Created cdg's work great on personal system and computer but not on pro system

[Steve Elam]

Imported music from audio cdg using microstudio. Opened wav file in vogon 2, removed vocals or as much as I could in vogon 2. Found to my surprise that I could remove all vocals from same wav file using vogon 1. Created cdg using vogon 1 and karaoke home pro. Everything came out great on my personal computer and small home karaoke system, lyrics, music, everything. But,when I played these same cdg's on a professional system everything that I created was there but the audio. The music could only be heard and not very loud at all, when the amps were turned up to the highest peak of almost to point of tremendous feedback. I have heard that there are settings on pro-systems that can be made to remedy my problem. Can anyone tell me what to do or what settings can be made on pro-systems?
