STAGE MONITOR & P.A. LOUDSPEAKER PLACEMENT
For maximum rejection of unwanted sound, place the stage moni-
tor(s) or P.A. system loudspeaker at a 60° angle from the rear of
the BETA 58A, not directly behind it. Always check out the stage
setup before a performance to ensure that microphone and moni-
tor placement is optimum.
