8.7 Configuration and operation
8.7.1 Introduction
The next sections give descriptions of the possible
configuration options. Each description is followed by
the relevant menu items with detailed instructions per
menu option. The default values are indicated by an
asterisk (*) when applicable.
8.7.2 Start-up
When the power amplifier is (re)started, the display
shows the name of the unit and the VU meters for the
outputs. If it shows Load Unit Software, the unit does not
contain any firmware or old firmware. By default, it is
delivered without firmware. See section 36.5 for
information about upgrading the firmware.
8.7.3 Status screen
The Status screen (see figure 8.18) shows the name of the
power amplifier and provides general information about
its (fault) status (see table 8.7). If there is more than one
active fault, only the most severe fault is shown. A fault
status only provides global information. The exact
source of a fault can be found out using the fault events
list in this manual (see chapter 54).
