specifications required.

- 6 channel input (4 mic , 2 auxillary)
- stereo output
- tone, bass , and treble control for each input...

You might bear in mind how cheap good quality commercial mixers are, you can probably buy one for less than the cost of the knobs for building your own.
 
i know that.. but i have to make it myself.. have my step by step evaluation done on regular basis..


ill be glad if u can give me some circuits for makin a mixer.. not 1 .. but a few.. and also theory related to it..
 
Google finds a few.

i have checked some of them and even tried makin a few..
those circuits dont seem to work.. and at times do not give desired outputs..
i m lookin for something that has been tried.... preferably using ICs that are easily available ....
 
here are some simple circuits

pretty basic circuits
 

I would say that circuit is exactly what you are looking for, and it looks excellent - I've had it bookmarked for years.

If it doesn't work, or gives unexpected results, I would suggest you're probably not building it correctly?.

A mixer is a pretty simple device, and lends itself well to modular construction, and the example mentioned (as with pretty well all others) doesn't require any hard to find devices.
