Input Level and Gain LED Stack — The LED stack displays the input signal level of the selected input from no signal to
E
-60 dBFS (first LED lit) up to 0 dBFS (all LEDs lit). When the gain rotary encoder is rotated, the LED stack changes to display
the input gain level of the selected input. Input gain level continues to display for 3 seconds after adjustment of the rotary
encoder ceases. After this 3 second period, the LED stack displays the input signal level.
The dB scale to the left of the LEDs indicates input gain level from 0 dB to +42 dB. Gain adjustments are made in 3 dB steps
and each LED represents 6 dB of gain. The LED blinks to indicate a 3 dB gain change, and lights steadily to indicate a 6 dB
change. For example, when the LED next to 6 dB blinks, 3 dB of gain is applied. When the LED next to 6dB lights steadily, 6
dB of gain is applied.
Gain Rotary Encoder — The rotary encoder adjusts the input gain for the currently selected input from 0 dB to +42 dB in
F
3dB steps. Using a small flat head screwdriver such as the provided Extron Tweeker, turn the encoder clockwise to raise the
gain and counter-clockwise to lower the gain.
Phantom Power Switch — This momentary switch turns 48 V phantom power on and off for the currently selected input.
G
Using a small flat head screwdriver such as the provided Extron Tweeker, push the switch up to turn phantom power on and
down to turn it off. The switch is neutral in the middle position (default).
Phantom Power Indicator LEDs —These green LEDs light steadily to indicate which channels have phantom power
H
applied.
Input and Output Signal and Clip LEDs — The green signal LEDs light steadily when signal is present and increase in
I
intensity from -60dBFS (lowest intensity, signal presence indication) to -1 dBFS (full brightness). The red clip LEDs light
steadily when signal exceeds -1dBFS to indicate clipping and stay lit for one second beyond receiving the clip message. The
output signal and clip LEDs reflect pre-attenuation levels.

Dante Network Setup
Use a standard Ethernet cable to connect the AXI to a network via the RJ-45 AT (PoE) port (see figure 1, D on page1) and
power the device. Launch the Dante Controller program.
Dante Controller auto-discovers all Dante devices on the network and advertises itself to allow other Dante-enabled devices to
communicate with it. The default device name is the model name followed by the last six characters of the device MAC address.
Multiple devices on the same network can present difculty in identifying inputs and outputs. To avoid confusion, rename each
device to a unique and meaningful identier.
NOTE: To simplify setup, connect only one Dante device to the network at a time.
Finding a Dante Device IP Address
To nd the IP address of a Dante device, the name of the device needs to be known (see Naming the AXI 22 AT and AXI 44 AT
on page5).
NOTE: If the AXI has not been renamed, its default name consists of the product name followed by a hyphen (AXI22-) plus
the last 6 characters of the device MAC address (for example, AXI22-0744c1). Obtain the media access code (MAC)
address of the desired device from the white label on the rear panel of the device.
1. Open Dante Controller.
2. On the Dante Controller Network-View screen, click the DeviceInfo tab (see gure 8,
3. On the DeviceInfo page, locate the name of the AXI (
example below, the IP address for the connected AXI 44 AT is 192.168.11.181.
). The IP address is in the PrimaryAddress column (3). In the

Dante Operation
Dante Transmitters and Receivers
A Dante network is comprised of transmitters that output digital audio onto the Dante network and receivers that receive digital
audio from the Dante network.
The AXI 22 AT and AXI 44 AT mic/line inputs are Dante transmitters because the analog audio input is converted into digital audio
and transmitted onto the Dante network.
The AXI 22 AT and AXI 44 AT analog outputs are Dante receivers because they receive digital audio from the Dante network and
output that signal as analog audio via the line outputs.
Network View Layout
Dante transmitters are listed horizontally across the top of the
Network View window (see 1 in the gure to the right), while
Dante receivers are listed vertically on the left side of the window(2).
Creating a link in the connection matrix (3) routes audio from a
Dante transmitter to a Dante receiver.
Routing Transmitters and Receivers
1. Click the + box next to the device with the desired Dante
transmitters (AXI44AT-ConfRm1 in the example to the right).
The available transmitters display horizontally.
2. Click the + box next to the device with the desired Dante
receivers (DMP128PlusRackTopEXP_IN-01 in the example to
the right). The available receivers display vertically.
3. Click the junction of the desired connection in the connection
matrix.
Example: AXI44-ConfRm1 Mic/Line In 1 to
DMP128PlusRackTop EXP_IN-01 (shown to the right).
A green check mark at the junction indicates the connection is
made. A check mark is also placed next to the receiver channel
(if a green check mark does not appear, refer to the Dante Controller section of the AXI 22 AT and AXI 44 AT User Guide).
NOTE: A transmitter can transmit signal to multiple
receivers, but a receiver can only receive signal from
one transmitter.
4. Click the junction again to disconnect the transmitter from the
receiver.
Additional transmitters and receivers can be connected or disconnected using steps 1 through 4 as shown above (for additional
information on Dante Controller operation, see the Dante Controller section of the AXI22 AT and AXI 44 AT User Guide at
