Apogee pre-amps

Hello !
(i did a search about this and couldnt find an answer).

I have an Apogee Duet, and just brought an Ensemble.

I was told that they were DIGITAL PREAMPs, that A/D conversion happened before the Pre Amps stage. This doesn't make too much sens to me, is it right?

Also, when I select in Maestro " XLR Line " for my input 1, is it still going through the pre amp? or is it bypassing the Pre Amp ? (What if I want to bypass pre amps frm inputs 3 and 4 ? )


Thanks guys !

Im not even sure how that would even be possible(the whole conversion then amplification thing). We just got an ensemble after alot of research and from what I gather, apogee set out to make the most transparent pre's they could for the ensemble. Now, almost all of the controls are in the apogee's Maestro software control, but I'm pretty sure they are actual preamps. Pretty good ones too, at least compared to onyx, FMR, and a BLUE Robbie pre.
As far as bypassing the preamp, I believe its like any other unit like this (all in 1 types), you are gonna be running through the preamp, but if you use the gain on you ext. pre, you might not have to gain up the ensemble enough for its pre's to color the signal that much

Thats the thing, they are REALLY transparent and they are controlled digitally, those are the reasons I have to actually belive about this being true.....

I actually don't care as long as they sound good, which they do, but I just want to be informed and want to know what im dealling with.

So the other question still is:

when choosing "XLR Line" in input 1 is it still going through the Pre - Amp ?
What would be the way of bypassing the pre amps ?

THANKS !!

Yes, you can completely bypass the preamps by setting the inputs to XLR line in Maestro.
The preamps are the TI PGA2500 chips with +10dB pad, the RME Fireface 400 and the MOTU 828mk3 also use the same chips.
I personally think they are OK but nothing special compared to other IC pres.

yea, the reason he probably called it digital because the gain is controlled digitally, so it's not all discrete.
