9. Operation and Usage

General operation and usage of the ADI-2 Pro are explained in chapter 5.2, Quick Start, and
chapter 5.3, Operation at the unit.
The ADI-2 Pro ships with Basic Mode Auto activated. In this mode the unit will automatically
reconfigure itself depending on the connected cables, offering quick, easy and intuitive opera-
tion:
No digital input, no USB = Preamp mode
Digital input signal = AD/DA converter mode
USB connected = USB mode (USB interface or USB DAC operation)
These modes are explained in detail in chapter 17. The current mode is also shown for 2 sec-
onds (Info Message) whenever it changes, and one time after power-on.
State Overview is especially useful to check the state of digital input signals as well as the cur-
rent settings with USB. It also displays several warning messages which might explain why
currently no sound is audible. See chapter 15.3 for details.
The following chapters explain all the controls and menu items in detail.

10. Front Panel Controls

10.1 Keys

The four back-lit keys offer quick access of important parameters within the menu structure.
After pressing one of the four keys the corresponding menu is shown in the display. The unit
remembers the last selection per key, so re-visiting a formerly changed parameter is easy. To
leave the menu push the same key a second time, or any other key two times. The display will
revert to the level meter screen that was active before entering the menu.

10.2 Encoders

The encoders can be turned endlessly, but also pressed, adding a push button function. The
current functionality of all encoders is shown in the display. The big Volume knob usually con-
trols volume for outputs 1/2 or 3/4. The current assignment is indicated in the display's status
bar by a marker around the volume value.
Turning the small encoders 1 and 2 either changes the current parameter, or moves the selec-
tion/cursor horizontally to the next page. Pressing the encoders 1 and 2 moves the selec-
tion/cursor vertically, up with 1 and down with 2, as indicated by the arrows in the display.
Example: Press the key SETUP. The menu Setups is now
shown. 1 within the circle on the right side indicates that by
turning encoder 1 more pages are available. Turn encoder
1 left to enter Options. Now turn encoder 2 to scroll
horizontally through all the subpages offered under Op-
tions: Hardware/Diagnosis, Device Mode, Clock. By
pressing encoder 2 the cursor moves down, by pressing
encoder 1 back up. On a selected field or entry, 2 to the
right indicates that the current parameter can be changed
by turning encoder 2. Change Clock Source and Sample
Rate to see how easy it is to select and change important
settings.
