[Harp-L] Amp>DI box>PA

[Greg Heumann <greg@xxxxxxxxxxx>]

The line-out on your amp is an unbalanced, high impedance signal. The  
purpose of the DI box is to change it to balanced, low impedance so  
that there is much less signal loss on the long run to the board.  And  
you are smart to use the amp itself for on-stage monitoring. Asking  
the sound guy to add you into the monitors at the front of the stage  
is a recipe for a feedback nightmare.
