7.4 On screen messages
7.4.1 Start-up sequence
When the controller is switched on it goes thru a start-up sequence and the LCD shows the 5 following on screen
messages:
The first on screen message indicates that all LEDs will be lit momentarily for
testing purposes.
The second on screen message displays the type of L-ACOUSTICS current
amplified controller and the onboard preset library version.
The third on screen message displays the version of the display firmware of the
current controller.
The fourth on screen message displays the IP address and the Serial Number
(or MAC address) of the current controller.
The fifth on screen message indicates the end of the start-up sequence and that no
fault has been detected.
7.4.2 Warning messages
If a malfunction of the amplified controller is detected a blinking warning message will appear on the LCD screen. As it
stands, 5 warning messages can be displayed:
Appears when the temperature of one of the 4 amp channel heat sink reaches
85°C, the input signal going into all amp channels is attenuated (see section 7.6.1).
Appears when a persistent DC voltage of plus or minus 3V is detected at one of
the amplifier output circuit (see section 7.6.2).
Appears when a power related fault is detected by the DSP whether its cause is
due to internal or external factors (see sections 7.6.3 to 7.6.5).
Appears when the main input current draw is too high and indicates that the fuse
protection feature is activated (see section 7.6.6).
Appears when the DSP and the Linux operating system do not talk to each other
(see section 7.6.7).
