Mixer mod Question

[FZfile]

I have no idea if this is the best place to post this so I am cross posting.

I bought the Beringer 802 mixer (please dont hate me) and I definitely want to do the pre/post mod.

....which is that each of the 4 mono chans are set up as AUX1 > Pre fader send and AUX2 > Post fader send.
However you can switch the AUX2 to Pre fader by cutting the POST jumper and adding a PRE jumper (this is clearly labled on the board)

I figure since there are only two AUX sends on this humble board (please dont hurt me) I only need to convert 1 channel.

So............my question is this:

Can I cheat and do this from the underside of the board?????
(i.e. without having to dis-assemble all of the knobs and jack-nuts etc.)

I think I probably know the answer already.

I know some will say that if I have to ask then I should have someone more qualified do it but I have confidence in my soldering skills just not so much in dis-assembling the whole mixer.

Besides, how else am i gonna learn these basic survival skills.

Any help will help.
Thanks

I haven't looked at the mixer you speak of, but if it's anything like a Mackie (or even suspiciously similar) you'll have to take the whole thing apart. Perhaps Behringer improved upon them by adding a removable bottom cover, but I imagine you would've noticed it. I use a half dozen empty CD-R spindle covers to hold the different colored knobs and fader caps, then put their bases back on to prevent spillage. Then I pull the screws, and finally the allen bolts spread across the face of the mixer. These get locked in spindles as well. As the bolts on the face of the mixer come out, the knobs and buttons will drop through their cut-outs until the circuit board is resting on the bottom. Here I'll usually flip the board over, rest the edges of the face plate on some stand-offs (2x4 scraps in my case) so it's not laying on it's unsecured knobs, and lift the bottom of the console off. You should now be able to lift the circuit board out to work on either side easily. Maybe they designed it so you can get to the bottom traces without removing the PCB from the face plate, I really don't know. By the way, most techs will do the circuit board work for a few bucks if you take the thing apart and put it back together again yourself. I'd probably throw some mini toggles in there to make both sends switchable, I'd hate to change my mind later and have to take it apart again. HTH

You read my mind about the switch but I'll do that later cause I have to get parts and want to use this thing this weekend.

I was thinking that I could put the switch(es) in one of the EQ holes because the EQ on this mixer is ALMOST unusable.

I miss the EQ on my Portastudio.....but I got this mixer to have 4 cheap preamps and a little routing options. I've got plenty of EQ choices on my 880.

I'll let you know how it worked out.

Thanks again,
