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.

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.

Color

Me ha gustado tanto en bajos como en voces y baterías. En paralelo suena brutal también.

Sorprendido

Llevo unos años en Universal Audio y no hacía mucho caso a estos compresores y me ha encantado el tono que proporciona, ya sea a voces o guitarras. Espero probarlo en breve en bajo y seguro que será excepcional.
