What does it do?
Nero perfectly matches the volume of the left and right channels of your stereo signal using Audient’s custom Precision Matched Attenuation Technology.
How does it help?
Unlike other monitor controllers, this prevents any deviation in volume between your left and right monitors or unbalancing of your stereo image, enabling you to monitor accurately and mix with confidence.
Reference your mixes on up to three sets of speakers, independently set and match volume for all speakers and audition and assign your sub to any monitor path. Nero also provides one dedicated monitor grade headphone amp and three foldback grade headphone amps, making sure you’re ready to take on the loudest of sessions with crystal clear headphone mixes.
Easily assign a sub to activate when switching to a monitor path of choice but maintain the ability to switch it on and off without losing your saved preset. Nero also lets you audition the sub on any alternative set of speakers without forcing you to assign it permanently.
