Lectrosonics DNT22 Data Sheet

DNT22

Dante™ 2 IN/2 OUT I/O Interface

• Small form factor, can be unobtrusively
located near analog sources or sinks

• Dual power (DC or PoE) means the DIO2x2
will work in systems with either standard or
PoE Ethernet switches

• Three input gains accommodate common line
levels, phantom power and dynamic mics

• +24V Phantom power per channel - powers
virtually all types of phantom powered
microphones typically used in installed AV
systems

• Two analog output gains to accommodate
both consumer and pro line level
requirements without overload

TECHNICAL DATA

The DNT22 I/O Interface is a 2in/2out, cost-effective way
to add up to two channels (in and out) of Dante™ audio
to an existing Dante-based networked audio system.
The DNT22’s small form factor and PoE power capabil­ity make it easy to put Dante connectivity wherever it’s
needed - near the audio source or sink thereby eliminat­ing costly and interference prone analog wiring.

DIO2x2 Rear Panel Connections

DC Power Input - +12VDC @ 500mA. No DC power
is required if the DIO2x2 is used with a PoE Ethernet
switch.

Dante/PoE Network Connection - 100 Base-T Dante
Ethernet network connection.

Balanced Mic/Line Inputs - RF protected balanced
mic/line input. +24V Phantom (switchable via software
individually for each channel). Gains of 0dB, +25dB, and
+40dB are available (switchable via software individually
for each channel).

Balanced Line Outputs - Low impedance (200 ohms
balanced, 100 ohms unbalanced) balanced analog out­puts. Analog output gains of 0dB and +10dB are avail­able (switchable via software individually for
each channel).
