AVN-DIO12 Handbook
4
The
AVN-DIO12
is a dual microphone input to Dante converter with
adjustable mic gain in the Sonifex DIO range of Dante input/output devices.
It features 2 balanced analogue XLR inputs and one Neutrik etherCON
connector for direct connec�on to a Dante AoIP network. Each mic can be
routed via Dante Controller to any Dante receiver.
It’s powered using Power over Ethernet (PoE), using a Neutrik etherCON
connector for power and data redundancy. The AVN-DIO12 uses the latest
Audinate Dante chipset so is AES67 and Dante Domain Manager compliant.
Gain Adjustment
The AVN-DIO012 has coarse and fine mic gain for each microphone input.
The coarse gain is set using the toggle switch, which provides 20dB/50dB of
gain. The fine gain can be set using a trimmer adjustment tool, or small flat
blade screwdriver, and adds between 0dB and 36dB of addi�onal gain.
High Pass Filter
Each microphone input has an on/off toggle switch which turns the high
pass filter on or off. When enabled, it acts on frequencies below 125Hz at a
roll-off of 6dB/octave.
Phantom Power
Phantom power is enabled/disabled via a toggle switch on the front panel
for each microphone input. When enabled, a 48V DC supply is provided to
power an appropriate microphone. The red LED next to each input will
illuminate to indicate phantom power is enabled.
Audio Level LED
To help you set the mic gain, a level LED is provided on the front panel for
each microphone input to display the audio level being sent to the Dante
network. The indicator thresholds are as follows:
• Off: Level is under -38dBFS (-20dBu)
• Green: Level is between -38dBFS (-20dBu) and -18dBFS (0dBu)
• Amber: Level is between -18dBFS (0dBu) and -10dBFS (+8dBu)
• Red: Level is above -10dBFS (+8dBu)
Note: when using a phantom powered microphone, it may be necessary to
earth the unit using the rear panel earth tag to eliminate mains hum.
AVN-DIO12 Dual Microphone Input
to Dante® with Mic Gain Converter
Setup
First connect microphones to the mic inputs this will allow them to be
transmi�ed over the Dante network.
Connect the device to a PoE enabled switch using an Ethernet cable, the
device will automa�cally turn on. If the switch does not support PoE, a PoE
injector can be used to provide power.
By default the Dante IP address is obtained automa�cally, therefore the
device will automa�cally appear in Dante Controller. If your device does not
appear in Dante Controller please see the Network Troubleshoo�ng sec�on
of this manual.
A computer on the same network can configure connec�ons between the
DIO and other Dante enabled devices, using Dante Controller.
Link
Link status is indicated using the top-le� status LED. Once power has been
supplied to the unit the link status LED turns red. The link status LED turns
amber when a link is established with a link speed of 100 Mbps.
Link ac�vity is indicated using the top-right status LED which blinks when
incoming or outgoing data is sensed on the port.

Dante Controller
Once a link has been established Dante Controller can be used to configure
the device. Dante Controller is an applica�on provided by Audinate and can
be downloaded from their website.
Within Dante Controller the unit should be visible within the Rou�ng tab.
