Reply to Xone DB4 Digital Output/Volume Control Issue, Please Help

Hello out there,

I am using
2x CDJ 2000 connected to Xone DB4 using SPDIF cables. I am using the master out XLR (from DB4) to TRS on an Apogee Ensemble. Running Mac Pro 10.7.5, Ableton 8.3.4, Maestro 2.5.57.
The digital source (same for both configurations) is AIFF files in RekordBox on the same MacPro connected via ethernet router.

Everything works perfect in that configuration. I just realized that I should simply use the digital output of my DB4 and run a SPDIF cable directly to the Ensemble instead, to avoid unnecessary D/A, A/D conversions.

I tried to run the SPDIF cable from the DB4 "Digital Record Out" to the SPDIF IN (Ensemble) and it works with the exception of the master volume on the DB4. The master volume (DB4) does not do anything to the level of the Digital Record Out (SPDIF). The gain and channel fader work, just not the master volume. It is "set by default" at a reasonably loud level and is not effected by the master volume control on the DB4.

I checked the "Record Out" settings in the menu of the DB4 and tried all available options (mix, clean feed, phones), same condition in all 3, everything works but the master volume (headphone volume in the case of phones setting)of the DB4. I tried to install the firmware update on the DB4 and still nothing. Contacted A&H and still nothing.

I love the idea of skipping the unneeded steps of D/A, A/D conversion and keeping it all digital. I would really like to make use of this digital output feature but the master volume is needed. It's killing me softly.

Can anybody out there help or point me in the direction of help in some way?

Also, while I'm here, does anyone know where to find information on the new features of the DB4 firmware update? I am very interested in "Cascade Mode" but can't seem to find it anywhere in the DB4 settings or info online about it. Thanks a ton for taking the time to read this. Have a great day.
