Input Selection
Many monitor controllers feature additional inputs. These are typically used to monitor something other than your DAW through your studio monitors.

Output – Speaker Selection
Many engineers choose to include multiple sets of monitors in their studio. It’s not uncommon to see professional recording studios feature a pair of near-field monitors, a pair of far-field monitors, and one or two small cube-style monitors.

Switch between different sets of monitors each have their own quirks, and allow you to hear how a track translates to different types of speakers. By multiple outputs you can toggle between monitors with ease. Without a monitor controller, you’d have to crawl behind your desk and reconfigure your output connections manually.

Customer reviews

It is just fantastic – does not affect the stereo image at all. Stepped and very precise. I feed it from my Mytek DA and ESI. Switcher function is also great. No clicks/pops. Build is sturdy. Since it is passive no need for a power cord. 7blanche / gearspace

I purchased a LittleKnob, been using it for 3 days and can say i am very pleased with it. Its the stepped version and is very smooth and well built all round. Its smaller than i imagined from pictures but i like it! I have an active pair of Focal CMS 65 on 1 out put and a pair of pssive celestion and Marantz amplifier on the other output. Noise/pop free when switching and can honestly hear no difference in sound/image compared to when my monitors were direct from my Apogee. 

Great price and shipped in less than a week to UK . Very pleased Ricky3278/ gearspace

Mine is still working perfectly, after nearly a year, being used every day.
It is very handy having 2 ins and outs. I can easily switch between my active kh120‘s, and also my power amp/ATC’s. TheBrightSide / gearspace

Studio monitor controller volume knob switcher

LittleKnob passive studio monitor controller, designed for DAW signal routing volume control of monitors or speakers without compromises – due to dual stereo solid state network. Both (L/R) sides are separated, without any electrical relation (connection) between them.

Select A or B Input Source

Allow you to select between multiple inputs and outputs, making it easy to compare your DAW mix to a reference mix from your CD player, or to audition your mix on your studio reference monitors or your hi-fi speakers with a switch changeover.

Phase Invert R side of stereo signal

Phase inversion is a subtle, yet versatile music production tool capable of many distinguished feats. First, what is phase inversion? Inverting a wave’s phase means swapping the location of its peaks and troughs. This creates cancellation when peaks of one wave coincide with the troughs of the other wave.

Stereo to mono- Mono Compatibility test

The word ‘Mono’ is panned absolutely center. This means both Left and Right speakers reproduce the same word ‘Mono’ at the same volume. This also sounds ‘mono’ and so panned to the middle.

Checking your mix for Mono compatibility as you go is a good preventative measure. Sometimes just because a mix sounds good in stereo doesn’t mean it will sound good when the left and right channels are combined into a mono signal. In some cases, you may hear what is known as comb-filtering, which will color the sound of your mix and cause peaks and dips in its frequency response. In some cases, instruments may lose their integrity or even seem to completely disappear from the mix!

Phase Invert R + Mono mode

Reversing the phase of the right channel and mono-ing it with the left and sending the result to both speakers is particularly useful for assessing the width content of your mix and distortion characteristic by effectively replacing the ‘centre image’ with the out-of-phase information.

This provides an excellent way to check mono compatibility and to also learn spatial tricks from your favourite reference material.
