Topic: Balanced Phones Mode and Loss of Pass-Through Functionality
I currently have my ADI-2 Pro FS R BE hooked up as follows:
Music source device output connected to ADI-2 AES input, with SRC enabled
Digiface USB output connected to ADI-2 ADAT input
ADI-2 ADAT output connected to Digiface USB ADAT input
ADI-2 PH 3/4 TRS output connected to headphones
Dig Out Source is set to Main Out
Main Output AD/DA Source is set to AES
Phones Out 3/4 Source is set to SPDIF
With this configuration, the ADI-2 does double (simultaneous) duty: (1) SRC for AES music source, passed to TotalMix FX via ADAT; and (2) headphones DAC and preamp for separate input from TotalMix FX via ADAT.
However, when I enable Balanced Phones Mode, the signal from the AES input is no longer passed to TotalMix FX via the ADI-2's ADAT output. I can still direct any TotalMix FX channel to the headphones, and the ADI-2 is still showing an AES input signal present, but the the AES input no longer gets passed to the ADAT output for mixing by TotalMix FX (and return to the ADI-2 via its ADAT input).
Is there any solution to this routing problem? I understand that engaging Balanced Phones Mode necessarily disables the 1/2 analog outputs on the rear of the device, since the associated analog circuitry is needed for the right balanced headphone channel, but I don't why that should prevent a purely digital pass-through.
