Customizing own portable mixer

[David Aliperti]

I OWN A ROLL 4 channel mixer, nothing fancy, bit noisy, dynamically not excellent, i used it for some low budget production, for audio guide track and few other things, with my fostex pd6 i am able to route my audio easely and have a better quality, now a need a good mixer, so i found a 442 used, in excellent condition, but was thinking another choice, a friend of mine , electronic engineer with a great expericne of hi end pre amp design, suggest me to replace 2 of 4 channels of my rolls with an top quality circuitry. so at least i could have 2 hi quality channels on my rolls, to be routed on main output clean with a good dinamic and great signal noice ratio, I hope make sense what i said.

any opinion ?

If you only need two good channels why don't you just go straight into your recorder via some decent mic amps and take the mixer out of the signal flow. It may not be worth modifying it and looking at other solutions to the noise problem. Also are you sure it is the mixer that is noisy and not the headphone amplifier in the mixer or recorder?

I use these Behringer mixers and they are low noise and fantastic value for money, OK not a trad ENG mixer but really useful on location, I normally feed mixed audio to tracks 1+2 and camera mic to 3+4 as my HPX371 camera has a very good audio matrix.
