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.

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.

I dislike grafic EQs but sound good nevertheless.
It forces me to by the Hardware...

API At Its Finest

These are top-of-the-food-chain emulations. For a real treat, try the 560 on guitars. The EQ is perfect for both electric and acoustic.

API sweetness.

I put this plug on (560) on nearly everything to sound like all my tracks are going through an API board!

560 for the BASS.

I love to use 560 on my synthbass, I can do magic with this.

Punchy and musical

All it took for me to purchase from demo mode was to put the 550 ‘drum room’ preset on a Superior Drummer track. I couldn’t believe the difference it made in all the right ways. It really opened the track up, made the top shine, mids clear, and the bottom punchy and clean.

The EQ of EQs

This EQ has so much clarity and energy. My go to for pretty much everything.

It’s easy and simple!!

とても良い品物です!
僕はミキシングの時によく使います。前段でコンプやEQをかけ全体のバランスを見る時、どうしてもある一定の部分だけの帯域を下げたい時が必ずあります。そんな時これはとても便利です。
単体のトラックにかけるのもよし。アウトプットにかけ全体のサウンドにフィルターをかけるのもよし。
とにかく痒いところに手が届く優れものです!

Best 500 Series EQ

My favorite 500 series eq, I mainly use the 550a for vocals and drums. 560 for piano and pad sounds. the controls work very strong, but still very clean and transparent sound, really amazing

Just wow

I have the Vision Strip plugin and still find myself using the 560. I find they are both similar in sound quality but the 560 has a cleaner more rounded and magic to it. Of course that is because it has 11 bands but I really think UAD smashed it on this and all other API things. After being introduced to API plugins, I have to say, API will be the EQs I turn to the most.

It's not just an EQ. It' saturator!

Yes, this is very colored EQ and it was the main reason I bought it after testing. Any small changes to the chosen frequency not only adds or reduces it but it also adds so many color to your sound. So I started to use it instead of distortion or saturation plugins in some cases, and this is what it was bought for.
