Audient Nero

Rugged, reliable, and transparent; the Audient Nero offers seamless switching between systems with no audible coloration. I initially purchased the Nero as a means to quickly switch between nearfield and midfield monitors. Being able to instantly switch in/out a sub on either monitoring set up has proved very useful. The four independent headphone sends are a godsend when recording an ensemble.
I initially thought the built-in talkback was a bonus feature but I now rely on it during every live session to communicate with musicians/singers tracking in the next room.
Every studio tool needs to prove its worthiness. The Audient Nero has helped both my productivity (no more switching speaker leads) and my ability to communicate (no more shouting through the wall).

Very pleased with this product. Looks good, is versatile, and as the various reviews have stated, I also could not detect any colouration to the sound.
This unit was reviewed in Sound On Sound, so worth a read. What that review omitted to mention, which is why I only gave 4 stars for features, is that the mono SUB output can only be active when added to one of the other 3 outputs. So if you have a full-range 'grot-box' mono speaker, you can't solo it from that SUB output. That fact reduces the available outputs from 4 to 3 (under some scenarios). Missed opportunity I think. What you need to do is use one of the stereo outputs, configure it as mono, and connect your mono grot-box to the L output of that stereo output pair. A perfectly valid workaround but not what I was expecting!
5-stars is deserved really, as it does include Polarity and Cut combination so you can listen to the difference signal. Hugh Robjohns loves that, maybe I will too!
Great piece of gear from a fab manufacturer at an amazing price.
