Re: AAAAgghr only 16bit

I read this thread and thought: "Huh....really?"
I'm on a Mac/ OS10.6.8. I'm running a MOTU 2408mk3 as I/O between the D8B (v5.1) and the Mac via three OPT-8s. The D8B and the MOTU 2408 are externally clocked by a Symetrix Lucid GENx192. I have three DAWs. Primary is Cubase 6.5.1. Secondarys are LogicPro 9.1.7 and StudioOne2 v1.6.5. I own Ozone 4 and a little Bit analyzer by Schwa called "Bitter" It's AU only.
I ran some tests recording audio sourced from the D8B's Mic and Line preamps. Sent to the DAWs @ 44.1kHz/24bit.
Tried this on all three DAWs (Cubase can't run Bitter) and as far as I can see (with UV off across all 3 cards) I'm getting full 24bit recordings.
(1)With UV on and the Pre's at minimum gain, I can clearly see the last 8-9 bits (16-24) getting filled with dithering noise.
(2) With UV off nothing at minimum preamp gain.
(3) With UV off and a -2.5dbfs 1kHz tone on the way in, I get about 23bit registering.
So I have to ask: What are the settings on the RME? Can you post a screenshot?
I also get about the same thing in Bitter (in Logic and StudioOne) but the Mac version seems to have an entirely different UI than what you've posted.
Maybe it is a v3 issue. I dunno. I haven't used v3 since I started installing v5 betas when we were developing it.
