. RMS STABLE     . COHESION     . TRANSPARENCY

TubeMU, It is a vintage compressor that emulates the density and the RMS generated in this type of device equipped with valves with a variable «MU» factor, initially designed for radio frequency. This one in particular is called “Variable - Mu” and it means that the amplification gain is variable by polarizing the “grids of the first two triode valves” with negative voltage. The higher the amplified signal, by the internal side chain circuit, the higher the control voltage and therefore the greater the gain reduction. The uniformity of the signal is given because its control circuit is of the “Feedback Compressor” type and for that reason this type of machine has the distinctive musicality.

These compressors behave in a totally different way from the others, such as Optics, VCA, FET, and Diode Bridge, the latter also very similar to the "Variable - Mu" but with greater distortion.

With TubeMU, we can obtain large and uniform reverbs, as in many productions of a few years ago and of the style “Trance” current. A smooth way to embellish all kinds of instruments, complete mixes, and grouping buses for linking instruments and vocals.

 

TubeMUIt's surely the sweetest compressor in your tool drawer, but don't worry if you don't know if it will be optimal for this style or that. TubeMU it is an all-rounder.

INTRODUCTION VIDEO

INPUT AT CONTROL


INPUT: It works by amplifying the signal like any other input control, but also increasing the signal in the side chain, and therefore generating compression. Many of them, lacked "Threshold" running compression as is the case with TubeMU.

For this reason, any increase or attenuation of "INPUT" will affect the results. We can also appreciate an increase in gain before exceeding the signal threshold, where the compression process will begin.

 

DRY / WET SHARING


DRY / WET: We can get a mix of the two, or just “Wet” as the compressor output level. 

Both Dry and Wet are protected by "LIMIT". In this way we can mix the two channels without worrying about the small peaks that appear due to the sum.

FREQUENCY AND RATIO GIVING SHAPE

SIDE FREQ: adjusts the working frequency of the side chain, adding more body and nuance in compression. The setting is intuitive, sticking to nothing in particular, except that the higher the frequency, the less possibility of pumping. Just adjust until we get the sound that we like the most.

VUMETER  /  GR-LEVEL: with “LEVEL” output signal measurement options and “GR” gain reduction. The “green” mark is the most stable and intense point. Variable Mu, when it exceeds a certain control voltage, it remains out of range, and this is due to saturation of "Mu" when the "Grids" of the first two compression valves can no longer tolerate any more negative stress. It is as if they reached the maximum of producing profit variation.
