    Customers are mixed about the sound quality of the audio midi interface. Some mention that the sound was good, does not alter the sound at all, and the few functions are useful and work well.

    "This is a steal for the price. I can easily switch between two sets of monitors in an instant. Having an alternate input has proven useful too." Read more

    "...That's not good for production... as it can cause static, or actually not function at the proper gain or volume...." Read more

    31 customers mention11 positive20 negative

    Customers are mixed about the volume of the audio midi interface. Some mention that the mute button comes in handy for silencing those pop up video ads when they're on the phone. They also say that the control, easy access dim, mono, and muting buttons are really handy. However, others say that when they’re on input B, the volume drops like 20db, one of the channels is a little louder than the other, and that it reduces their system volume by more than half.

    "One of the channels is a little louder than the other...." Read more

    "...to "Mono" out my mixes via the BK's controls, the Dim and Mute buttons are really handy when taking phone calls or attending to the cross office..." Read more

    "...’s a noticeable attenuation of the high end, but also a major downgrade in overall volume, even when maxed...." Read more

    "...use but it degraded the mids / high end response, not to mention a loss of volume." Read more

    Beautifully simple and effective.
    5 Stars
    Beautifully simple and effective.
    I bought this to be able to control the volume of my PA system independently of my studio monitors. When I first got it I thought something had gotten on it, but it's just the paint lol. It works great, feels like it's a rugged build, and adds a layer against accidentally damaging your speakers. The dim button is my favorite part of the unit. It dims enough to go from jamming with a drummer to hearing if someone's at the door with no clicks or pops in the process.

    5.0 out of 5 stars Perfect Signal Switcher for my needs
    Reviewed in the United States on April 22, 2023
    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!

    5.0 out of 5 stars Modifiable to use common subwoofer
    Reviewed in the United States on February 1, 2023
    What I wanted was a fully passive monitor control that switched two stereo inputs into two stereo outputs, AND offers a common subwoofer output regardless of the monitors chosen. I noticed this had some space in the rear panel once the 1/8” jack would be removed, so I got a slightly used one from Amazon warehouse and drilled and soldered. Pic attached. Works fine, although this is a bit of an advanced mod. I used the same 150ohm resistors on the sub outs used on the monitor outs, on both pins 2 and 3.

    Speaking of which, this unit runs only impedance balanced (it's passive, just using resistors, rather than active balancing or transformer balancing). Sure it accepts balanced connections, but pin 3 just runs 150ohms to ground both in and out, which will net fairly modest noise removal from the cable run. Otherwise they’d need a very fancy potentiometer double dual gang with very strict tolerances. Unbal to monitors with short cable runs not such a problem, but it is somewhat of a volume loss, beyond the loss this unit already has by design. Monitors are typically too loud anyway when driven at line level.

    There are also a pair of 10uF electrolytics…polarized commodity ones…between input and output. I shunted those off but most people should probably leave them, they don’t hurt the sound much. And 100pf ceramic caps avoiding RF interference coming down the line, perhaps bleeding off a touch of high end in the process. I left those.

    The next day (not shown in the photo) I also added an On-Off-On toggle under the logo on the back, that offers follow, mute, and solo for the subwoofer, handy for Room EQ Wizard or just hearing what your subs vs monitors are doing. The solo works in conjunction with the main mute button as a fast A/B.

    Anyway this did solve my problem after modding and the unit is heavy and the knob feels smooth and heavy like a hifi receiver. I improved the signal path a touch and the functionality a ton. I just wanted to show this mod is possible and is good enough to avoid spending more if you can hack it and that’s all you need.
