitor emulations. Definitely a solid tool in the kit.

I can't believe I waited this long

I have a ton of Neve colors in my setup (pres, compressors, and of course Neve summing in Luna), but I just got the API EQs and can't believe I waited this long. They bring a completely fresh and easy to dial in color to my tracks and mixes. Super easy to use and introduce a ton of character and enhancement to all my tracks. Having a blast with the 550A on my channels in Luna, with the 2500 on busses and master, and of course the newly introduced API summing - it makes for a totally powerful mix that has come alive with tons of character. Highly recommended!

I’ll often put the 550A across every channel. I’ve never been disappointed.
