Native / Apollo - Runs either natively on your macOS or Windows computer or on the DSP of your Apollo interface. Works with or without UA hardware.

Often cited as a crowning achievement of audio pioneer and UA founder Bill Putnam Sr., the 175B and 176 compressors are highly prized for their rich tube gain reduction character and immense sonic flexibility. Now, you can bring these legendary sounds into your studio with the only authentic plug-in emulation of the original UA 175B and 176 compressors.

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 groundbreaking. They were the first compressors purpose-built specifically for studio recording and mixing music, providing engineers with a revolutionary fast attack time and independently variable Attack and Release controls. This level of control was unprecedented at the time, making them indispensable tools.

Experience Deep Tube Sonics: Based on a pair of UA's meticulously maintained 1960s "golden units," the UA 175B and 176 Tube Compressor Collection delivers all the ultra-musical harmonics and colorful saturation of these original units. The emulation meticulously captures every nuance, down to their magical feedback compression circuit. This unique design provides softer compression at lower input levels, transitioning to a harder, nearly brickwall limiting at higher levels, giving you dynamic control that's both subtle and powerful.

Get the Rich Sound of an All-Around Champ: These plug-ins are perfect for virtually any source: vocals, drums, guitars, and more. The UA 175B and 176 plug-ins imbue your audio with all the character and "juice" of the originals—so accurate they're indistinguishable from the target hardware in blind listening tests. You can easily add depth to room mics or a drum bus, give your guitars unparalleled definition, perfectly seat a bass in a mix, and inject vocals with vibrant energy. For even more creative versatility, you can even turn off the compression entirely and use the 175B/176 plug-ins purely as a "tone box," lending rich tube textures galore to your tracks.
