Small mixer ideas!?

[3nity]

I need to build a small 2 stereos INputs to 1 stereo output.
I never looked into mixers before.. This are for my keyboards synths.
Thanks in advance.

Active/Passive?  Room to grow?  Pan? Aux inserts? Mute? Define your constraints/needs.

Hi boji.
Need a solution to mix 2 keyboards signals.
2 stereo line input.
Mute switch for now.
Passive better.
Thanks

Are the keyboard outputs balanced or unbalanced?

What will you feed the mixer output into?

Cheers

What’s the budget?  You can buy a small mixer for 50 to 100 dollars that can do this.  It’s doubtful you can build something cheaper.  It use to be a build in mix fuction on some Roland keyboards to handle this especial with their modules.

Hello 3nity, How are you?

You probably have your mixer sorted by this point, but just to let you know or someone else in the future that for Keyboards (unbalanced line level) this simple mixer circuit works great.
Having stereo is just a matter of having dual pots and double the schematic:
