So I've tried to research the simple subject of the Master Cue being "post master fader" on the DJM series of mixers, and why it's setup like this.
I have read the explanation that if you set you channel gains to peak the channel at around 0Db, and then set your master level to 0Db, then when you cue the master using your headphones, you should hear the master nice and loud like any other channel.
You can then use the cue/master blend knob to listen to your mix.
The problem, is that on every single system I've ever played on, the master level out on the mixer is always WAY WAY WAY lower than 0Db. If you turned the mixer up to 0dB, you'd go deaf instantly.
In club situations, you cannot touch the system rack. Does anyone really run their mixers this hot in a real club situation? I mean on the same system (without touching the outboard levels), if I hookup a Rane or something, it's not really more or less "hot" than the Pioneer, except of course, if I ran the Pioneer at 0Db, which would be insane.
Now, on equivalent mixers like the A&H Xone's, Rane's, etc., the master out cues are all pre-master fader. Regardless of the setting of that master level knob, I can cue the master and it's at a perfectly lovely level. On the Pioneer, I can't use the cue/master knob at all, because the master is barely audible in the phones. I get around this by just using multiple cue'd channels at once, but it's not as nice.
Is this something that could be a firmware option in the DJM-900/2000?
Unless the places I play are hooked up really oddly... but even using my Mackie's at home, if I crank up the master out to 0dB, it's SUPER HOT.
