[. . . ] The effect that this has is to decrease the signal level going to the 44XTTM by about 6 dB so that it will not be damaged due to long term (thermal) overpowering. Short duration transients will not be attenuated by Sound Guard 44XTTM and have the possibility to damage the 44XTTM. 50 100 200 Figure 1 500 1k Frequency (Hz) 2k 5k 10k 20k Impedance 100 50 30 20 Z ( ) 10 5 3 2 1 20 50 100 200 500 1k Frequency (Hz) 2k 5k 10k 20k Figure 2 Beamwidth 360 300 Beamwidth (Degrees) 180 140 100 80 60 40 30 20 Horizontal Vertical 50 100 200 500 1k Frequency (Hz) 2k 5k 10k 20k Figure 3 Q & Directivity Index 100 20 Q 10 10 Di 1 20 50 100 200 Figure 4 500 1k Frequency (Hz) 2k 5k 10k 0 20k HORIZONTAL POLAR PATTERNS 1 octave averaged, plotted on ISO 1 octave centers from 250 Hz to 8 kHz 0 30 o o 0 -30 o o 0 -30 o o 30 o 30 o -30 o 60 o -60 o 60 o -60 o 60 o -60 o 90 o -90 o 90 o -90 o 90 o -90 o 250 Hz 500 Hz 1 kHz 0 30 o o 0 -30 o o 0 -30 o o 30 o 30 o -30 o 60 o -60 o 60 o -60 o 60 o -60 o 90 o -90 o 90 o -90 o 90 o -90 o 2 kHz 4 kHz 8 kHz VERTICAL POLAR PATTERNS 90 o 90 o 60 o 60 o 90 o 60 o o 30 o 30 30 o 0 o 0 o 0 o -30 o -30 o -30 o -60 -90 o o -60 -90 o o -60 -90 o o 250 Hz o 500 Hz 1 kHz o 90 90 90 60 o o 60 o 60 o 30 o 30 o 30 o 0 o 0 o 0 o -30 o -30 o -30 o -60 -90 o o -60 -90 o o -60 -90 o o 2 kHz 4 kHz 8 kHz When operating the SPTM 1G in bi-amp mode with an active crossover, the CS® X1 input/crossover module for the CS® 800S is recommended. This crossover is designed specifically for this type of loudspeaker. It may be obtained as an add-on feature to the CS 800S at a modest cost. The proper configuration for this crossover module when using it with the SPTM 1G is to have it set to SPTM 2 mode and reverse the polarity of the high-frequency driver. This will give the best possible sonic and directional performance from the SPTM 1G without spending hundreds of dollars for a fully programmable digital crossover. whole space anechoic environment. These are specifications that provide a reference to the coverage characteristics of the unit. These parameters provide insight for proper placement and installation in the chosen environment. The blending of the components of the SP 1G exhibit a desirable beamwidth and directivity (Figures 3 and 4) suitable for sound reinforcement applications. available so as to ensure that clipping does not occur. ARCHITECTURAL AND ENGINEERING SPECIFICATIONS The loudspeaker system shall have an operating bandwidth of 50 Hz to 19 kHz. The nominal output level shall be 99 dB when measured at a distance of one meter with an input of one watt. The maximum continuous power handling shall be 450 watts, maximum program power of 900 watts and a peak power input of at least 1, 800 watts, with a minimum amplifier headroom of 3 dB. The nominal radiation geometry shall be 77 degrees in the horizontal plane and 63 degrees in the vertical plane. [. . . ] Box 2898, Meridian, Mississippi 39302-2898.
