Nothing could be easier.
It has XLR in and out.
AND the lights do the rest.
Tower arch is simple and easy to understand at a glance.
Excellent machine, used on battery bus, mix globlal, keyboards ..., recording as mix.
I use it for 2 years.
I have other compressors but this one is always available, ready to serve.
What I like most: ease of use and sound.
If one offers me another not too expensive, I'm doing.
I add here that my rating reflects the taste I have for this machine that I have chosen for its sound and its specificities. It is therefore perfectly suited to my use and my ear.
I note that the choice of such a machine must not only be done based on what everyone wants to do.
