Stealth mode
The d:series amplifier offers an option to switch off the display. For example, in case of usage in the dark,
where the display light would disturb the environment. Select the ‘enable’-button on the right to switch
off. It can be activated by pressing anywhere on the screen.
Note: If the screen is not touched for a certain time, it will be dimmed automatically.
Fan mode
The d:series amplifier provides five different fan modes: low, normal, high, linear, silent. By default, the fan
mode at startup of the amplifier is set to ‘normal’. Selected other modes are just activated until the device
is shut down.
low, normal, high
The fan modes ‘low’, ‘normal’ and ‘high’ enable static fan speeds until the temperature exceeds a
predefined limit. If the predefined limit is reached, the fan speed will be ramped up according to the
measured temperature. A detailed performance information can be found in the graphic below.
linear
By selecting the linear fan mode, the fan speed will be set according to the measured temperature.
silent
In silent mode, the fans slow down to minimize ventilation noise.
In case the amplifier heats up to a predefined maximum temperature (as shown in the graphic below), the
fans accelerate to cool the circuits down to normal working conditions.
