Basic Setup
Basic setup and adjustment can be accomplished using the front panel GUI Lite
and its tabbed menu structure. There are seven tabbed options across the top of
the control area:
Input, Output, Encoder, Presets, Analysis, System, and Sound
.
Each tabbed menu contains the controls required to install AirAura and get it on
the air.
Install AirAura in the equipment rack using at least two rack screws. If only
two screws are used they
must
be installed in the bottom holes of the rack
ears to prevent undue stress on the front panel and possible bending.
Connect local AC power to the unit. There is no power switch and power is
applied to the unit as soon as you connect it to a suitable source of power.
The power supply is universal and accepts line voltages from 90V AC/DC to
260V AC/DC, 50 or 60Hz if AC. Power consumption is 64VA.
Connect the Analog or Digital audio inputs as appropriate for your installation.
Click on the Input Menu tab on the front panel GUI and select the input
source to match the Input type connected to the rear panel. If the audio
source is already providing an audio feed you should see meter activity on the
AirAura’s metering display.
While still in the Input menu and observing the Input meters adjust the Input
Gain control (AES or Analog as required) until the input meters are just
peaking around -12dBFS with normal program levels being applied.
Note that for best overall audio chain performance, the Input of the AirAura
should be calibrated so that it reaches 0dBFS when the signal chain prior to
the AirAura also reaches 0dBFS, or digital full scale.
Now make the audio output connections as appropriate for your installation,
noting that Analog and Digital outputs may be used simultaneously.
