7. All Sx600 models MUST BE HI PASSED See step 5 above but PIX models may cause amplifier shut down due to transformer saturation at high levels caused by low frequency transients or heavy bottom octave program content Verify that the CORRECT hi pass filtering is in use at all times Amplifier is simply being overdriven and going into protect mode With an oscilloscope on the amplifier output adjust compressor limiter to keep amplifier s out of clipping If the system has no comp limiter add one to the signal chain and be sure it is properly set Inconsistent intelligibility in audience area 4 Improper aiming If intelligibility decreases near the speaker the down angle is set too high If the intelligibility is great right under the speaker but suffers as you begin to move away from it the down angle is set too low Intelligibility across the horizontal plane side to side can be affected by a sloping audience area reflections from nearby walls or other barriers and trees banners and other objects obstructing and or reflecting the sound in an adverse way EASE is an excellent tool for predicting the correct aiming but in actual use these angles may need to be adjusted Over equalization The primary speech fundamentals are found in the 300Hz to 3kHz range most consonants are affected by the 3kHz to 6 kHz band and sibilance is mostly from 6kHz on up Substantial EQ cuts in any of these regions will seriously degrade the intel
