Digital Through Mode - RME Audio ADI-2 Pro User Manual

17.5 Digital Through Mode

This additional mode is a manual option only, it is not available via Basic Mode Auto. It has to
be activated manually by selecting Basic Mode – Dig Thru.
The purpose of the Digital Through Monitor is exactly what its name describes. A single digital
input signal is passed through the unit and can be monitored on the analog outputs at the same
time. Automatic clock and source selection of the digital inputs plus internal D to D routing al-
lows to insert and monitor AES, SPDIF or ADAT signals. With ADAT only channels 1/2 are
monitored, but all 8 channels are passed through.
The digital signal is not simply patched from input to output, but completely rebuilt. It gets totally
refreshed by SteadyClock III, and even clock decoupled or up-/down sampled with the SRC
turned on. Without SRC the included 24 bit audio data is passed on bit-transparent.
As any digital input signal becomes available at all three digital outputs, Dig Thru mode also
offers digital format conversion as well as a distribution feature (one source to three destina-
tions).
Note: To simplify the diagram and to maintain overview USB record is not shown. In all modes
all input signals are sent over USB to the host. In multi-channel mode three separate stereo
pairs, in stereo mode only the stereo analog input.
USB Playback channels 3/4 can only be monitored in multi-channel mode. In stereo mode se-
lecting USB 3/4 plays channels 1/2.
