Frequency Response, Directivity, Power Handling

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 may 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™ 4G is measured at a distance of 1 meter using a 2.0 volt swept-sine input signal. As shown in Figure 1, the selected drivers in the SP™ 4G combine to give a smooth frequency response from 39 Hz to 17.5 kHz.

DIRECTIVITY

Beamwidth and directivity factors are derived from the -6 dB points from the polar plots (see Figure 3), which are measured in a whole space anechoic environment. 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 SP™ 4G exhibit 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 to 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.

The system supports both UHF and digital transmission, ensuring that users can select the best option for their specific needs and circumstances.

A notable technological innovation in the Peavey 4G is the inclusion of intelligent frequency management. This feature actively scans and detects the best available frequencies and automatically assigns them to the transmitter and receiver, optimizing signal clarity and minimizing dropouts. This is particularly beneficial in congested areas where multiple wireless devices are operating simultaneously.

No less impressive is the construction of the Peavey 4G hardware. Built with rugged, durable materials, the system is designed for the rigors of live performance. The transmitters and receivers are lightweight yet sturdy, allowing performers to move freely without the worry of equipment failure. Additionally, the ergonomic design ensures that both components fit comfortably in the user’s hands or pockets.

Ease of use is another vital characteristic of the Peavey 4G system. The user interface is intuitive, featuring clear LED indicators that provide real-time information about battery life, signal strength, and frequency selection. This simplicity allows even novice users to set up and operate the system with confidence.

Moreover, the Peavey 4G offers multiple output options, including balanced XLR and unbalanced ¼-inch outputs, making it compatible with a wide range of audio equipment, from mixers to amplifiers. Its versatility extends further with multi-channel capability, allowing users to operate multiple transmitters simultaneously without interference.

In summary, the Peavey 4G wireless audio system is engineered to meet the demands of modern audio professionals, combining advanced technology with user-centric design. Its impressive range, intelligent frequency management, durable construction, and ease of use make it an ideal solution for enhancing live sound experiences, ensuring that performers can focus on their art without being hindered by their equipment.
