Hey all. DIY audio/EE is all new to me, but I'm learning as I go and enjoying what I've done so far.
In an attempt to reduce stage volume for my church's praise team, I've been learning how to make my own simple passive devices. Last week, I made a headphone tap that took the speaker-level output of a power amp and made it happily work with a set of headphones.
Now, I was wondering if I can 'improve' upon this by combining the headphone tap circuit with a passive mixer circuit. I need to combine a monitor mix signal with a keyboard-out signal and allow the keyboardist to adjust the volumes of each channel herself.
So, here's my idea; please correct me where I'm wrong.
The mono headphone tap was a simple 1/4" jack to 150 ohm resistor to a 5k audio taper pot to the output 1/4" jack. If I try to combine that with the Rolls MX41b, I think I can simplify it to be:
For monitor channel: 1/4" jack to 5.1k ohm resistor to a 100k audio taper pot to a 10k resistor.
For keyboard channel: 1/4" jack to 100k audio taper pot to a 10k resistor.
Then, both of those channels to 1/8" output jack.
Thoughts?
