Figure 4.2
All channels have 3 possible inputs, use one of these inputs to connect a microphone or a line-level source. The
XLR and DIN input are balanced, the stereo Cinch input is unbalanced and converted to mono. If you use an input
make sure that the internal switch settings are correct (refer to §2.2).
Note
If you want to use the priority feature, you must use a microphone or line-level source with a priority contact
on pin 4 and 5 of the 5-pole DIN plug.
