Universal Audio 6176 Reviews

Should probably not be your first channel strip, but a classic.

By Johannes

A very specific "character" channel strip, and if you're after THAT sound, certainly the classiest way to achieve it. "That" sound: rich, warm, nuanced, but somewhat limited. One reason I wouldn't recommend this as someone's first piece of outboard gear (it was mine ...), is that the controls are very unique and not always intuitive. Especially the EQ settings on the preamp side are a little clunky and don't always seem to do all that much. If you're searching for silky shimmering highs, a Neve type preamp/EQ would get you there more reliably. If you want to go straight into your audio interface, bypassing its built in preamp, you might also be underwhelmed by its power, and end up pushing the compressor output control for more oomph, which obviously has its downsides. As for that compressor: It's an 1176, so clearly one of the most legendary units, but again, the controls in this layout are a little weird. The 1676 is probably the coolest looking preamp/compressor out there, with its enormous old-timey black knobs and its whole vibe. I don't regret getting it, but it had a bit of a steep learning curve and delivered fewer "wow" moments than I had hoped for. My advice would be to make sure this is exactly the sound you're looking for. It totally shines as a bass DI. For vocals, it's an acquired taste, and not the best choice for darker mics, such as 47 types, at least not if you want that modern sheen and sparkle.

Vocals are tailored easily. Acoustic guitars are rich and full. Compression unit can be subtle. Easy to use with a very classic sound for your recordings.
