If the speakers are too low, the people inthe back of the audience will not receive the best quality sound. If the speakers are too high, people in the front of the audience will not receivethe best quality sound. Pay attention to the coverage pattern of each speaker and aim them so that the entire audience is within the coveragepattern of the system. Utilize the downward angle pole cup on the SRX812P and SRX815P for closer audiences in smaller spaces.Place the speakers between the microphones and the audience.Feedback occurs when the microphones pick up sound from the speakers and “feed” the sound back through the sound system. If space islimited, point the speakers away from the microphones to reduce feedback.Locate the speakers away from turntables.Low-frequency feedback occurs when the output of the speaker is picked up by the tone arm of the turntable and is re-amplified. A heavy, solidturntable base and shock mounting can also reduce this type of feedback in DJ applications.Use more speakers in large or highly reverberant spaces.Spreading speakers throughout these spaces will produce much better sound than trying to compensate with loudness level or equalization. Forvery long distances, the use of another set of speakers with time delay is recommended.Stand speakers upright for PA - Lay speakers on their side for stage monitoring.Use the full range speakers in upright stance for even coverage over a wide area. SRX815P and SRX812P speakers are also designed with aslanted position for stage monitoring applications. Rest the speaker on the side with rubber feet for use as a stage monitor. Two SRX835Ps canbe splayed side by side for wide coverage for large audiences. Simply stand them so that their inside side panels meet. This configuration is idealatop an SRX828SP subwoofer.SuspendedPole MountTripod StandMonitorFloor Standing Subs with 3-way splayedStacked Subs Cardiod Subs Cardiod Subs VerticalOUTINCH2CH 1OUT NETWORKLINKMASTER LEVELBACKPOWERDATAINA HARMAN INTERNATIONAL COMPANY DESIGNED AND ENGINEERED IN THE USAMADE IN MEXICOSERIAL NO.
