The World’s Most Accurate Emulations of API 500 Series EQs — Perfect for Mixing Guitar and Drums.

API’s classic 550A and 560 Series EQs left their indelible stamp on the legendary recordings of the ‘60s and ‘70s, and their popularity has exploded in the decades since. The 500 Series’ innovative modular design has become an industry standard, and Saul Walker’s vintage API EQ modules remain sought-after treasures by owners of studios both large and small. Today, Universal Audio brings you the definitive sound of the API 550A and 560 EQs as UAD plug-ins, faithfully capturing the characteristic filter shapes, complex band interactions, and unique filter amp distortion that until now only the genuine hardware could provide.

Painstakingly modeled on pristine early-1970s units provided to Universal Audio by Ross Hogarth and Capitol Studios, both the 550A and 560 plug-ins deliver API’s legendary powerful punch, low-frequency transparency, and ultra-tight imaging — with all the flavor and character of their hardware counterparts.

Notably, both the 550A and 560 EQ plug-ins offer stunningly accurate modeling of API’s custom 2520 op-amp and output transformer — widely credited with creating the “API sound.”  With its one-of-a-kind filter shaping, clipping behavior, and tight, punchy bottom end, the UAD API 500 Series EQ plug-ins are a must-have tool, especially for mixing guitar, bass and drums.

Watch the overview video.

History
Formed in 1968 by Saul Walker and Lou Lindauer, API (Automated Processes, Inc.) quickly became known with its innovative modular approach to equipment manufacturing. Their unique consoles and components — especially the 2520 op-amp — have long been prized among audio professionals for their extraordinary headroom and sonic character.
 
Introduced in 1971, the 550A was the standard channel EQ module on API’s first consoles. Its sonic quality quickly reached legendary status, and the 550A and 560 modules soon gained new popularity in custom designed consoles and the personal “lunchbox” racks of audio pros. Such is the demand for these units that API finally resumed production after several decades.

550A Parametric EQ
The 550A gives you three overlapping bands of parametric EQ at 15 points with up to ±12 dB of gain, controlled by three dual-ganged rotary switches. The HF and LF bands feature individually selectable peaking or shelving modes, plus an independent 50 Hz to 15 kHz band-pass filter. It’s the perfect secret weapon for helping drums and guitars stand out in the mix.

560 Graphic EQ
The 560 offers ten bands of graphic EQ, making it an ideal tool 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.

    Peter Katis

    (The National, Interpol, Tokyo Police Club)

  • Jeff Juliano

    (John Mayer, Shinedown, Train)

    "I've been a die hard API fan for 20 years. UA knocked this one out of the park. Twice."

    Eric Persing

    Spectrasonics

    Miles Walker

    (Rihanna, Katy Perry, Wiz Khalifa)

    “With these the new [UAD API 500 Series EQ] plug-ins, I've got all the great sound I love from the original 500 EQs, and not limited to only a few channels of it! Amazing model, down to the color it puts on even in bypass mode. I'm fully amazed.”

    The Glitch Mob

    "The new [UAD API 500 Series EQ Collection] has the best graphic EQ plug-in out there. Hands down no contest."

    Darrell Thorp

    (Beck, Radiohead, Charlotte Gainsbourg)

  • Jeff Balding

    J.J. Blair

    not bad at all!
    by H. Hamilton (Monday 26 August, 2013)

    These eq plugins do a very musical job. Just a little sweetening is all it sometimes takes and these do it most nicely. They can also make some very agressive mods. I like the 560 a lot on guitar. Just a little extra high end a bit out of the middle and suddenly its the sound I hear in my head (whic … Read More

    fantastic lo end !
    by S. Simmich (Friday 12 July, 2013)

    As an owner of the Waves API bundle I had to think more than twice before buying the same emulation again. After doing some mixes with the demos I had no other choice... These plugins absolutely shine on drums, my personal favourite is the 560 for kick and snare and 550 for drumbus and bass. … Read More

    560: My favourite UAD EQ
    by A. Theakston (Wednesday 8 May, 2013)

    Couldn't really be more impressed with the 560 EQ - as others have mentioned, it's completely transformative. You can put sweet air back into anything, like a subtle little swiss army knife; but you can also do big broadsword cuts and boosts - and it just plain sounds good doing it. A major usabi … Read More
