Peavey 3G specifications Frequency Response, Directivity, Power Handling There are many different

that will attenuate the signal more the larger the signal is, very similar to a compressor. This is accom- plished through the use of a spe- cially 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 tempo- rary 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. Peavey Electronics rates this unit's system power handling using a modified form of the AES Standard 2- 1984, utilizing audio band limited (20 Hz - 20 kHz) pink noise with peaks over 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. The test signal contains large amounts of very low-frequency energy, effectively simulating the frequency content of live music situations. The full measure of high frequencies in the test signal allow for exposure of the speaker system to synthesized tones that may extend beyond audibility. This rating is contingent on having a

minimum of 3 dB of amplifier headroom available so as to ensure that clipping does not occur.
