Phantom power measurement 
 

Phantom 

 

Connect your phantom mic cable to Ana Out L.  Phantom power will be measured on 

both live and neutral  (XLR pins 2 and 3) with a tolerance of +- 1 volt. 

 

 

Four Wire Box 
 

4 Wire Box 

 

This feature is analogue only. 

The dBbox2 will act as a four wire box using the internal microphone and speaker or 

headphones. Listen to incoming audio and adjust the volume using Vol- and Vol+. 

Up.  If the speaker is in use it will cut on talk to prevent feedback, the headphones 

will not. 

Press the down arrow to speak on the internal mic. The microphone passes through 

a limiter, the threshold of this limiter is set by
