17.3 AD/DA Converter

AD/DA: Converter Mode, analog in to all digital outs, digital in to all analog outs.

This mode can be activated manually by selecting Basic Mode – AD/DA. The device enters

AD/DA mode automatically when Basic Mode is set to Auto and a digital input signal is de-

tected.

The detected digital input signal will also become the signal source. In case more than one digi-

tal signal is found the user has to manually select the source to be monitored (I/O – Output

Channel - Settings – Source). The SRC is active by default, assigned to SPDIF, but switched off

automatically if a DoP signal (DSD) is detected. Clock mode is slave to AES in, but will adapt to

the detected source (Auto).

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.

The option Digital Out Source - Main Out (SETUP – Options – Device Mode / DSD) sends the

processed signal Main Out 1/2 to the digital outputs AES, SPDIF and ADAT, for example to

connect active monitors having digital inputs.
