1. FLEX SOUND SYSTEM One of the most consistent and frustrating problems encountered by traveling performers is the lack of physical space available within the performing environment Previous attempts to remedy this problem have simply offered scaled down versions of existing systems The results have been acceptable but with many trade offs The smaller systems usually suffer from lack of low frequency response and quite often are very inefficient requiring a large amount of peripheral equipment to make up for their lack of design efficiency The new Peavey Tri Flex system addresses this particular problem in a very unique and effective manner FIGURE 1 Low frequency dispersion characteristics below 250 Hz FIGURE 2 requencies below 250 Hz are essentially non drectional the low frequency sub woofer may be placed in simost any convenient location within he Saisie ronnan oie rectangles reprenant possibi low frequency enclosure locations FIGURE 3 SYSTEM SET UP s Speaker Enclosure Placement The low frequency enclosure may be placed in almost any conventional location within the performing area Since low frequencies below 250 Hz are essentially nondirectional its location is not critical see figure 2 For maximum low frequency coupling and optimum system performance the low frequency enclosure should be placed on the floor with the slot radiator oriented downward and toward the listening audience2. The satellite speakers should be mounted on the tripod stands included and elevated to the approximate ear level of the audience These high frequency enclosures should be placed at conventional stage side locations to the side and slightly in front of the forwardmost microphone location see figure 3 FIGURE 4 FULL RANGE OPERATION AMPLIFIER SPKR OUT SATELLITE SATELLITE SPEAKER SPEAKER HI INPUT HI INPUT LOW FREQUENCY ENCLOSURE HI OUTPUTS e Full Range Operation A passive crossover network is housed inside the low frequency enclosure providing the inputs for the Tri Fiex system For full range operation connect speaker cables as shown in figure 4 We recommend speaker cable with 18 gauge or larger wire size Bi Amp Operation Bi amping the Tri Flex will provide greater system reliability increased power handling and lower distortion levels with a resulting increase in system efficiency and performance see figure 5 NOTE THE RECOMMENDED CROSSOVER FREQUENCY FOR BI AMPING THE TRI FLEX IS 250 Hz IF A STANDARD CROSSOVER NETWORK IS UTILIZED FOR THE CROSSOVER FUNCTION AN 18 dB PER OCTAVE ROLL OFF RATE IS NECESSARY FOR OPTIMUM PERFORMANCE FROM THE TRI FLEX FIGURES BI AMP OPERATION ABOVE 250 Hz SATELLITE SATELLITE LOW FREQUENCY ENCLOSURE SPEAKER SPEAKER Hi OUTPUTS HI INPUT HI INPUT _ FIGURE 6 cs 400 FROM MIXER LOW FREQUENCY ENCLOSURE SA
