System details

Front panel
- Gain and phantom power status LEDs : Shows the gain/pad setting and phantom power status for each of the four input channels.
- Power/ID LED : Indicates power when the unit is on, and blinks in response to a software command for unit identification

Rear panel
- Mic/line inputs 1 ~ 4 : Balanced and RF filtered inputs. Software selectable gain presets:
            without pad: 0dB, +15dB, +30dB, +45dB
            with pad: -12dB, +3dB, +18dB, and +33dB
            +48V phantom power on each channel
- RJ-45 ethernet connectors : The left RJ-45 connects to an Ethernet switch(PoE or non-PoE) and also provides the DC input for daisy chained units.
              the right RJ-45 provides DC out to daisy chained units.
- +24V DC input : Allows the unD4I-L to be powered
        if a PoE ethernet switch is not used.
- Power link in/out : Allows DC power to be daisy chained between multiple units.
- Logic inputs 1 ~ 4 : Allows external contact closures to be sensed and UDP, messages to be triggered to external devices.
- Logic outputs 1 ~ 4 : Allows LEDs and other low current devices to be driven, based on UDP messages from external devices.
