12.4.4 Audio outputs
You can connect external digital audio devices to the
audio outputs of the digital audio expander. The digital
audio expander has two audio outputs (refer to figure
12.6). Each audio output has:
• 1 XLR plug for AES/EBU signals. The electric
circuits behind the XLR plugs contain transformers.
• 1 cinch socket for SPDIF signals.
Note
You cannot use the AES/EBU and SPDIF
connections of the same audio output at the
same time.
