The HF section employs a 1. 6" exit/100 mm voice coil compression driver mounted on one of Peavey's revolutionary new Quadratic Throat Waveguides. [. . . ] The HF section employs a 1. 6" exit/100 mm voice coil compression driver mounted on one of Peavey's revolutionary new Quadratic Throat Waveguides. The ILS 1294 has a full range sensitivity of 96 dB SPL ­ (1 Watt/1 meter) and a maximum output of 130 dB at 1 meter (full range). Harmonic Distortion : 1% Rated Power The Peavey ILS 1294 is a high performance loudspeaker system for use in demanding sound reinforcement applications. The robust construction of the ILS 1294 provides power handling capacities of 750 W continuous, 1. 5 kW program and 3. 0 kW peak (full range). The unit may be operated using the internal passive crossover or may be biamplified. Twelve 3/8" x 16 threaded mounting suspension points (3 each top and bottom and 2 each sides and back) allow a variety of suspension configurations. Multiple units may be mounted to form a vertical/horizontal 110 100 dB SPL (re 20 Pa) 90 80 70 60 50 40 20 50 100 200 500 1k Frequency (Hz) 2k 5k 10k 20k Figure 6 3 2nd Harmonic 3rd Harmonic array [see limitations under mounting instructions]. Both versions of the ILS 1294 are solidly constructed of 3/4" void free poplar plywood and finished with an exterior grade hardened black paint. Harmonic Distortion Second and third harmonic distortions vs. frequency are plotted in figures 5 and 6 for two power levels, ten percent (10%) of rated input power and either one percent (1%) of rated input power or one Watt, whichever is greater. 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 LX 20 exhibit a desirable beamwidth and directivity (Figure 3 and 4) suitable for sound reinforcement applications. Power Handling There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a full-range form of the AES Standard 2-1984. Using audio band 20 Hz to 20 kHz pink noise with peaks of four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand today's high technology music. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available. Architectural and Engineering Specifications The loudspeaker system shall have an operating bandwidth of 63 Hz -- 18. 5 kHz. The nominal output level shall be 96. 0 dB when measured at a distance of one meter with an input of one Watt. The nominal impedance shall be 8. 0 Ohms. [. . . ] The nominal output level shall be 96. 0 dB when measured at a distance of one meter with an input of one Watt. The nominal impedance shall be 8. 0 Ohms. The maximum continuous power handling shall be 750 Watts, maximum program power of 1, 500 Watts and a peak power input of at least 3, 000 Watts, with a minimum amplifier headroom of 3 dB. [. . . ]
