dB TECHNOLOGIES AC26N - Manual (Page 15)

Atten. Pad
It shows how to set the -6 dB switch located on the rear side [Ref. 5]. It is necessary to
activate this selector when the analog input levels are too high. The selector can be
activated only by means of the button; the menu is for display only.
0 dB = Selector not activated.
The input signals are the same as the input source
-6 dB = Selector activated.
The input signals are attenuated by -6 dB with reference to the inner
processor
Contrast
Allows to adjust the LCD display contrast to compensate for the brightness difference at
the installation sites. Greater display brightness allows to navigate correctly and quickly
within the menu.
The manufacturer output setting is 60%
10% More bright 60% More dark 100%
