My passive mixer!

[Diederikds]

Hi guys,

I wanted to share my passive mixer I finished last night. It is balanced 16 in/ 2 out.
I didn't incorporate switches to short unused inputs, I will be using dummy plugs when needed.

I used RC55 0,1% precision resistors by Welwyn. 

I still have to test for noise and LR balance.

BTW: It is my first DIY project!

Another picture!

Very cool! What are you using for makeup-gain?

I will be testing with Universal Audio 710 (twin-finity) pre amps. They are switchable from transistor to tube circuit.
Low noise from the trans circuit is interesting. Blending with the tube circuit might make things even more interesting.

Right! Altough I just briefly tested the 710, I must say I wasn`t that impressed with it`s tone(s). But if you have two of them I presume you must like them alot!  8)
