4.2 Operating modes
The M1.1 monaural power amplifier has two main operating modes: Normal mode and Menu mode. Normal mode is mainly used
to display the M1.1 general status (such as power or temperature) whereas the Menu mode is used to configure the unit. The M1.1
also includes Shortcuts to quickly access preselected Menu items. Shortcuts are user programmable and most Menu mode items can
be selected as Shortcuts.
4.2.1 Normal mode
In normal mode, the M1.1 can be configured to display its general status, such as operating mode (stereo/mono), input
(XLR/BNC/RCA), feedback ratio, peak power and internal temperature. It can also be set to display a peak power VU-meter, or a
temperature gauge for each output channel. Once powered-on, the M1.1 sits in Normal mode. The status display looks as follows:
