VMU – is a traditional all-tube device with soft compression, commonly used on the mastering stage. It can be used in double single or linked mode.

Slight soft compression with settable attack and release time lets you reach the desired results in the mastering process. The device has traditional architecture, but a unique schematic, so its sound is individual. High-quality stepped potentiometers and attack/release times rotary switchers complement the fully balanced schematic in aspiration to build the precision instrument with linear frequency response and minimal distortions. The device includes 6 transformers and 6 double triode tubes, which fill the sound with harmonics and make the sound rich and soft.
