Mackie Big Knob Studio

The main knob started crackling after few months of use, sometimes resulting in complete dropout of signal on one channel.
The headphones outs are useless because of 2dB difference between L and R channels ( no matter what input is used ).
Also the whole unit gets uncomfortably hot ( no nothing is shorted, it just runs hot and you cannot keep the hand on it for more that 10seconds ).
Would NOT buy again.

Solid packaging, all the cabling and accessories you might need to start off with. As an extra it included a key for Tracktion 4 but I'm not sure if that's still relevant.

The build quality is a bit inconsistent, some buttons are a bit clunky and not giving the same physical response as the rest -but the volume knob is super hifi-like though and it just feels satisfying to touch it. The frame is well designed and built, rubber feet is placed where it's needed. It's heating up quite much on the front side but unless you're putting something close up front to it it's barely noticeable. Just let it breathe.

I really like the overall look of the box, the LEDs are nice and we got good pack of features including built-in mic and push to talk button (which I've never seen before on interfaces in this price range). Can totally see myself using this in a small, half-professional recording setting. One thing I instantly wanted to try is how well it can drive my headphones on playback, but I was very soon surprised/disappointed that unless I'm wiring things up weird I am unable to do it. Oh well.

Sound-wise I have not gotten around to test the mic inputs yet, I'm struggling with driver problems for the time being (Win 10). The drivers are not automagically installed, despite what happens with most equipment these days. I downloaded the official driver and it still struggles to clear up the unknown hardware indicators in device manager. Despite this, in Windows with playback I have no issues, in DAWs however I am forced to use buffer sizes of 1024 samples or more or it starts to clip hard. I'm reading online that it's normal to use that setting for mixing but on my Focusrite I had none such limitation. I'll try to fix these regardless in the future, I am yet to go through the manuals as I'd rather experiment on my own (ease of use & setup and such nonsense).

Edit: Sorted out driver issues. Latency is fine now. However after much testing, I found the mic pre-s to be quite bad compared to my Focusrite Scarlett. Clipped the signal before the meter did and made my AT2020 sound like some cheap knockoff. Also there is some strange routing thing happening with direct monitoring - if the inputs are active it sends the signal out with no respect to where the knob is turned...

It's a nice looking monitor controller really.

So, i've had it for a few days, i use it everyday with my monitors, dont have much to say about them yet, the A channel which i use to my monitors works well... i havent used many of the other features yet, im gonna update it when i have tried with headphones and a microphone...
it does tend to get a bit warm with a long time usage, its still not hot enough for it to burn your fingers but it does get hotter than 40C, overall im quite satisfied with it, it works well for what i need it for as of right now.

Edit: so i've noticed a bit of a problem, at low volume as in turning to big knob down to low volume can cause an unbalance in the audio so the right becomes louder than the left, so i recommend just using the windows audio to turn up and down the volume and leave the big knob as it is.

another edit: this isn't a problem for some, but a feature i'd love to see on the product would be a way to disable the built in mic, as talking in a voice chat the other parties can hear themselves.
