Hey there guys! I have an ambitious project that I might need some help with. I'd like to build myself a passive headphone mixer/control room matrix. Basically, it's just 4 stereo inputs and 4 stereo outputs that pretty much route straight through, but with the addition of certain things on each channel. Here's a mock up of the signal flow:
Sorry if that's a little confusing. Basically, there's 4 channels. A star denotes signals mixing together. The main inputs (Out 1-2 from my Saffire) are for the room monitors. There are two headphone monitoring channels (Out 3-4 and 5-6) that will go to their own sets of outputs, after being mixed in with a talkback mic (which needs a momentary switch on it) and mixed with the Aux in, which is the 4th channel. The aux in will also mix into the main inputs/outputs. After mixing with the aux, the mains will then go to a volume control with mute, dim, and mono buttons. After these controls, it will get split into highs and lows and go to two seperate Monitor and Sub outputs. This is more of a nice to have, so I might leave it out in my first design. I don't even have a sub at the moment anyways. Lastly there will be a second pathway from the main inputs before the controls that gets mixed in with the talkback mic and goes to a cue output, which will go into my headphone amp on my rack. It's essentially the main mix with talkback in it. I'm not even sure I would need the power, because ideally this whole thing is passive.
So here's the problem. I can solder till the cows come home, but I really don't know too much about electronics. I'm not sure how to wire things up, and most importantly, I don't know what components I need. I'm assuming it'd mostly be resistors, potentiometers, momentary switches, 1/4" jacks, and a cheap mic capsule but I'm really not sure what kind I need or how exactly to wire them up.
Would anyone be willing to help me out? Maybe draw up some schematics a noob could read with a parts list? I will love you forever!!
