If I set my speakers may 4 or 5 feet to the rear of me off to either side maybe 15' to 20' apart will I be able to hear myself or will I need a monitor also? The band stand is about 3 feet off of the floor. This is my first solo gig in such a large facility with such a large platform.

If I decide to use my Rogue PA for a monitor and put it off to the side or behind me maybe a couple of 3 feet away, is this a castrophy waiting to happen with feed back?

Should I use the reverb and other settings from the Mackie and leave the settings on the Rogue flat? My Rogue is a 50 watt 10" speaker. My mains are Peavey TLS 15" with a Mackie 808S.

Any suggestions will be appreciated.
