Using the menu system 
 

Any menu item without > next to it is a selection. Just highlight the required line and 

press ‘select’ to jump to the function. 

Any menu item with a > next to it allows a selection of various parameters or 

choices.  Simply scroll up or down until your selection is highlighted, then press the > 

key, the highlighted area will move across to the right. Press the up or down keys to 

scroll through your choices, all changes are instant. To return to the main menu just 

press either  <  or ‘select’. 

 

For example: 

to listen to a phantom powered microphone on the internal  

loudspeaker: 

 

Switch on the dBbox2, you are now on the top menu. Use the up/down keys to 

highlight ‘Input”. Press the > key to move the highlighter to the right of ‘Input’. Press 

the up/down keys to scroll through the possibilities: 

 

Analogue 

AES BNC 

AES XLR 
SPDIF BNC 

Off 

 

When ‘Analogue’ is highlighted press either the < key or press “Select”. The highlight 

will now move back to ‘Input’. Press select. You are now in the analogue input menu. 

Press the down key to highlight “Gain”. Press the  > key and the 0dB gain setting will 

be highlighted. Use the up/down keys to adjust the gain setting (+70dB to -10dB in 

1dB steps) . The setting will move just by 1dB then speed up if the button is held 

down. Now press either < or “Select”. 

Scroll down to “Phantom” and press the > key. Press either up or down to switch 

phantom on. If you have plugged a phantom mic in and put in enough gain the mic 

will be heard through the speaker and will be metering on the display. 

To switch off the mic amp press “select” or the < key and scroll up to exit, then press 

”select”. you will be returned to the top menu. Alternatively just press the Vol+ and 

Vol- keys together. 

The menu system really is easier to use than it is to describe.
