Add a Legendary Limiter to your Studio

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

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

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.

Mi compresor favorito

Me encanta como suaviza todo lo que pasa por él, sobre todo lo uso en voces y las suaviza súper bien además por el color que tiene a veces simplemente lo puedes usar para colorear

Musical and Subtle

Love the 175B and 176 compressors for maintaining a rich natural and warm fat sound. I use them primarily on clean guitars and for squishing room mics in a way that just sounds natural. If you're into just wanting to give a little 50's/60's character to instruments that need just a little something special, these are hard to beat.

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.

best of both worlds!

I always thought that the 1176 was my "desert island" compressor, but the 176 has everything I love about the 1176 AND the LA-2A in one unit. How did I go this long without using this?

Time Tested Excellence

These units have stood the test of time for a reason. Pure sonic pleasure. To have these units in software form is magic. UA bring this to us for a fraction of the cost of just one of these. The emulation is superb, and we can use them on multiple tracks simultaneously. Fantastic.

Not a shy comp

UA 175B & 176 Tube compressors do their job in a very effective way. Push forward and saturate the track as expected. Top ogni you want a decisive sound.

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.

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.

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.

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.
