4.4.3 Access Level
The DS50 has the option of locking away the front panel controls to avoid tampering of
settings by unauthorized persons. When switching on the DS50 for the first time all the
functions are locked.
To enable operation of the control panel you first need to unlock the DS50. To unlock
the DS50 control panel Press the MENU button, rotate the SELECT button (encoder)
counterclockwise until the display shows Unlocked. Press the SELECT button and the
system will ask you to enter a password. Select a character in the cursor position by
the rotary encoder: pushing the rotary encoder confirms the character selected and moves
the cursor to the next character to edit. Pushing the exit/ESC button erases the last confirmed
character. The Password is automatically checked after each entered character, and will exit
the system menu when the right password has been entered. The default password is
“SA“.
To lock the DS50 control panel Press the MENU button for 3 times, and the display wil
show Acces level: Unlocked. Rotate the SELECT button (encoder) clockwise to Locked and
press the SELECT button. The system will show you the last used password. You are free
to use this or change it to another password by rotating and pressing the SELECT button. Press
MENU twice to confirm and set the password.
ATTENTION:
Make sure to remember the password! When the unit is locked and you forgot
the password, it is not possible to unlock it without contacting your local service representative.
4.4.4 Version Information

rotary encoder, the display toggles through some version information about the unit as well
as some parameters like IP address, MAC address etc.
4.5 Indicators
Each channel of the amplifier is equipped with the following indicators:
Power Amp On: These LEDs will light when the power amp of the related channel is
switched on and the electronic circuits are stable. In case of an error in power supply or
main stage the LED will blink or swithes off. In that case the amplifier is damaged and
should be repaired by an authorised Stage Accompany service center.
Signal present: these LEDs will light when a input level of more than 40 dB under the
level that would cause maximum power is detected. The signal present LEDs work
dependently of the settings of in- and output of the DSP settings. These LED
’s indicates
the present of input signal at the power amp stages.
Clip: this LED will light when the output level of the amplifier has reached its limit. The
indication is correct for every connected impedance. When the clip LEDs flash fre-
quently, distortion is to be expected.
