11User Interface Tutorial – Input Source Selection and Peak Level SettingThe following two exercises are a useful introduction to the user interface. Start from the Main Menu (as displayedwhen the unit is first turned on).The first exercise changes a parameter selection (the Input Source selection): Rotate the jog-wheel to highlight Input/Output. Click the jog-wheel (push on the wheel once until a click is felt and release) to bring up the Input/Outputmenu. Rotate the jog-wheel to highlight Input and click. Rotate the jog-wheel to highlight Input Src and click. The factory default selection for Input Source is Analog. To change the input selection to AES/EBU digitalor Livewire, rotate the jog-wheel until [AES/EBU] or [Livewire] is displayed and click. If you are usingthe analog inputs, rotate the jog wheel to display [Analog] and click to reselect the analog inputs. To return to the top level of the Main Menu, rotate the jog-wheel to highlight <-EXIT and click. Repeatuntil the top level (Main Menu) is reached. NOTE: Many of the Omnia ONE’s menus have an <-EXITselection at both the top and bottom of the menu.The next exercise adjusts a parameter that uses a value (the analog master input level setting): The Main Menu display should still be showing on the LCD screen. If not, click the jog-wheel to display it. Highlight Input/Output and click. Highlight Mtr Select, click, rotate the jog wheel until [Input] is displayed and click. This sets the first 2 LEDmeters to monitor the Left and Right channel input levels. Rotate the jog wheel clockwise to highlight Input and click. Rotate the jog wheel to highlight Anlg Level and click the jog-wheel to select the control. Rotate the jog-wheel CW to increase the input level. Rotate the jog-wheel CCW to decrease the input level.This control adjusts both channels together in precise 0.5 dB steps. The gain in dB is shown to the right of the“control.” Watch the Left and Right channel LED meters while adjusting per the following section below.Proper Setting of Input LevelsWith normal program audio levels applied, a correct input level setting will result in peak indications on the L & RLED meters achieving –12 dBFS or a little higher (just into the yellow). This gain setting corresponds to systemheadroom of about 12 dB. You may adjust the input level lower for more headroom if you wish. Setting the inputlevel for higher meter indications (less headroom) is strongly discouraged unless there is another level-controldevice prior to the Omnia ONE that will keep the input levels from reaching the maximum digital level of 0 dBFS.During normal operation, you should never see the red “0” segments light. Once the desired level setting is reached, click the jog-wheel to accept that value. This returns the jog-wheelto Select Mode. You may highlight and click Right Trim to adjust its gain separately from the left channel if the input sourceis not well balanced. In this mode the right channel gain can be adjusted over a range of plus and minus 3 dB |
