First of all, because the Behringer is a single speaker, and the 
DTXpress module has a dedicated mono output, you don't need to find a 
special way to convert stereo to mono. The mono cable isn't a 
problem. I don't have a clue what the output level from the module 
is, but if it's too low for the Behringer line input, a DI box would 
balance the line, probably help to keep hum and signal noise down, 
suitably lower its impedance to match that of the mic input, and  
maybe attenuate the resulting signal sufficiently to protect the 
preamp on the Behringer from overload and distortion. Why not try it? 
DI boxes aren't necessarily expensive; some are $30 to $40. Maybe 
someone else has an informed view.
