[. . . ] 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. In the LTD HBH unit, the waveguide is rotated to provide a corresponding beamwidth which may be employed in low ceiling type applications. Both versions of the LTD HB have a full range sensitivity of 95 dB SPL ­ (1 watt/1 meter) and a maximum output of 130 dB at 1 meter (full range). The Peavey LTD HB is a high performance loudspeaker system for use in demanding sound reinforcement applications. The robust construction of the LTD HB provides power handling capacities of 750 w continuous, 1. 5 kW program and 3 kW peak (full range). The unit may be operated using the internal 1, 600 Hz passive crossover or Figure 5 2nd Harmonic 3rd Harmonic Harmonic Distortion : 1% Rated Power 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 may be biamplified. Twelve 3/8 inch x 16 threaded mounting suspension points (three each top and bottom and two each sides and back) allow a variety of suspension configurations. Multiple units may be mounted to form a vertical/horizontal array [see limitations under mounting instructions]. Box Meridian, Mississippi 39301-2898. Frequency Response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the LTD HB is measured at a distance of 1-meter using a 1 watt (into the nominal impedance) swept-sine input signal. As shown in Figure 1, the selected drivers in the LTD HB combine to give a smooth frequency response from 47 Hz - 18. 5 kHz. 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. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. Directivity Beamwidth is derived from the -6 dB points from the polar plots (see Figure 3) which are measured in a whole space anechoic environment. Q and Directivity Index are plotted for the onaxis measurement position. [. . . ] As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion.
