Get the hit-making color and tone of API's iconic 212L preamp.

From Fleetwood Mac’s classic, Rumours to Radiohead's In Rainbows, API preamps have shaped hit albums with stunning punch, presence, and color for over 50 years.

Now, you can easily add that same clarity, character, and musically complex tone of this proven, hit‑making mic preamplifier in a simple Unison‑equipped plug‑in, perfect for Apollo owners.

Now You Can:

Get the world’s only authentic plug-in emulation of the legendary Class-A, API 212L mic preamp, with added features from API’s flagship Vision console

Record "through" the legendary API preamp in real time using Apollo interfaces, with low DSP use

Easily color your tracks with musical punch, clarity, and character with an unequaled emulation of complex, nonlinear circuit behaviors

Control Apollo mic preamp gain staging and impedance directly from the API Preamp plug-in via Unison technology

Capturing a Legend with Unison

Capturing a Legend with Unison

The classic API 212L preamp's forward attitude, low‑end punch, and detailed‑yet‑warm high end is famous for giving vocals, drums, and more a satisfying tone with rich character. Harnessing UA's groundbreaking Unison technology, the API Preamp plug‑in is the only complete emulation of API's hallowed preamp circuit, giving you the vintage hardware’s gain staging “sweet spots,” and nonlinear circuit behaviors. The secret is Unison’s bi‑directional control and communication from the API Preamp plug‑in to the mic preamps in Apollo interfaces.

Give Your Tracks the Sound of Legendary Albums

Like the original sought-after hardware, the API Preamp plug‑in adds characteristic punch and musical definition. Plus, you get the same features found in API's flagship Vision Console, including a Mic/Line switch, dedicated cut filter, and ‑6 dB Line pad. Simply drop the API Preamp into the Unison slot of Apollo's Console software or LUNA channel strip to add instant character to vocals, acoustic guitars, drums, and more with the hit‑making tone that can only come from API.

Add Punch and Character to Any Source

Of course, the API Preamp plug‑in isn’t just for Apollo interface owners. UAD hardware owners can harness the color of the API Preamp plug‑in for mixing and tone shaping — without ever leaving the box.

Great for distorted input

I recorded some moog effects with this plug in as insert input in the UA Console, and it blowed my mind. Awesome!!

Been waiting for something like this, a fantastic companion to the Neve Preamp and the 610 plugins.

For years I was hoping they would make this plugin, detached from the bulky Vision channel strip I do not like or use. And here it is, at last! Spot on modeling, sounds legit, doesn't burn up a ton of dsp. Highly recommended for everything except the mix buss.

Small and easy but powerful

Almost uses no dsp but sounds as good as the API Vision Channel Strip! I love it as much than the Channel Strip because you don’t have to think too much or cut a part of the big version. Sometimes less is better!

I've owned UAD since V1 - my first 'review' API Preamp

Wow, harmonics break up ever so nice. I don't record anything with it, but use it on Synth VST and Drums. Perhaps just anywhere. Luvleh!
