I got a behringer djx700 as my first mixer 2nd hand from a m8 4 years or longer ago, it's still running today and I mix at least 1or2 hrs EVERYDAY.
I am looking to upgrade tho as it's begginning to die...
Damage:
Phono / line switches somehow got broken on channels 1 and 4 so it's now a 2 channel mixer really. (These switches do seem fragile ish)
Channel 3 mid eq adjuster just the other day became stiff i've no idea why.
Crossfader as of recent occasionally bleeds (almost unnoticably) i've only noticed on recordings when there's no drumbeat on the outloud tune. (To be fair the x-fader is F***king worn. never had a replacement) but ofc you can get around the bleed if you use channel volumes and leave x-fader in the middle!
The SUPRISING GOOD NEWS!:
After 4 years I can still play a real clean sounding set on it (with 2 channels).
This is not really a BAD mixer... you CAN get a very good sound out of it.
BAD TINGS:
Headphones plug-in is a BAD position but you get used to it.
Channel volume faders maybe aren't the smoothest / most accurate! But i get a good sound anyway cos i know my mixer...
Adjustable x-fader is reasonable / fine / decent but for instance they're much better on pioneers obviously. :X
A few things have broken over 4 years.
I DON'T CONSIDER THIS A BAD MIXER!
Maybe I've been lucky with it's long life, nice to have a contrasting story
