Taken from Website and manual. I know most manuals are tedious But taking a few minutes to peruse yours may save you some trouble in the future!!!
On the faceplate of the DAC50x-4ch you can use the LCD which is a touch screen and the rotary knob to operate with the DAC50x-4ch. Tap on the LCD at the:
-
Upper left: input selection. The UPnP selection selects the Ethernet interface as the input.
-
Upper middle: output select. Only the selected output is active, i.e. XLR/RCA or JACK. The output which is not selected will be muted.
The displayed red icon also shows the output’s selected Output Termination.
-
Upper right: volume. If red then the output is muted. By tapping the output is toggled between muted and unmuted. The volume can be changed with the rotary knob.
If the value shown is yellow then the absolute polarity of the output is inverted (see below). All param- eters can be different between XLR/RCA output and JACK output.
-
Lower left: DSP settings. This opens a menu which allows to select one of the DSP algorithms to be changed. (Note, the rotary knob allows to scroll through the menus).
The algorithms can be operated via the touch screen, but we recommend to use the web interface (sec- tion 2.3) for simpler operation of the DSP features. All parameters can be different between XLR/RCA output and JACK output. Thus select the appropriate output first (XLR/RCA or JACK) and then adjust the DSP parameters.
