Hi.
You're welcome.
As You well know, the problem with Behringer topics is that either the feedback is sparse, or if there's enough participants (the same ones every time

) the discussion gets so heated off-topic that the thread end up closed. I think that's a shame, despite their problems, Behringer is here to stay. Forever.
Since I'm a separates guy, and only recommend any powered mixer in the duty I think they suit the best, ie. background music in fixed locations with random, disposable speakers, I'm not necessarily the guy to promote the use of one

.
That said, If Your PA speakers are decent and can handle the said Behringer, I'd think it'll perform well in an occasional gigging duty.
If You have to buy new speakers also, a pair of active speakers and a "normal" mixer would be the route I'd take.
Regards
Sam
