Mackie Passive 2X2 Studio Monitor Controller, USB, Black

This product m has a grounding issue and there is an awful buzz once plugged in. I had a look online on forums and many others have had this problem with no solution found ... don't buy this faulty product.

less than a year volume control became erratic

Ótimo controller. Custo benefício é praticidade.Fácil de montar e resultado sonoro muito bom

I am using this MACKIE Big Knob for a slightly different purpose. When I first set up my Tascam Model 12 Mixer/Recorder over a year ago I dedicated Channels 9&10 to the Pre-Amp Out of my uTurn Turntable. As much as the Tascam Model 12 is the Hub to my Music Production it is also a part of our Music Rooms listening experience.Now that my set up has grown (with seemingly no end in sight) I wanted to free up those 2 Channels, as the Turntable is not used as frequently (we have a +Audio System in our living room for most of our Vinyl listening).I decided to get a Passive Switcher. In the old days I would have just gone down to my local electronics shop and bought the components and built one but those days of those kind of shops are long gone.I wanted something small. In my research I found a Mackie "Big Knob" Passive Monitor Controller. It is typically used to switch between 2 set of Monitors, like a main and reference pair. But you can also connect two sets of inputs and easily switch between them, which is what I needed.So I just bought one. The build quality is excellent, it is small enough that it fits nicely to the right/rear of my Tascam Model 12. It's out of the way but with easy access.Being passive, the minimal amount of electronics used makes it ultra-low noise and maximum signal integrity. In fact comparing it to the direct signals into the Tascam Model 10 and coming out of the Big Knob there is zero difference, no noise, coloration or volume loss. I don't understand some of the reviews that claim it was either Noisy or The Volume was low. Non of that was the case with mine. I can only suspect "USER Error" or connecting it improperly from those reviewers.It also has some buttons for Mono, Mute, and Dim which might come in handy.Simple, Low cost Solution and based upon my using it I am sure it also makes for a perfect Monitor Controller if that is what you need!

Hace su función perfectamente, no mete ruido. La perilla de volumen se siente firme. Su construcción es muy buena ya q su carcaza es de metal. Me gustó mucho y por tanto lo recomiendo.

Tout est dans le titre ….

This One knob is a brilliant piece of kit for a home studio if you have two sets of monitors. I use this in conjunction with a small(ish) behringer mixer to give me more headphone control etc. The mono function is very handy for checking phase issues!Nb.I have no noise problems at my end.Get one!!
