Display Mode:
Output headroom
[headroom display]
Input levels
[input level display]
Diagnostics
[operation display]
You can chose between three layouts of the LCD display. The first one shows the headroom of
all 4 amplifier modules. The second one gives an overview about input level (with 0 dB level).
The third one informs you about the temperature of the amplifier module and the PSU
(PowerSupplyUnit) as well as the actually mains voltage of DA 428.

LED Settings:
Signal LED Threshold
[adjustable per channel]
User LED Threshold
[adjustable per channel]
Here you can set the threshold value where the LED starts to light green when the set value is
reached by the audio signal. It is only an optically notice.
Here you can set the threshold value where the LED starts to light blue when the set value is
reached by the audio signal. This function allows you to set an optical limit for the volume level
for your audience, e.g. -6 dB – you know your pre-set value is reached.

Power Management:
Mode: Always On
[after apply power supply connection the DA 428 is switched on]
Last State
[DA 428 starts in the last state of operating]
Audio Trigger
[depending on the input level the DA 428 switched automatically
on or off]
Trigger Level
[enter threshold value for Trigger Time – valid for all channels]
Trigger Time
[adjust remaining On-time]
In this menu item you can pre-set the operating status of the DA 428:
If you choose „Always On“, the DA 428 is always on. That means after apply power supply
connection the unit is automatically on and ready to play (the “lock function” can be active!).
If you choose „Last State“- mode, the DA 428 will always start in the last state of operating after
power cycle the unit.
To reduce the power consumption e.g. in installations you can choose the „Audio Trigger“-
mode. In this mode you can set a threshold value and a time value where the system
automatically switched off when the threshold is not exceeded with an audio signal. After the
pre-set time the unit is switched off. If the pre-set threshold value is exceeded during the unit is
still on, the time value counts again - that means this function is a posttrigger-function. You can
switch on the unit again by pressing the OK-button or playing an audio signal which has a
higher input level as the pre-set threshold value. Trigger source for the pre-set time value is
every channel.
