General setup >> Input gain
The gain for each individual input can be set in this
screen between a range of -16.5 dB and +30.75 dB.
After scrolling and selecting the right input, gain can be
adjusted through turning the rotary selection dial. Level
indicators are shown on the right side of the display
indicating the correct set gain level. Three color digits
(green, orange and red) will illuminate at different levels
and give feedback about the currently set gain. A correct
regulation of the input gain is achieved when the green
indicator is frequently blinking, the yellow indicator is only
illuminated at the peaks (-6 dB) and the red indicator
blinks rarely or not. When the red indicator blinks
frequently, the input is over driven and the gain needs
to be reduced. When the green indicator blinks rarely or
not, no input signal is detected and the gain needs to be
increased.
General setup >> Password
Password protection is provided in two different levels, administrator and user level.
Administrator level has full access to all available functions of the amplifier while user level
only can access the volume of the amplifier. Both passwords consist of a 4 digit code which
is intended to be different.
In standard configuration, both passwords are set to ‘0000’. In this case, full access is given
without requiring any password. If either the configured user or administrator password is
different from ‘0000’, a password will be requested before access to the relevant functions
is provided.
The configuration of the selected password can be made by selecting Admin pass or User
pass in the column on the left side. The currently selected password will be shown and the
adjusting digit can be selected (turns red) and confirmed by turning and pressing the rotary
selection dial. Consecutive digits will increase when the maximum value has been reached.
After the desired password has been selected it can be confirmed by pressing (turns red) and
turning the function dial clockwise to the entire right side where the ‘OK’ word will appear.
After pressing again the password is confirmed.
General setup >> LCD
Adjustment for the LCD settings can be made in this screen. The brightness of the LCD
can be adjusted within a range of 10% to 100% (standard is 80%). Adjusting of the LCD
brightness can be convenient when the device is placed in an environment with very low
or very high ambient light. Hereby the clarity of the LCD can be adjusted in such way being
clearly but unobtrusive.
The backlight off time can be adjusted within a period of 5 up to 120 minutes in steps of 5
minutes or never (always on), making the backlight of the LCD automatically turn off after
