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..

.........................................
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

6 Input Mixer

Parametric and Sub-Woofer Equaliser

3 Band Graphic Equalizer

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.

M sorry Goodwin but in ur previous post u did not give me any circuit.. so which circuit are u reffering to here??..


r u talkin abt the circuit on MIXER 6+ channel in English
