I use this unit in my mostly DAW-less mini home studio. The in total three masters come in very handy and are worth the slight price lift from the IMIX 7.1. No hum or noise, even with multiple masters/ins activated at the same time. The sliders could been a bit stiffer, they move with the slightest touch, I have no complaints regarding the buttons or knobs.
The flexibility this product offers me is great, I use one IMIX master channels with a mixer recorder, to expand and make routing easier (e.g. effects processing). One master is used for my sampler, which can now also be easily be used as an effects unit for all the line ins. The other Master is used for my hifi system.
The panel is easy to use, routing is very intuitive and flexible, with gain and volume on line ins and master channels with additional tone adjustments and vu-leds are usefull. I've yet to test the Mic ports, but I have other pre-amp options for those. One gripe could be that there are mostly phono line inserts, I don't care about this, most of my connected synths only have line-outs. I also did not use the multiple line selector button for switching to another connected device on the same channel, but cloud see the advantage not having to plug/un-plug, they are exclusive to each other so only one can be used at a time.
Of course I could have bought a bigger mixer/MTR with a ton of routing options, but that would have been too intimidating for me to start my step-by-step journey and learning process.
