6. Operation and DSP Functions 

 
The 

ADI-96 PRO

's user interface is easy to understand thanks to its clearly structured 

front panel design. The big and bright 2 x 20 character LC-display plus a simple and straight 
cursor controlled menu structure will probably make you never look into this manual. Because 
of the numerous functions found in the 

ADI

 and its software, we strongly encourage you to 

study this manual. 
 
Let's start with a short introduction into the 

ADI-96 PRO

's user interface philosophy. 

 
After power-on and automatic calibration the Info window will come up and show the currently 
loaded DSP software. The device remembers all settings even without saving them. To be sure 
a certain setup is being used unaltered, you should first reload it using 

Recall

 (see 6.9 Setup). 

 

Press 

Enter

 to bring up the Overview window, which displays all configurations and the avail-

able DSP functions. Each function is represented by three letters, and is the highest menu of 
several submenus. 
 
On this level each function can be activated and de-activated (Bypass) using the +/- keys. 
That's why they are also labeled 

ON/OFF

. Below this row of functions two lines out of thin lines, 

fat lines and bars can be seen. These two lines represent one channel each. The state of each 
function is shown by a thin line (off) and a fat line (on). The screenshot below shows all func-
tions activated except LOC (Low Cut). A global bypass, useful for comparing the sound with 
and without DSP functions can be set by pressing the additional key 

Bypass DSP

 

 

 
To avoid pan shifts between left and right channel the control paths (sidechains) of some func-
tions can be linked. As shown in the above screenshot, 

Link

 is activated for the function EXP 

(Expander), because both channel rows are no longer separated, but combined by bars. The 
functions OUTPUT and SETUP can not be deactivated nor set up separately, so no lines are 
shown at all. INPUT can't be deactivated, but in the stereo version of the DSP software the 
channels are linked. 
 
To enter a sub menu first use the arrow keys to move the cursor (shown as a blinking of the 
corresponding three letters) in the desired direction. The Overview window will begin to scroll 
because not all functions can be displayed simultaneously. An arrow will show up at the left and 
right border of the display, indicating that some more functions are available (see picture 
above). The submenus are accessed by pressing 

Enter

, a second press on 

Enter

 jumps back to 

the Overview window. 
 
The button 

Meter Mode

 allows to switch the Peak Level Meter and the Correlator before (Input) 

or behind (Output) the DSP. This allows to check changes in level and phase caused by the 
activated functions without the need to switch the DSP in bypass mode. 
 
Scrolling through the values with the +/- keys becomes accelerated when pressing the buttons 
for a longer time. A jump to the highest or lowest possible value is done by first pressing one, 
then the other key additional. 
 
On the following pages you'll find detailed informations to all functions currently available in the 
factory shipped DSP software 

Dual Mono A/D
