E Input Level and Gain LED Stack — The LED stack displays the input signal level of the selected input from no signal to
-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 6 dB lights steadily, 6
dB of gain is applied.
F Gain Rotary Encoder — The rotary encoder adjusts the input gain for the currently selected input from 0 dB to +42 dB in
3 dB 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.
G Phantom Power Switch — This momentary switch turns 48 V phantom power on and off for the currently selected input.
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).
H Phantom Power Indicator LEDs —These green LEDs light steadily to indicate which channels have phantom power
applied.
I Input and Output Signal and Clip LEDs — The green signal LEDs light steadily when signal is present and increase in
intensity from -60 dBFS (lowest intensity, signal presence indication) to -1 dBFS (full brightness). The red clip LEDs light
steadily when signal exceeds -1 dBFS to indicate clipping and stay lit for one second beyond receiving the clip message. The
output signal and clip LEDs reflect pre-attenuation levels.
DSP Configurator Software Installation
In addition to the front panel controls, the AXI 22 AT and AXI 44 AT can be controlled with Extron DSP Configurator software using
the USB or AT ports, or DataViewer using the USB port. Install DSP Configurator on a PC running Microsoft
computer requirements, see the DSP Configurator product page on www.extron.com.

AXI 22 AT and AXI 44 AT Configuration
Configuring the AXI 22 AT and AXI 44 AT
Ensure the host computer is connected to
1.
the AT port or front panel USB Config port.
Start the DSP Configurator software.
2.
From the splash screen drop-down, select the
3.
AXI model corresponding to the model connected to
the control computer.
Click OK and the main workspace opens.
4.
The software starts in Emulate mode.
5.
To create a configuration file offline and
a.
upload (push) that configuration to the device at a later time, remain in Emulate mode.
To push a configuration to the device or pull the current configuration from the device, enter Live mode. When in Live
b.
mode, changes made in DSP Configurator affect the connected device immediately. To enter Live mode, click Live
at the top of the DSP Configurator workspace. Alternatively, select Tools > Connect to Device or press <F6> on
the keyboard. When Live mode is selected, a connection dialog box appears. Select the desired connection type and
follow the on screen prompts (see the AXI 22 AT and AXI 44 AT User Guide for more information on connecting Live to a
device).
