Stage Monitor and P.A. Loudspeaker Placement

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 56A, not directly behind it (see Figure 1). Always check out the stage setup before a performance to en- sure optimum placement of microphone and monitors.
