8.7.1Introduction

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.

8.7.2Start-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.

8.7.3Status 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).
