I know this forum zeroes in on video, but I assume some people here must know a lot about sound.

I'm looking for a...
  • portable PA system
  • loud enough to be used for conferences in rooms with up to 50-80 people
  • with either two wireless microphones or one wireless/one wired
  • with an audio output to digital recorders (either XLR or plain sound jacks).
What brands/models would you recommend?

Thank you.
