AMP PRESET - Load – using the arrow symbols, select a preset from the amp preset library and load it by clicking on LOAD
SEND – Transfer an amp preset to the power amplifier's memory and load it
– reset the settings in the amp preset to start creation of a new amp preset. The previously loaded amp preset
– load an amp preset from the PC memory.
– save an amp preset to the PC memory.
30
READ CURRENT – synchronize the currently loaded amp preset with the software.

INPUT SIGNAL – (DSP44K only) click on the popup menu to select either physical analogue signal inputs (XLR) or DANTE (RJ45).
The setting affects inputs 1 and 2 or 3 and 4. The setting will not be saved in an amp preset.
INPUT LEVEL – level displays for inputs 1 to 4.

smoothly by the integrated limiter. If the CLIP indicator remains lit for longer or permanently, reduce the

regulates the main power amplifier parameters (signal input, load, temperature, current) in order to draw
only the required current from the power supply for safe operation. The PMS display illuminates in the
following situations:
1 If, due to unfavourable working conditions, the internal temperature increases and approaches the
threshold level at which the automatic switch off function will be activated to avoid overheating of the
system. In this case the system takes control and reduces the power to a level at which the power stage
is not switched off.
2 In the event of excessive power consumption. This situation occurs exclusively under laboratory
conditions in long-term tests with sinusoidal audio signals and dummy loads or in ongoing acoustic
feedback conditions. Here, the PMS system intervenes to avoid damage to the speakers and to prevent
triggering of the main circuit breaker or blowing of the electrical fuses.
