    CAUTIONS AND TROUBLESHOOTING Feedback Observe care in selecting P.A. volume, transmitter location and speaker placement so that the acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omni directional mics pick up sound equally from all direction, and are prone to feedback if not used carefully.

  • Page 12: Tips

    TIPS • The receiver antennas should be kept away from any metal surface. • If the Volume Control of the receiver is set too high, it may over-drive the input of the mixer, causing distortion. Conversely, if the output is set too low, the overall signal to noise ratio of the system may be reduced.
