[. . . ] 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. [. . . ] DIRECTIVITY: Beamwidth is derived from the -6 dB points from the polar plots (Figure 3) which are measured in a whole space anechoic environment. Q and Directivity Index are plotted for the on-axis measurement position. 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 Impulse 1012 (8 ohm) exhibit a desirable beamwidth and directivity (Figure 3 and 4) suitable for sound reinforcement applications.

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. 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 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. ARCHITECTURAL AND ENGINEERING SPECIFICATIONS: The 4 ohm loudspeaker system shall have an operating bandwidth of 72 Hz 18 kHz. [. . . ] All associated rigging is the responsibility of others.
