I often tell little one liners before songs that get people laughing, but about once a month I get a section of the audience (it's almost always on my left side) who say they hear me when I sing, but they cannot hear my jokes.

I thought that there was nothing I could do about this outside of trying a different sound system or getting a different mic. I use two FBT Maxx 2A's on the floor tilted up towards the audience and the Crowne CM311A mic. Ok, I know that it would be better for the speakers to be on stands, but I am doing hundreds of relatively low paying gigs, and I want to save on setup time.

It occurred to me that maybe by turning on the compressor in the talk settings of my PSR-S950 could help. For those who are familiar with the S950 or familiar with compressors, what would be a good setting for public speaking that might solve this problem? Thanks!
