Chapter 6: Troubleshooting

The Linear Acoustic AERO.one is a very stable and reliable unit, and most problems can
be traced back to mis-wiring causing incorrect signals to be applied to the unit, or more
than likely mis-configuration. As simple as the unit is to use once installed, it is very flexible
and thus a necessarily complex processor. In an effort to speed troubleshooting, some
common problems and solutions are described below.
6.1

Problems and Possible Causes

One of the best troubleshooting features of the AERO.one is the hard-bypass of the audio
signals. This is useful because it allows instant removal of the unit from the signal path.
Hard-bypass can be accomplished two ways, the simplest being to remove AC power from
the unit by turning the power switch off. A less dramatic way to accomplish the same result
is to access the I/O menu and enable Master Bypass. If you are unsure of what is happen-
ing in a particular system, simplifying the signal path is a good start and will help isolate
problems quickly.
6.1.1

Unit won't power on

First check the obvious and make sure that the power cord or cords are plugged into live
AC outlets (it happens). Next, see if either or both of the blue front panel PSU lights is
illuminated. If not, check the power supply fuses by removing the power cords and using
a small flat-blade screwdriver to remove the fuse holder from the IEC inlet module. The
holder carries a spare fuse and extras were included in the packing kit with the unit. If the
fuse is bad and continues to blow, please contact the factory.
6.1.2

The Ref LED is red

Check to make sure that an AES reference signal is connected to the unit and that the cor-
rect reference is selected. Note that this signal can be either AES black (i.e. an AES signal
with silent audio), or an AES signal with audio. Reference can be derived from Main Input
1, Input 4, SDI, or Internal within the I/O Options menu (see Chapter 4).
