Hi all, I’m a long time Denon, Engine DJ and other DJ mixer / PA / Speakers / Equipment of various sizes, so do have a fairly good grasp on audio and other things related to this type of equipment in general.
However…having had in the past or still owning SC6000s, a Prime2, Prime4, for my standalone backup I have now “downgraded” to a Mixstream Pro Go, and there are a couple of things that are puzzling me…
I’m wondering if anyone has any useful info regarding the master output on the Mixtream Pro Go - I’ve had a dig around the user manual, online (in general about the unit, videos etc) and also on this forum, but I can’t see any specifics on the following questions;
- There seems to be no adjustment internally (or via a physical switch on the back etc) in the menus for the Master Output level, aside from the main output volume pot and the menu based toggle option for summing to Mono. The Master output on my unit seems to be incredibly loud with no good explanation…so wondering if anyone has the same “issue”. While you might think this is not an issue and it’s a good thing to have a load of headroom on the master output - I literally swapped this unit straight out of the same setup where my Prime 4 was being used, same cables, amps, speakers, even same hard drive of source material files, everything - I just dropped it in place of the 4, and the output is totally different. The Master volume pot is only at the 9 or 10 o’clock position and it’s too much…any ideas!?
- The Master VU Level Indicator also has no numbered db markings/rating, just 4 blue LEDs with one White LED at the top. Wondering if anybody knows if the White LED is definitely supposed to represent “0db” as common sense might suggest, or whether these LEDs and their levels are set by default to something else?
Many thanks - hopefully some good answers by reply!
Funny how diff minds work differently - my first thought would be that my Prime 4 is actually not loud enough for some reason (hitting the limiter etc)
Anyway, it’s difficult to say what is the problem this way - better would be to show us with 2 videos how you have gain staging set up using the Prime 4 vs the same song playing with Mixstream.
I’ve seen plenty of WEIRD gain staging, esp coming from old cats that use digital setups like they still have that old analog Citronic without gain pots 
Most of the time it doesn’t matter much but when you have build in limiters and VU meters that don’t actually represent master signal strenght in analog terms then you might be messing up the sound.
I sold the Prime4 and replaced with the Mixtream Pro Go as my only all-in-one controller, so I can’t do any kind of comparison video. But as mentioned - I’m playing the same files, through the same, cables (balanced XLR out), amps & speakers, and at 9 or 10 o’clock on the master output volume pot on the MSPG, the sound is very loud compared to the Prime4. Gain staging etc as you describe doesn’t really come into this question. The channel volume fader is all the way up, the crossfader is all the way over (and I tried both left and right and combinations of fader curve etc), and the input gain/trim knob is where I would expect it for most of my digital files - around 11 o’clock…and still the same - the master output seems waaaay too loud. Not distorted, just very loud. And compared to the Prime4 (I’m not sure if they share exactly the same sound card or not), I would expect it to be the same, or if any difference - that the Prime4 might have had more headroom and a larger output capability given that it’s supposed to be a more capable or more professional piece of equipment…

Since you cannot compare I guess this is more of a request if someone else that has both can cofirm your opservation - there should be, seen plenty of people here with multiple Engine OS products 
(posting just to keep the thread visibility)
Oh and I belive I gave you the answer to question 2.: they are not calibrated and can be used only to gauge if your output stays relatively consistent during your set.
