These monitor selectors are getting harder and harder to find at a reasonable price. So far, this has worked amazingly well to switch between my Genelec & KRK's. No popping at all. Easy to setup in seconds, and plenty of on the fly options.

I love the Mackie Big Knob. Also I couldn't find anything else on the market that does it's job, except for possibly something all the way in China. I have my studio laptop going to input A, and my tv going to input B so it doubles as a home theatre speaker controller. I bought Mackie Cr5x monitors and have another set of Bose desktop speakers to switch between. This is so great to do A / B speaker references. You can only listen to either speaker set A or B at a time, that's for better referencing. For home theatre I had to run an additional output direct from the tv to speaker set A so I can hear both speaker sets together. Still not bad because this isn't even designed for home theatre. I don't know what I would do without this, and the knob feels smooth as melted butter. Now if I can only get up from watching tv to produce a track!

Bothers products to help me switch between multiple monitoring functions and speakers to be able to switch back-and-forth from Yamaha studio monitors as a second reference and main Adam audio three-way speakers as soon as I plug this product in The sound quality went down more than 75% as supposed to just using audio interface only good thing about this product is the knob size other than that not worth it

Overall this product is a nice quality for the price and exactly what I needed for my setup to A/ B between my two monitor sets. However the loss of volume is far too much to where in order for me to have it where I need it I need to crank my Adam studio monitor volume knobs and that causes the tweeters to hiss louder. Returned and I'll be upgrading to a powered monitor controller.

This is a perfect addition to my home studio. I wanted a switch that would let me sample 2 different sets of studio monitors. I am using a Clarett 4 PRE going into an iMac with Bose S-1's and Kali LP6 monitors. I wanted the ability to switch back and forth. The Big Knob has 1 large knob for volume control. Then switching for: A/B monitor source, mono, must, and a dim switch to instantly reduce the volume. Exactly what I wanted. Heavy and built extremely well. Also....no noise introduction from adding it to the chain between the Clarett and the computer. Happy with this purchase.

I did an initial review that I was taking it back to GC because it "colored" my sound and dampened it... after reading other comments out there in the web and watching YouTube I found that I needed to make changes to my equipment settings... which is odd because this thing is"passive".. but suddenly it started sounding as clear as if it wasn't there at all... I ultimately love this piece of gear and I wil be keeping it... I give it "4" stars because it should have sounded just like my original mix without doing anything else, because it is "passive"... I do recommend the Mackie BigKnob passive because it does not color sound (once you make seeing changes, mostly volume adjustments in your interface), it has the primary functions that you need like volume control within reach, speaker comparison, and mute... and it doesn't take up alot of real estate on your desk top... lastly the price for what you get is unbelievable... Hopefully it will last longer than my Mackie MCU Pro mixer did 🤣😂🤣😂
