TAKE A LISTEN
Add a Legendary Limiter to your Studio
Introduced in the early 1960s — and used on thousands of seminal records — the UA 175B and 176 were the first compressors purpose-built for studio recording and mixing music, giving engineers groundbreaking fast attack time and independently variable Attack and Release controls.
Experience Deep Tube Sonics
Based on a pair of UA's 1960s golden units, the UA 175B and 176 Tube Compressor Collection gives you all the ultra-musical harmonics and colorful saturation of these original units — down to their magical feedback compression circuit — giving you softer compression at lower input levels and harder, nearly brickwall limiting at higher levels.
Get the Rich Sound of an All‑Around Champ
Perfect for vocals, drums, guitars, and more, the UA 175B and 176 plug‑ins give you all the character and juice of the originals — indistinguishable from the target hardware in blind listening tests. Easily add depth to room mics or a drum bus, give your guitars definition, park a bass in a mix, and inject vocals with energy. You can even turn off the compression and use the 175B/176 plug-ins as a "tone box," lending rich tube textures galore.

Great Saturating Compressor
Just as the title says, the tube warmth and saturation can really be heard with these guys. I really never hear anybody say they're using one of these compressors, it seems slept on. It's kind of a mix of all the popular studio compressors. They're good, if that's what you're asking for.

Love it on Rock Drums!
Love it on my Rock drums , it brings the room in a very nice way. Use it a lot on bass too.
C. Davis
Unique
This thing has a pretty unique sonic signature. The mid range is just *tasty*. There are places where the LA2A works better, places where the Fairchild works better, and places where the DBX 160 works better. But on my particular scratch old, this thing is the bomb. Definitely do the trial and see if it fits what you’re trying to do. I’m loving it.
S. Jones
Do not pass over this compressor.
I think we all read reviews and compare the list of awesome UAD compressor plugins. All the recording standard 1176 and LA2A style compressors that are my go-to compressor plugins. I have picked up several others but always skipped over the 175B and the 176 because I figured it can't be as good as the 1176. I decided to finally purchase and experiment and boy was I wrong. I am extremely pleased with the goodness these compressors bring to my ears. There is power and a nice sonic tone that hear compared to the other compressors. I will definitely be using these more often. *** WARNING: If you buy this compressor plugin first you may not like other compressor plugins as much ***

Vintage tube at its best
Love this two, Ghe 175B is just amazing, explosive warmth and saturation.
M. Saxon
Versatile and full sounding
I love how subtle these compressors are. The word "warm" is used a lot but they have some nice saturation. I'm still experimenting but so far I'm digging using the 176 on the bass and electric gtrs. UA continues to bring high quality plugins and my collection is slowly growing.

très bon compresseur, aussi bien que l'original
J'utilise ce compresseur au mixage comme au mastering.
J'aime beaucoup la manière dont il me gonfle mon son, et la prise de l'espace sonores qu'il m'apporte.
Selon ce que je veux avoir comme résultats, il peut avoir un rendu transparent ( pour mes masters ) ou assez agressif ( sur les mixages, traitements des voix , ou des drums).
Un incontournable a mon humble avis.R. Gonzalez Yanel
Color
Me ha gustado tanto en bajos como en voces y baterías. En paralelo suena brutal también.
