6. Powering up / down
To switch on / off your DA 230, please follow the instructions:
1. Apply power supply connection (90 - 250 Volt / 50 - 60 Hz) on DA 230 (if the unit is
switched to power mode „Always On“, it is switched on now) – „lock“-function can be
active!
2. Press for a very short time the OK-button to switch on the DA 230
3. To switch off the DA 230, press for 1 second the left arrow key and than the OK-button.
If the unit is locked, please disconnect the power supply connection to switch off the
DA 230.
Note!
Switch on the DA 230 when all connected components are switched on and muted
previously to avoid an unwanted sound reproduction. As the DA 230 can be in „lock-
function“ for rental purposes, that means the unit may not react on changes on the control
panel (depending on adjustment before), this can cause an immediate reproduction when
switching it on. Therefore it is necessary to mute all connected devices previously.
During power on for the very first time, „Preset 1“ is loaded! More information about the
initial state you can find on page 3.
6.1 Choose your preset - play!
To adapt your completely digital 2-channel amplifier to your reinforcement system, you
have to choose and load the correct preset. For selected applications the DA 230
includes some pre-set presets. If you would choose these presets, please take care of the
internal routing of the signal inputs and speaker outputs of the DA 230 (provided that the
input signal is analogue).
The DA 230 includes 12 factory presets in the internal memory which can be free
programmed and saved on the actual preset. You can change and save the name of the
preset too. You can save and load factory presets also on SD-card. How to do that and
which changes are possible in the detailed submenu, you will find on page 8 - 10 in
this manual.
6.2 Selecting presets
In the following example you choose „preset 3“, please follow the instructions!

After powering up the DA 230 for the very first time the left graphic appears on the LCD display.
Now „preset 1“ is loaded. To choose and load for example „preset 3“ you have to press the
marked arrow key twice and confirm with the OK-button. If you control your PA system with an
analogue audio signal,
you can start now!
