MIC 1 ZONE 1 2 3 MONITOR 4 The front panel LEVEL and ZONE switches are the same for all channels. Simply activate the appropriate switches to send that channels information to the required output zone. OUTPUT 1 ZONE ONE The output XLR’s 1-4 are line level balanced outputs. Q: I am getting distortion out of all of the XLR outputs and the level is very high? A: You are plugging the line level outputs into something that is MIC level. You will always get distortion and excessive volume.

OPERATION AND SET UP CONT. MASTER VOLUME ZONE 1 ZONE 2 ZONE 3 ZONE 4 The MASTER VOLUME controls on the front of the RM424 function just as the name implies. NOTE: with channel volumes, master volumes and possibly remote volumes there are plenty of opportunities to get distortion on the outputs. It is best to set all volumes at half (white pointer facing up). Then make adjustments from there as needed.
