Q: Why can’t I change the Gain in the AmpTraXX application? 

A:  You are connected to AmpTraXX in Live Mode and the front panel volume controls are enabled.  Whenever 
these controls are enabled, the gain controls will only display the current value represented by the knobs on the 
front of your AmpTraXX.  To control volume remotely, you must disable the front panel controls by flipping 
DIP switch #1 to the 

OFF

 (

Up

) position. 

 

Q: The Blue LED is blinking, and AmpTraXX doesn’t seem to be working. Why? 

A:  AmpTraXX is either not configured for normal operation or it may have experienced a serious error.  
Compare the LED’s behavior to the table in the 

Front Panel

 section of this manual to determine the exact 

cause.  Most likely, DIP switch #3 is in the OFF (up) position and AmpTraXX is waiting for a firmware 
upgrade.  Returning this switch to the ON position should resume normal operation.
