User manual PEAVEY SP 3G DATASHEET

[. . . ] The system is comprised of a 15" Black Widow woofer with Kevlar-impregnated cone, a 6. 5" professional mid-range driver, and a 22XT compression driver coupled with a CH 3 constant directivity horn. This unit can be driven in a fullrange or bi-amp mode by simply plugging into the desired jack on the input plate. [. . . ] This is accomplished through the use of a specially selected dynamically resistive light bulb. If the bulb in your Sound Guard should ever burn out, a replacement may be obtained from an Authorized Peavey Service Center. However, if a Peavey replacement bulb is not readily available, an automotive type 1156 bulb can be substituted for temporary use until a Peavey bulb can be obtained. FREQUENCY RESPONSE This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SP 3G is measured at a distance of 1 meter using a 2. 8 volt swept-sine input signal. As shown in Figure 1, the selected drivers in the SP 3G combine to give a smooth frequency response from 54 Hz to 17 kHz. 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 on-axis measurement position. These are specifications which 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 3G exhibits a desirable beamwidth and directivity (Figures 3 and 4) suitable for sound reinforcement applications. POWER HANDLING There are many different approaches to power handling ratings. [. . . ] ONE YEAR LIMITED WARRANTY NOTE: For details, refer to the warranty statement.
