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.

Unmatched depth and clarity

I couldn’t believe the sonic differences I heard from my synthesizers after these compressors were applied. Absolutely incredible hands down incredible

Received the native versions for free!!!!!

Someone in the comments mentioned that it’s similar to having the 1176 & LA-2A combo!!!! I must say that I definitely agree with him whole heartedly! I received them free in the UA connect app & now I don’t mix without them!

U 175B

$89 I bought in the promotion five minutes before midnight and the other day when I got up, they charged me $150
There is no respect for customers, that’s not fair

Very nice sounding!

This is a real gem, smooth, silky, analog - and it can sound really thick and nasty, too. A good as it can be.

UA 175B & 176 Tube Compressor Collection

Having bought the 1176 collection, I was a bit sceptical of these, but the 176 is now a permanent fixture in my vocal chain. it's quite different to the 1176 and SO FAT! I'm trying my best not to use it on everything - because it sounds great ON everything. The 175B is my 'go to' Hammond compressor and it's great on guitars too, love it!

Two total winners for me

A must have comp

Warm, Full Tone

This is a great collection. The 175B has become a go-to on my vocal chain. It creates such a warm, fat tone and makes the vocal stand out.

Great sounding comp

I mainly bought this comp for tracking vocals. It has so much characther but can be gentle. My main comp for vocal tracking. in the mix I will hit vocals a bit harder with an 1176 maybe a la2a. This comp has instant vibe for sure.

UA 175B & 176 Tube Compressor Collection

We had to wait a long time for these two beauties, they're finally here (UAD original) and THANK YOU for the DRY/WET control for parallel compression and for the little HEADROOM screw :-)
