Rackable? probably ... I do not know
It is simple (no effects ... but frankly I do not see the point where the price pierces them now).
There are about all the connections you want.
A strength: reliability: no spitting ... the knobs. It slides perfectly despite the age and dust ...

UTILIZATION

A machine of great simplicity. The instructions can be read just for fun (the guys at Mackie of humor!). It is very simple and very clear ... There is an overall pattern that allows totu understanding of the beast.

SOUNDS

So there: hat! I am working stream for a fairly old machine, the sound quality is perfect. Using the XLR inputs, good cables ... no breath. The equalizer is good.

OVERALL OPINION

I have over 10 years: no fault and always the same ease of use (they must be bored to customer service ... because my Mackie Onyx seems to be of the same quality).
I had several other consoles including a Berhingher was a priori more attractive (more channels, effects ...) except that the headphone jack I remained between the fingers (the quality is frankly to be desired).
So the VLZ was a little more expensive but it was justified!
