Phase Invert R + Master Mono Switch: https://vintagemaker.net/documentation/#phase-invert-r-master-mono-mode
Rack Monitor Controller – 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. *they perform a test-type function (since you only use this function periodically) and because of the passive attenuator nature recommended to use at 75 -100% attenuator volume (or max the volume) *the efficiency of the phase decreases proportionally as the volume decreases.

Joseph Webster –
Exactly what I needed
Thrilled with the result here. I needed to make some changes to my setup and decided to go with this unit for monitor control. Paul went back and forth with me to make sure I had what I needed and sent me proof of concept the same day I put in the request. Unit came in perfect condition, ahead of time, with extremely fast shipping. Paul's communication was top notch, and I now have a great new piece of custom gear that works great with my setup. Thanks again!
