Topic: 2-3 vocals and piano all through small (1 speaker) PA: which mics would you use?

[bbernardini]

Small club, small crowd, small PA (2-3 vocals and an electronic piano through one speaker). I know neither one of these is the ideal, but if you had to choose, would you use SP-CMC-19s, or the internals of the Edirol R-09?

The external mics should sound better then the internals
