About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

JH Audio Debuts Flagship In-Ear Monitor with Exceptional Treble by Knowles’ New Balanced Armature Supertweeter

The new Sharona IEM is first-of-its-kind with precise, well-rounded sound

Knowles Corporation (NYSE: KN), a market leader and global provider of advanced micro-acoustic microphones and speakers, audio solutions, and high-performance capacitors and RF products, is proud to partner with JH Audio as it debuts Sharona: a 16-driver IEM with four-way crossover designed to deliver best-in-class sound quality to top performers and sound engineers. JH Audio, a leading in-ear technology brand pioneered by sound engineer Jerry Harvey, introduces Sharona as the first IEM to incorporate the superior treble output capability of the new Knowles balanced armature Supertweeter.

The Knowles Supertweeter features a patented coil design with reduced inductance, paired with a specially constructed high-stiffness, low-mass reed, to deliver unprecedented output and treble frequency extension without requiring an amplifier or transformer. The Supertweeter’s small form factor is easier to integrate compared to alternative technologies such as MEMS or electrostatic drivers. The Supertweeter’s small size and ability to reach an ultra-high frequency of 40kHz also make it an ideal option for delivering lossless and high-resolution audio in premium True Wireless Stereo (TWS) earphones.

Sharona hits the pro audio market with a proprietary design comprised of 16 Knowles balanced armatures: four Supertweeters, four woofers, four midranges, and four tweeters. The Supertweeter takes treble performance to a whole new level, and in tandem with the other 12 drivers enables high-definition audio to give musicians a realistic, beautiful music experience. Equipped with JH Audio’s patented Freqphase™ Technology for phase accuracy, Sharona delivers unmatched output, realistic instrumental detail, and equalization capabilities for superior performance in a comfortable form factor.

“Exceptional sound quality is a key differentiator for musicians and sound engineers who rely on in-ear monitors on stage and in the studio,” shares Jon Kiachian, Vice President and GM of Knowles Hearing Health Technologies. “The new Supertweeter offers exceptionally clean extended treble via its unique coil and reed designs, and we’re proud to partner with JH Audio as they continue to create solutions favored by music professionals and audiophiles alike.”

“We've been trying to achieve this frequency response for years. It wasn't possible until JH Audio partnered with Knowles to develop the new Supertweeter,” says Jerry Harvey, President & Founder at JH Audio. “The addition of the Supertweeter delivers expansive stereo imagery full of depth and width while creating more air for high-range reproduction. Sharona is the best IEM I've ever designed, and we're excited for everyone to hear it.”
