System shuts down when driven hard.

1.) Insufficient amplifier power.  Amplifier goes into protect mode

due to overcurrent or thermal stress.  Switch to a larger

amplifier.

2.) Line impedance too low. (PI models in particular)  Some

amplifiers will not drive a 2 ohm load at full power, especially if

both channels are loaded to 2 ohms.  (A pair of Sx600PI

systems on the same line is a 2 ohm load.)  Use a different/

bigger amplifier, convert to PIX versions, or reconfigure lines

with more amp channels and fewer speakers per line.

3.) Incorrect high-pass filter or no filter at all.  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.

4.) 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

1.) 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.

2.) 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 intelligibility of speech.  Use only enough EQ to

tame the very worst room resonances (which should not be a

problem outdoors) keeping the notch width as narrow as

possible.  The best solution is to keep the announcer close to
