Mackie BIG KNOB PASSIVE Monitor Controller

Budget friendly and awesome controls . Performance and Design superb 👌

This is built like a tank, just like all the reviews say. I use it to switch io b/w 2 sources and my monitors/headphone amp setup. This equipment works beautifully without any signal coloring to my ear. I didn't realize how convenient handling four different volume knobs with just one big knob would be. The mute and dim features makes it even more handy. An absolute recommend and thumbs up from me for anyone who work multiple inputs and outputs. Cheers.

Good working, easy , smooth and gentle knobs, and can connect to stereo inputs to go to two different stereo outputs. Very handy.

First i was afraid after seeing a couple of negetive review about hiss or buzzing on full volume, but there is nothing like this even this eliminates all ground loop issues. Simply I loved it. But if there was a headphone out then it would be pure gold

Excellent tool for a/b listening as well as listening to external sources via aux input without altering your DAW or hardware signal chain as it sits right at the end of the output chain. It is completely passive and has dedicated dim and mute buttons to protect your speakers from excess amplifications and blow outs. An indispensable tool when working with different sets of speakers.

Great product, a must have piece of gear in your studios...

Excelente material mejora mucho mi flujo de trabajo

I really like the design of this, but found without the proper grounding of a power supply you can introduce noise into the signal. I also noticed as you bring the attenuator knob down to the lower quarter, the left/right speaker channels become unbalanced. So if you are monitoring in this range and mixing your song, you may get a rude shock when it comes to listening on another stereo device.

Fine, but the buttons get loose by the time. You need press it many times to work properly. Good just for sometime and then you need to upgrade for something better

プッシュプルの真空管アンプを導入したところ、ボリューム最小でも出力が大き過ぎたので、ボリュームコントローラーを探してたどり着きました。 機能的には申し分ないし、コンソールに配置されたボタン、ボリュームノブの質感も値段を感じさせない高級感があります。 急いで購入したので、Mono、Mute、Dimスイッチがあることに驚きました。 あと、サイズが意外と大きいです。 多分、これくらいだろうと勝手な想像をしていたのですが、ふた周りくらい大きかったです（笑） 商品説明に掲載されていないので、盲点でした。 で、肝心のサイズは高さ79×横幅137×奥行き142mm、重量1kgです。 これから購入する方は予めチェックしておきましょうね。

I was looking for a high quality passive volume control to a pair of powered speakers with 2 input sources. The unit appears very well made, the volume control works flawlessly and feels positive to use, and I don’t suffer from any extraneous noise or interference. It wasn’t the cheapest option, but my initial impressions are that it is well worth the higher price.
