STAGE MONITOR & P.A. LOUDSPEAKER PLACEMENT

For maximum rejection of unwanted sound, place the stage

monitor or P.A. system loudspeaker at a 60° angle from the

rear of the Beta 57A, not directly behind it (see Figure 1). Al-

ways check out the stage setup before a performance to en-

sure that placement of microphone and monitors is optimum.
