From Modular "BIG POT" Active Monitor Controller New
« on: February 28, 2020, 07:56:44 AM »
Since the original link is dead, I repost
In order to meet my needs, I made some simple modifications. The diagram is in the attachment. Forgive me for being a novice. Please help me to see if there are any errors. Thank you for your help. I know I used a clumsy way to do balanced output, which is very troublesome to build. I want to choose drivers such as DRV134, but they are very expensive. I want to know if there is any way to simplify my schematic. Regarding mono switches, I know they add extra volume, but I don't think they are used often, so it doesn't matter.Regarding the "input" buffer part, I'm not sure if the impedance is enough, I always feel that I have set a lot of extra parts, but I'm not sure.

Because it was too messy, I re-drawn the wiring diagrams (they represent only one module, please ignore the pins that are not drawn)

I want to be able to adjust the ratio of the two channels like the "MTC monitor controller", but it seems that the potentiometer will attenuate the signal when it is in the middle. I haven't thought of a solution yet :'(
