JBL AUDIO ENGINEERING FOR SOUND REINFORCEMENT

by John Eargle and Chris Foreman

This book comprehensively covers all aspects of speech and music sound reinforcement. It is divided into four sections: Section 1 provides the tuto- rial fundamentals that all audio engineers will need, discussing subjects such as fundamentals of acoustics, psychoacoustics, basic electrical theory and digital processing. Section 2 deals with the fundamental classes of hardware that the modern engineer will use, such as loud- speaker sys tems and components, microphones, mixers, amplifiers and signal processors. Special at tention is given to digital techniques for sys tem control and to audio signal analys i s. Se ction 3 deals with the basics of sys tem design, from concept to final realization. It covers topics such as basic sys tem type and speech intelligibility, s i te survey, user needs analysis and project management. Section 4 discusses

individual design areas, such as sports facilities, large-scale tour sound syste m s, high- level music playback, systems for the theater, religious facilities, and other meeting spaces. The book is written in an accessible style, but does not lack for ample amounts of technical information. JBL and HPro brand products are prominently feature as examples to illustrate the principles and applications. Available at bookstores and on line.

Studio Monitors specifications

JBM electronic Studio Monitors have carved a niche for themselves in the competitive audio monitoring market, especially favored by musicians, producers, and sound engineers. These monitors are engineered to deliver accurate sound reproduction, ensuring that audio professionals can trust the source material they are working with.

One of the main features of JBM Studio Monitors is their impressive frequency response. They typically cover a wide range, often extending from 40 Hz to 20 kHz. This broad spectrum allows for a comprehensive listening experience, revealing nuances in recordings that might be missed with less accurate speakers. Additionally, many models incorporate advanced bass reflex designs, enhancing low-frequency performance without distortion.

The build quality of JBM monitors is another standout characteristic. Constructed from high-density MDF, they minimize resonance and provide a cleaner sound. The enclosure design works in tandem with the speaker's drivers to deliver clarity across different sound levels. The use of professionally tuned port systems ensures that low-end frequencies are reinforced, resulting in a punchy yet balanced bass response.

In terms of technology, JBM Studio Monitors often employ Class A/B amplifiers, which combine the strengths of both Class A and Class B to deliver power and efficiency. This amplification approach is integral to achieving minimal distortion, allowing for precise audio playback. Some models feature bi-amped designs, using separate amplifiers for the woofer and tweeter, further enhancing the monitors' fidelity and dynamic range.

Another notable feature in JBM electronic Studio Monitors is their room adjustment controls. Many units come equipped with equalization settings that allow users to tailor the sound profile to their specific environment, compensating for room acoustics and ensuring optimal playback. This adaptability is crucial in a professional setting where space can vary greatly.

Connectivity options are abundant, often including TRS, XLR, and RCA inputs, making these monitors versatile and compatible with various audio interfaces and mixers. The user-friendly design extends to ease of placement, with some models compact enough to fit in smaller studio setups while still delivering powerful sound.

In summary, JBM electronic Studio Monitors are designed to offer unrivaled sound accuracy and flexibility for audio professionals. With features like a wide frequency range, robust build quality, advanced amplification technology, and useful room tuning options, these monitors stand out as a worthy investment for anyone serious about sound production. Their reputation for reliability and performance makes them a popular choice among those in the audio industry.
