1 – Overview
The unD4I and unD4I-L four input Dante interfaces are the ideal interface for adding mic/line inputs to a Dante system.
They come in a small form factor with integrated mounting bracket allowing it to be mounted discretely in small spaces
(such as under desks) close to the sources or sinks to reduce the amount of interference-prone analog cabling that .is
required.

Both the unD4I and unD4I-L feature four balanced mic/line inputs using 3-pin depluggable connectors for balanced or
unbalanced connectivity. Each input supports eight different gain levels from -12dB to +45dB. Each input also supports
a +48V phantom power option. Front panel indicators show each channel’s gain and phantom power status for easy
troubleshooting.
The unD4I and unD4I-L, can be powered by an ex24VDC power supply (ordered separately) but also support the
use of PoE. This allows them to be powered over the network cable from a suitable PoE source (IEEE 802.3af). The PoE
power option is particularly useful when mounting in a remote location where access to a mains outlet is limited or indeed,
non-existent.
Both product versions have two network connections to allow daisy chaining. Daisy chaining further simplifies system
infrastructure wiring by allowing multiple devices that support it to use a single CAT 5 home run connection to a network
switch. Power can also be daisy chained to additional devices that support power link connectors.
Audinate’s Dante Controller or other 3rd party manufacturer's Dante routing software can be used to control the audio
routing configuration of the device while the Attero Tech unIFY Control Panel application can be used to configure the
device-specific features.
