Help with line mixer!!!

[Morning_Star]

I'm looking for a good DIY line level mixer. It needs to be very transparent class a circut. It also need to have TRS right and left ins on each channel. I would like it to have 6 channels, each with a mute button, thru outs, an output db meter, and a master fader. Maybe a small gain boost. All solid state. At the very least it should be 4 channels with volume control for each and a master TRS out. All in a rackmount 1U or 2U.

I will be using this for my studio monitor mixer. I would like it to have thru outs so that I can still have each piece connected to a seperate channel for recording but still have a master channel for auditioning. This will make everything much easier and my workflow much more convienent.

Your request sounds too general to garner much help. There are lots of summing plans on the board. Which one's do you like? How much do you want to spend? Why do you want a db meter on a monitor mix?

There are schematics for using TL074 to make a simple mixer. Just add your split trannies in front of each channel:

Hope that helps!

Accually that is great. This is just what I need. This is perfect.

Sorry if this is a common project but my search revealed nothing at the time.
I'm going to do some more searching for summing circut.

For the mute button can I just use a circut disrupting push on/off on the + lead? And how would I add it to a stereo signal without cross talk?

BTW. I'm willing to spend up to about $300 for everything. Otherwise I could probally find something that would work in the market. And I would like a db meter because I will be doing recording through this and I like to have a db meter on the stage before the interface.


Thanks for the help so far.
