3.6. Analog Input Connectors
XLR/TRS combo jacks 1-4
On the front of the device, four combined XLR/TRS inputs labeled "1" to "4" can be used for microphone,
line and instrument signals. Phantom power (48 V) for microphones can be activated on each XLR input,
high impedance ("Hi-Z") can be activated when using unbalanced TS connectors. Both XLR and TRS
jacks accept balanced signals and maintain full symmetry internally all the way to the A/D converter.
Phantom power is not applied at the TRS inputs.
