STAGE MONITOR AND P.A. LOUDSPEAKER PLACEMENT
For maximum rejection of unwanted sound, place the stage
monitor(s) or P.A. system loudspeakers at a 60 angle from the
rear of the Beta 56, not directly behind it (see Figure 1). Always
check out the stage setup before a performance to ensure opti-
mum placement of microphone and monitors.
