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.
