Impression:
First, it is a visual indication of musical spectrum, and there are several modes of operation, such as normal, inverted, full or part of the spectrum and off.
Second, it is an active parametric equalizer, though it is not as complex as professional units (which do cost anything from 5 to 30 times its price).
Third, it can be used as a karaoke unit
Fourth, it can be used as a spatializer, or simply put, it can simulate various listening environments, such as cinema, church, hall, rock concert, etc.
On top of it all, it’s completely digitally controlled, which means great precision, easy repeatability, excellent longevity through a complete lack of mechanics, and above all, memory.
