Q: 9. Can I use it for vocal (singing) only?

A: Yes, the Boss ACS Pro can be used for vocals. The amp's XLR-1/4" combo jack input can be used to connect a vocal mic for singing.

Q: 10. How do I get more paging volume?

A: If you've maxed out the volume knob on the input and master output, there are few things you can look at. Consider what the speaker taps are set to, also speaker sensitivity has a direct impact on how loud the speaker will sound. Take a look at the source. Is it mic or line? All of these things affect the level. If you've addressed these concerns, and your system isn't loud enough, chances are you may need more power; either on the speaker side, or the amp side.
